Abstract
BACKGROUND Schistosomiasis affects approximately 230 million people worldwide. There is an increased incidence of schistosomiasis cases in France acquired from outside the country. This increases the risk of schistosomiasis outbreaks as observed in Corsica. Clinicians from non-endemic regions are not accustomed to diagnosing and managing this pathology. The objective of this study is to provide a better description of the clinical and paraclinical characteristics and disease evolution of affected children. METHODS Through the French Pediatric Nephrology Society and the Pediatric Infectious Pathology Group, we contacted all French pediatric centers that may have treated children with urinary schistosomiasis between 2013 and 2019. Age, sex, comorbidities, and clinical, biological, and radiological data (at discovery and follow-up) were collected retrospectively. RESULTS A total of 122 patients from 10 different centers were included. The median age was 14 years and the sex ratio M/F was 4:1. Hematuria was present in 82% of the patients while urinary tract abnormality was found in 36% of them. Fourteen patients (11%) displayed complicated forms of urinary schistosomiasis including 10 patients with chronic kidney disease. A total of 110 patients received treatment with praziquantel, which was well-tolerated and led to clinical resolution of symptoms in 98% of cases. CONCLUSION Patients with schistosomiasis present frequent kidney, urinary, or genital involvement. Systematic screening of patients returning from endemic areas is therefore recommended, especially since treatment with antiparasitic drugs is effective and well-tolerated. Enhancing medical knowledge of this pathology among all practitioners is essential to improve care and outcomes.

Abstract
BACKGROUND Diabetic nephropathy is one of the most common complications associated with diabetes. However, non-diabetic kidney disease has been reported in patients with type 2 diabetes at varying incidence rates. The objective of our study is to investigate the occurrence, clinicopathological characteristics, and inflammatory markers linked to diabetic and non-diabetic nephropathy (NDN) in patients with type 2 diabetes mellitus (DM). Additionally, we aimed to explore the possibility of identifying non-diabetic pathology using different biopsy indications. MATERIALS AND METHODS A total of 159 patients with type 2 DM who underwent renal biopsy at a tertiary care nephrology clinic between January 2000 and January 2022 were enrolled in the study. We collected comprehensive data, including patient demographics, co-morbidities, diabetes duration, renal biopsy indications and results, serological markers, renal function, diabetic retinopathy (DRP), full blood count, blood biochemistry, urinalysis, and inflammatory markers. Patients were categorized based on their biopsy indications, and their biopsy results were classified into three groups: isolated NDN, isolated diabetic nephropathy (DN), and mixed nephropathy with concurrent NDN. We evaluated the relationship between biopsy indications and accompanying pathologies and statistically assessed the likelihood of each biopsy indication detecting non-diabetic renal pathology. Additionally, differences in other data, including demographic and laboratory results and medical histories, among the three groups were investigated. RESULTS The most frequent indication of renal biopsy was atypical presentations of nephrotic syndrome or nephrotic range proteinuria (ANS/ANP) in 25.1% of patients. Other indications included unexplained renal failure (URF) in 22.6%, atypical presentations of non-nephrotic range proteinuria (ANNP) in 18.2%, acute kidney injury or rapidly progressive kidney dysfunction (AKI/RPKD) in 16.9%, microscopic hematuria in 15.7%, URF with ANNP in 11.3%, and severe nephrotic range proteinuria (SNP) in 9.4%. Renal biopsy revealed isolated NDN in 64.8%, DN in 25.1%, and mixed nephropathy in 10.1% of patients. Primary glomerular diseases were the main non-diabetic renal pathology, predominantly focal segmental glomerulosclerosis (FSGS) (36.4%) followed by MN (10.6%) and IgA nephropathy (7.5%). In comparison with the isolated DN and mixed nephropathy groups, patients in the isolated NDN group had significantly shorter diabetes duration, fewer DRP, as well as lower serum creatinine and neutrophil-to-lymphocyte ratio (NLR). Multivariate logistic regression analysis revealed that presence of hematuria (OR 4.40; 95% CI 1.34 - 14.46, p = 0.014), acute nephrotic range proteinuria (OR 11.93; 95% CI 1.56 - 90.77, p = 0.017), and AKI/APKD (OR 41.08; 95% CI 3.40 - 495.39, p = 0.003) were strong predictors of NDN. Lower NLR (OR 0.77; 95% CI 0.60 - 0.98, p = 0.035), shorter duration of diabetes (OR 0.90; 95% CI 0.84 - 0.97, p = 0.010), and absence of DRP (OR 0.35; 95% CI 0.12 - 0.98, p = 0.046) were also found to be independent indicators of NDN. Receiver operating characteristic curve (ROC) analysis revealed a cut-off value of ≤ 3.01 for NLR (sensitivity of 63.1%, specificity of 63.5%) with regards to predicting non-diabetic renal pathology (p = 0.006). CONCLUSION Renal biopsy findings in patients with type 2 DM highlight that the prevalence of NDN may be higher than assumed, as presented mainly in the form of primary glomerular disease. The presence of AKI/RPKD, hematuria, and ANS/ANP serves as a reliable indicator of non-diabetic renal pathology. In more ambiguous situations, factors such as a shorter duration of diabetes, absence of DRP, and a lower NLR value may assist clinicians in biopsy decision.

Abstract
OBJECTIVE To emphasize preventive measures and outline management strategies for inadvertent ureteral cannulation. METHODS We present a case report and conduct a literature review of 39 case reports on ureteral cannulation, examining a total of 48 patients. RESULTS About 67% of the cases were female, and long-term catheterization was observed in 67% of the cases. Neurological conditions such as spinal cord injury (SCI), stroke, dementia, multiple sclerosis, and myasthenia gravis were the primary factors (48%) in ureteral cannulation. Symptoms included flank pain (46%), fever (31%), oliguria (27%), non-deflatable balloon issues (25%), hematuria (21%), abdominal pain (17%), urine leak (12.5%), and nausea/vomiting (8%). Complications varied, including acute pyelonephritis (35%), acute kidney injury (27%), urosepsis (21%), and ureter rupture (17%). Despite inadvertent catheter placement, 25% of patients had no complications. More than half of the patients (58%) were managed through catheter change, while 27% underwent cysto-ureteroscopy with or without balloon puncture or ureteral stenting. Additionally, 10% received interventional radiology procedures, 6.25% underwent surgical repair, and 4% underwent ultrasound-guided balloon puncture. CONCLUSIONS Female gender, neurologic conditions, and long-term catheterization were identified as predominant risk factors. Early detection of ureteral cannulation can prevent severe complications, particularly in certain special populations such as patients with neurogenic bladder or SCI, who may have reduced sensation and expression capabilities.

Abstract
PURPOSE To investigate the influence of the initial clinical presentation (symptomatic vs. asymptomatic) on histopathological tumor features in patients with upper tract urothelial carcinoma (UTUC). METHODS We conducted a single-center, cross-sectional, and retrospective study that enrolled 72 adults with primary UTUC who underwent radical nephroureterectomy at our institution over a period of 4 years (April 2019-April 2023). RESULTS Symptomatic patients exhibited significantly higher frequencies of high-grade UTUC (73.6% vs. 36.8%, p = 0.006), ≥ T2 stage UTUC (60.4% vs. 26.3%, p = 0.007), and larger tumor sizes (median 5 vs. 4 cm, p = 0.015) compared to asymptomatic patients. Multiple regression analyses demonstrated significant associations between symptomatic presentation and the presence of high-grade UTUC (OR 6.35, 95% CI 1.81-22.27, p = 0.004), ≥ T2 stage UTUC (OR 5.98, 95% CI 1.62-22.08, p = 0.007), and larger tumor size (B 3.14, 95% CI 0.62-5.66, p = 0.015). A subset of patients with hematuria was separately analyzed to assess the influence of hematuria severity (gross vs. microscopic) on UTUC characteristics. Patients with gross hematuria exhibited significantly higher frequencies of high-grade UTUC (72.9% vs. 33.3%, p = 0.048) and ≥ T2 stage UTUC (58.3% vs. 22.2%, p = 0.001). Multiple regression analyses showed significant associations between gross hematuria and the presence of high-grade UTUC (OR 6.34, 95% CI 1.15-34.95, p = 0.034) and ≥ T2 stage UTUC (OR 6.54, 95% CI 1.11-38.93, p = 0.039). CONCLUSION Initial symptomatic presentation was independently associated with adverse histopathological UTUC characteristics, potentially attributed to earlier detection of UTUC in asymptomatic patients, before the onset of symptoms.

Abstract
OBJECTIVES To quantitatively describe the nature, severity, and duration of symptoms and functional impairment during recovery from transurethral resection of bladder tumors. MATERIALS AND METHODS All patients scheduled for transurethral resection were approached for enrollment in a text-message based ecological momentary symptom assessment platform. Nine patients reported outcomes were measured 7 days before surgery and on postoperative days 1, 2, 3, 5, 7, 10, and 14 using a 5-point Likert scale. Self-reported degree of hematuria was collected using a visual scale. Clinical data was collected via retrospective chart review. RESULTS A total of 159 patients were analyzed. Postoperative symptoms were overall mild, with the largest differences from baseline to postoperative day 1 seen in dysuria (median 0/5 vs. 3/5) and ability to work (median 5/5 vs. 4/5). Recovery was generally rapid, with 76% of patients reporting ≥4/5 agreement with the statement "I feel recovered from surgery" by postoperative day 2, although 15% of patients reported persistently lower levels of agreement on postoperative day 10 or 14. Patients undergoing larger resections (≥2cm) did take longer to return to baseline in multiple symptom domains, but the difference of medians vs. those undergoing smaller resections was less than 1 day across all domains. Multivariable analysis suggested that receiving perioperative intravesical chemotherapy was associated with longer time to recovery. 84% of patients reported clear yellow urine by postoperative day 3. CONCLUSION In this population, hematuria and negative effects on quality of life resulting from transurethral resection of bladder tumors were generally mild and short-lived, although a small number of patients experienced longer recoveries.

Abstract
SIGNIFICANCE STATEMENT Early identification of patients at risk of renal flares in ANCA vasculitis is crucial. However, current clinical parameters have limitations in predicting renal relapse accurately. This study investigated the use of urinary CD4 + T lymphocytes as a predictive biomarker for renal flares in ANCA vasculitis. This study, including urine samples from 102 patients, found that the presence of urinary CD4 + T cells was a robust predictor of renal relapse within a 6-month time frame, with a sensitivity of 60% and a specificity of 97.8%. The diagnostic accuracy of urinary CD4 + T cells exceeded that of ANCA titers, proteinuria, and hematuria. Monitoring urinary CD4 + T lymphocytes could help assess the risk of future renal relapse, enabling early preventive measures and tailored treatment strategies. BACKGROUND In ANCA-associated vasculitis, there is a lack of biomarkers for predicting renal relapse. Urinary T cells have been shown to differentiate active GN from remission in ANCA-associated vasculitis, but their predictive value for renal flares remains unknown. METHODS The PRE-FLARED study was a prospective multicenter biomarker study including 102 individuals with ANCA-associated vasculitis in remission aimed to predict renal relapse by quantifying urinary CD4 + T-cell subsets using flow cytometry at baseline and monitoring clinical outcomes over a 6-month follow-up. RESULTS Among the participants, ten experienced renal relapses, two had non-renal flares, and 90 remained in stable remission. The median baseline urinary CD4 + T-cell count was significantly higher in patients who relapsed compared with those in remission. Receiver operating characteristic curve analysis of urinary CD4 + T-cell counts showed an area under the curve value of 0.88 for predicting renal flares, outperforming ANCA titers, hematuria, and proteinuria. Using a cutoff of 490 CD4 + T cells per 100 ml urine, the sensitivity and specificity in identifying patients with future renal flares were 60% and 97.8%, respectively. In a post hoc analysis, combining urinary CD4 + T-cell counts with proteinase-3 ANCA levels suggested improved predictive performance in the PR3 + subgroup. In addition, the number of urinary CD4 + T cells showed a limited correlation with a decline in GFR and an increase in proteinuria over the follow-up period. CONCLUSIONS This study concluded that urinary CD4 + T-cell counts could identify patients with ANCA-associated vasculitis at a substantial risk of renal relapse within 6 months. Combining these counts with ANCA levels further improved the prediction of relapse.

Abstract
BACKGROUND Choriocarcinoma is a rare and highly malignant form of gestational trophoblastic disease that may develop following pregnancy, abortion, or a hydatiform mole. Renal metastatic involvement by post molar choriocarcinoma is even rarer. In this case report, we describe a unique case of post molar choriocarcinoma with a solitary renal metastasis in the absence of a primary uterine tumor and metastases in other sites, which presented with urological symptoms and spontaneous renal hemorrhage. CASE PRESENTATION A 41-year-old Persian woman with history of complete hydatiform mole presented with severe flank pain, nausea, vomiting, gross hematuria, and vaginal bleeding. Laboratory tests demonstrated a serum beta human chorionic gonadotropin hormone level of 60,000 mIU/mL. Imaging studies showed a lesion at the lower pole of the left kidney with active bleeding surrounded by hematoma, as well as an empty uterine cavity. Additionally, bilateral pleural effusion was detected without any lesion within the lungs. Subsequently, the patient underwent laparotomy, partial nephrectomy, and left para-ovarian cystectomy. Endometrial curettage was also carried out. The histopathology report revealed choriocarcinoma renal metastasis with high expression of beta human chorionic gonadotropin, cytokeratin 7, and Ki 67. Moreover, there were no malignant cells in the endometrial curettage specimens, and a corpus luteum cyst was found within the para-ovarian cyst. Further investigations revealed that the pleural effusion was free of malignant cells, and there was no evidence of metastatic lesions in the brain. As a result, the patient was referred to the oncology department to receive chemotherapy, and the beta human chorionic gonadotropin levels dropped to 5 mIU/mL after receiving courses of a standard regimen of etoposide, methotrexate, actinomycin D, cyclophosphamide, and vincristine/oncovin over 3 weeks. Finally, monthly measurements of beta human chorionic gonadotropin levels for 6 months indicated that levels have constantly remained within normal ranges, showing no evidence of recurrence or new metastasis. CONCLUSIONS Urological symptoms such as hematuria or spontaneous renal hemorrhage might be the only presentation of post molar choriocarcinoma with renal involvement. Thus, it can be beneficial to measure serum beta human chorionic gonadotropin levels among females of childbearing age who present with unexplained urological symptoms, especially if there is a history of prior hydatiform mole.

Abstract
BACKGROUND Bladder leiomyomas are rare benign growths in the bladder, comprising less than 0.5% of bladder tumors with only 250 cases reported globally. They are more common in women. This case involves a 70-year-old woman with recurrent leiomyoma, presenting with lower urinary tract symptoms and painless hematuria. A recurrent bladder leiomyoma is rarely reported, making its presence exceptionally rare. CASE PRESENTATION A 70-year-old Pakistani woman with hypertension and diabetes presented with lower urinary tract symptoms (LUTS) and painless hematuria. She had a history of similar symptoms in 2010, leading to a diagnosis of bladder leiomyoma via cystoscopy and biopsy. Imaging studies revealed a substantial 3.7 × 4 × 4.0 cm isodense mass with calcifications at the bladder base, along with bladder wall thickening and diverticula. Pathological examination during Transurethral Resection of Bladder Tumor (TURBT) confirmed the presence of bladder tissue with smooth muscle, ruling out malignancy. Immunohistochemical studies supported the diagnosis. A successful TURBT was performed, and the patient recovered well. DISCUSSION Recurrent bladder leiomyoma is a rarely-discussed topic in medical literature. This article primarily aims to review existing studies and present a detailed case study, shedding light on this rare phenomenon.

Abstract
BACKGROUND The forgotten ureteral stents (FUS) is one of the late complications of stent placement. This systematic review summarized different aspects of FUS and focused on the problems and solutions related to FUS. METHODS This systematic review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) statement. PubMed® and Embase® were searched from inception until October 1st, 2022. Eligible studies were those defining FUS as a stent unintentionally left in situ longer than at least 2 months. RESULTS Total 147 studies with 1292 patients were finally included. The mean indwelling time of FUS was 33.5 months (range from 3 months to 32 years). The most common initial cause for stent placement was adjunct treatment to urolithiasis (79.2%). The major forgetting reasons were patient-related (83.9%), which included poor compliance, lapse in memory, and misconceptions about the necessity of timely removal. Primary presenting complaints were flank pain (37.3%), lower urinary tract symptoms (33.3%), and hematuria (22.8%). Encrustation (80.8%) and urinary tract infections (40.2%) were the most common complications detected in patients with FUS. Computed tomography evolving as a preferred imaging test (76.1%) was indispensable for evaluating encrustation, migration, fracture and other complicated situations in patients with FUS. Besides, evaluation of kidney function and infection status was also of great importance. Multiple and multimodal procedures (59.0%) were often necessitated to achieve the stent-free status, and were mostly endoscopic procedures. Cystoscope was most commonly used (64.8%). Retrograde ureteroscopy (43.4%) and antegrade stent removal (31.6%) were often used when dealing with more complicated situations. Extracorporeal shockwave lithotripsy (30.4%) was often used as adjunctive to other endoscopic procedures, but it sometimes failed. The decision regarding the choice of treatment is based on the volume and site of encrustation, the direction of migration, the site of fracture, kidney function and other urinary comorbidities. CONCLUSIONS FUS not only pose hazard to patients' health, but also impose a huge economic burden on medical care. Thorough preoperative evaluation is fundamental to developing the treatment strategy. The management of FUS should be individualized using different treatment modalities with their advantages to minimize patients' morbidities. Prevention is better than cure. Strengthening health education and setting a tracking program are of great importance to the prevention of FUS.

Abstract
BACKGROUND In urology, ureteral stents are used to treat obstructive diseases. Hematuria (54%), fever, discomfort, and lower urinary system symptoms are the predominant symptoms related to ureteral stent. AIM This article links stent symptoms to double-j width and length, as well as patient's height, weight, and body mass index (BMI). Ureteric Stent Symptoms Questionnaire (USSQ) was used to measure ureteral stent symptoms at 1st and 4th week of stent in situ as well as the 4th week after pigtail removal. METHODS A 200-patient prospective study, where patients were allocated into four groups following ureteral stent insertion depending on the stent characteristics. Those groups were: 4.8 Fr./26 cm (Group A), 4.8 Fr./28 cm (Group B), 6 Fr/26 cm (Group C), and 6 Fr/28 cm (Group D). RESULTS Men comprised 53.5% of 200 patients. Participants had an average age of 49 ± 15.5 years, height of 175 ± 8.94 cm, and BMI of 23.8 ± 7.6 cm. The laboratory results were identical between groups. At the first and fourth week, groups had similar urine symptoms, pain severity, health status and occupational activities. The difference in pain location was statistically significant. Group A had 82.4% renal back pain in the first week, whereas Group B had 68.8%, Group C 31.3% and Group D 62.5 (p=0.04). At the fourth week, 64.7% of Group A patients reported kidney front pain, compared to 100% of Group B, 93.3% of Group C, and 100% of Group D (p=0.04). There was statistical significance in the sexual activity of the patients. 24.4% of Group C patients stopped sexual activity before stent installation, compared to 10.6%, 8.3%, and 6.4% of the other groups (p=0.03). A moderate percentage of patients had active sexual activity at week 4 (Group A: 7.8%, Group B: 5.8%, Group C: 8.2%, Group D: 4.1%), p=0.83. In multivariate analysis, urinary catheter group, age, weight, height, and BMI did not significantly affect urine index score (UIS), pain index score (PIS), general health (GH), quality of work (QW), and quality of sex (QS). CONCLUSIONS Despite various attempts to establish the best ureteral stent, the effect of double-j stent physical features on stent-related symptoms remained unknown. No verdict is conceivable without adequate empirical data.

Abstract
The differences in bladder cancer outcomes between the sexes has again been highlighted. Uncommon among cancers, bladder cancer outcomes are notably worse for women than for men. Furthermore, bladder cancer is three to four times more common among men than among women. Factors that might explain these sex differences include understanding the importance of haematuria as a symptom of bladder cancer by both clinicians and patients, the resultant delays in diagnosis and referral of women with haematuria, and health-care access. Notably, these factors seem to have geographical variation and are not consistent across all health-care systems. Likewise, data relating to sex-specific treatment responses for patients with non-muscle-invasive or muscle-invasive bladder cancer are inconsistent. The influence of differences in the microbiome, bladder wall thickness and urine dwell times remain to be elucidated. The interplay of hormone signalling, gene expression, immunology and the tumour microenvironment remains complex but probably underpins the sexual dimorphism in disease incidence and stage and histology at presentation. The contribution of these biological phenomena to sex-specific outcome differences is probable, albeit potentially treatment-specific, and further understanding is required. Notwithstanding these aspects, we identify opportunities to harness biological differences to improve treatment outcomes, as well as areas of fundamental and translational research to pursue. At the level of policy and health-care delivery, improvements can be made across the domains of patient awareness, clinician education, referral pathways and guideline-based care. Together, we aim to highlight opportunities to close the sex gap in bladder cancer outcomes.

Abstract
BACKGROUND Renal Resistive Index (RRI) is an important and non-invasive parameter of renal damage and it is associated with abnormal microcirculation or to a parenchymal injury. The aim of our study was to compare the RRI in a cohort of patients with renal diseases categorized in three groups: nephrotic syndrome (NS), acute nephritic syndrome (ANS) and patients with urinary abnormalities (UA). METHODS Four hundred eighty-two patients with median age of 48 years (IQR 34-62) with indications for kidney disease were included in the study. Biochemical analyses, clinical assessment with detection of NS, ANS and UA and comorbidities were reported. Renal Doppler ultrasound with RRI was evaluated in all patients at the time of enrolment. RESULTS NS was present in 81 (16.8 %) patients while ANS in 81 (16.8 %) and UA in 228 (47.3 %) patients. Patients with ANS showed significant higher RRI compared to both patients with NS [0.71 (IQR 0.67-0.78) vs 0.68 (0.63-0.73), p < 0.001] and UA [0.71 (0.67-0.78) vs 0.65 (0.61-0.71), p < 0.001]; RRI was higher in NS patients than in patients with UA [0.68 (0.63-0.73) vs 0.65 (0.61-0.71), p < 0.001]. Patients with ANS had significantly lower median estimated glomerular filtration rate (eGFR) compared respectively to NS and UA patients [19.7 ml/min vs 54.8 ml/min and vs 72.3 ml/min, p < 0.001], while renal length was significantly higher in patients with NS compared to both patients with ANS and UA [111.88 mm vs 101.98 mm and vs 106.15, p < 0.001]. Patients with ANS had more frequently hematuria and RRI ≥ 0.70 (p < 0.001) compared to both patients with NS and patients with UA. The multiple regression analysis, weighted for age, showed that RRI inversely correlates with eGFR (β coefficient = -0.430, p < 0.001). CONCLUSIONS Higher and pathological RRI were found in ANS than NS and UA. Renal resistive index in ANS reflects changes in intrarenal perfusion and microvascular dysfunction related to disease characteristics.

Abstract
Objective: The aim of this study is to assess the efficacy and safety of laparoscopic surgery in the treatment of pediatric ureteral fibroepithelial polyp (FEP) patients. Our hypothesis is that laparoscopic surgery can effectively treat FEPs while minimizing patient discomfort and complications. Our research aims to evaluate the clinical outcomes of the surgery, including postoperative symptom relief, improvement in kidney function, and risk of postoperative complications. Methods: The clinical records of 34 patients who underwent ureteral polyp surgery at the Department of Urology at Anhui Provincial Children's Hospital between May 2014 and February 2023 were retrospectively analyzed. All patients underwent laparoscopic surgery. Among the 34 pediatric patients, there were 31 males and 3 females, with 2 on the right side and 32 on the left side. Of these cases, 24 polyps were located at the ureteropelvic junction, while seven were found in the upper segment of the ureter and three in its middle segment. Patients' ages ranged from 4 years and 3 months to 15 years, with a median age of 8 years and 6 months. All children presented with varying degrees of hydronephrosis, and preoperative clinical symptoms included ipsilateral flank or abdominal pain, hematuria, and other discomfort. Preoperative examinations mainly comprised ultrasound, intravenous pyelography, CT, or magnetic resonance urography imaging studies, as well as diuretic renography. All pediatric patients underwent laparoscopic excision of the polyp segment of the ureter, followed by renal pelvis ureteroplasty or ureter-to-ureter anastomosis. Results: All patients underwent surgery without conversion to open surgery. The surgical duration ranged from 72 to 313 minutes, with an average of 179.5 minutes. The average intraoperative blood loss was 14 mL. Postoperatively, one patient experienced leakage at the anastomotic site; however, no other significant complications occurred during or after the procedure. Postoperative histopathology confirmed the presence of FEPs in the ureter for all cases. All patients experienced a favorable postoperative recovery, with hospitalization periods ranging from 3 to 16 days and an average stay of 8.6 days. A Double-J stent was inserted in all patients for a duration of 1 to 2 months after surgery, and upon removal, follow-up color Doppler ultrasound revealed reduced hydronephrosis within 1 to 3 months. Follow-up examinations were conducted at intervals ranging from 3 to 108 months postsurgery, with an average follow-up time of 42.2 months, during which no recurrence of ureteral polyps or symptoms such as pain and hematuria was observed. Conclusions: The findings of this study demonstrate that laparoscopic excision of the polyp segment of the ureter, renal pelvis ureteroplasty, and ureter-to-ureter anastomosis represent safe and effective treatment modalities for pediatric FEPs in the ureters. This technique offers several advantages, including minimal invasiveness, rapid recovery, and definitive therapeutic efficacy, which effectively alleviate clinical symptoms and improve hydronephrosis.

Abstract
ASPirin in Reducing Events in the Elderly (ASPREE), a placebo-controlled prevention trial of low dose aspirin, provided the opportunity to establish a biospecimen biobank from initially healthy persons aged 70+ years for future research. The ASPREE Healthy Ageing Biobank (ASPREE Biobank) collected, processed and stored blood and urine samples at -80degC or under nitrogen vapour at two timepoints, three years apart, from a willing subset of Australian ASPREE participants. Written informed consent included separate opt-in questions for biomarker and genetic testing. Fractionated blood and urine were aliquoted into multiple low-volume, barcoded cryotubes for frozen storage within 4 hours of collection. Specially designed and outfitted mobile laboratories provided opportunities for participation by people in regional and rural areas. Detailed, high quality demographic, physiological and clinical data were collected annually through the ASPREE trial. 12,219 participants contributed blood/urine at the first timepoint, 10,617 of these older adults provided 3-year follow-up samples, and an additional 1,712 provided saliva for DNA. The mean participant age was 74 years, 54% were female and 46% lived outside major cities. Despite geographical and logistical challenges, nearly 100% of blood/urine specimens were processed and frozen within 4 hours of collection into >1.4 million aliquots. After a median of 4.7 years, major clinical events among ASPREE Biobank participants included 332 with dementia, 613 with cardiovascular disease events, 1259 with cancer, 357 with major bleeds and 615 had died. The ASPREE Biobank houses and curates a large number of biospecimens collected prior to the clinical manifestations of major disease, and 3-year follow-up samples, all linked to high quality, extensive phenotypic information. This provides the opportunity to identify or validate diagnostic, prognostic and predictive biomarkers, and potentially study biological effectors, of ageing-related diseases or maintenance of older-age good health.

Abstract
INTRODUCTION Delayed intraperitoneal bladder rupture is a rare clinical occurrence, frequently overlooked and misdiagnosed due to its nonspecific clinical manifestations. However, literature provides only a limited number of cases reporting delayed intraperitoneal bladder rupture resulting from blunt abdominal injury. PATIENT CONCERNS A 72-year-old female pedestrian was struck by a vehicle and experienced sudden, severe abdominal pain on the 8th day following the injury. Abdominal B-ultrasound revealed a significant accumulation of peritoneal effusion. The abdominal puncture retrieved serosanguinous ascites. Then the patient was promptly transferred to our hospital. Upon transfer, the physical examination revealed the patient vital signs to be stable, accompanied by mild abdominal distension, slight tenderness, tension, and an absence of rebound tenderness. Urinalysis detected microscopic hematuria, while contrast-enhanced computed tomography (CT) revealed considerable fluid accumulation in the abdominal cavity, without evidence of solid organ damage, and the bladder was adequately filled. DIAGNOSIS The diagnosis of delayed intraperitoneal bladder rupture primarily relied on intraoperative observations. INTERVENTIONS An emergency exploratory laparotomy was performed, revealing a linear rupture at the dome of the bladder. Subsequently, the bladder rupture was repaired. OUTCOMES Postoperative cystography demonstrated full recovery and the patient was discharged 28 days post-surgery. The postoperative recovery was uneventful without any complications. CONCLUSIONS A well-distended bladder observed in CT does not definitively rule out the potential for bladder injury. False negatives may occur due to incomplete bladder filling during CT cystography. Retrograde cystography can identify cases missed by CT cystography. In cases of substantial intra-abdominal free fluid, surgical intervention should be actively considered for patients with blunt abdominal trauma without concurrent solid organ damage.

Abstract
AIMS To confirm the improved performance of the micro-hole zone catheter (MHZC) compared to a conventional eyelet catheter (CEC) in male users of clean intermittent catheterizations (CICs). METHODS Male self-catheterizing subjects, who used hydrophilic sleeved soft/flexible CIC as the only bladder emptying method, were enrolled into a multi-center, randomized, cross-over study performed across six European sites. Subjects tested the MHZC, featuring a drainage zone with 120 micro-holes and a CEC with two eyelets. The study consisted of four study visits (V0-V3), during which endpoints related to catheter performance (urinary flow-stops, bladder emptying, and intra-catheter pressure) were measured and two 4-week test periods at home (T1 and T2) where dipstick hematuria and user perception between catheters were evaluated. RESULTS Seventy-three male subjects with non-neurogenic and neurogenic bladder dysfunction (3:2) were enrolled. On average, catheterizations with the MHZC led to close to mean zero flow-stops compared to ≥1 flow-stops with the CEC, during both HCP- and self-led catheterizations (both p < 0.001). Residual urine at first flow-stop was significantly reduced for the MHZC compared to CEC (p = 0.001 and p = 0.004, for HCP- and self-led catheterizations, respectively). This was substantiated by a significantly smaller pressure peak at first flow-stop, a proxy for minimized mucosal suction (both HCP- and self-led catheterizations, p < 0.001). After home-use catheterizations, dipstick hematuria was comparable between catheters, whereas catheterizations were associated with significantly improved perception in favor of MHZC regarding bladder emptying, less blocking sensation, and improved hygienic catheterization compared to the CEC. CONCLUSION This study confirmed the evidence of improved bladder emptying with the MHZC compared to a CEC without the need to reposition the catheter. The MHZC therefore offers an enhanced benefit for the dependent CIC user securing complete bladder emptying in an uninterrupted free flow and reducing the need to reposition the catheter during emptying.

Abstract
The current research is designed to investigate the effect of propolis supplementation on the clinical manifestations in women suffering from uncomplicated cystitis. In this randomized double-blind, placebo-controlled trial, 120 women with uncomplicated cystitis were selected and randomly assigned into two groups to receive two 500 mg capsules of propolis or placebo daily for 7 days along with ciprofloxacin (250 mg). Clinical symptoms including hematuria, urinary frequency, dysuria, suprapubic pain, and urgency, as well as bacteriuria, were assessed before and after the intervention. After supplementation, participants in the intervention group had significantly fewer days of urinary frequency (p < 0.001), dysuria (p = 0.005), and urgency (p = 0.03). However, there was no significant difference between the two groups regarding hematuria and suprapubic pain (p > 0.05). Furthermore, the severity of bacteriuria decreased significantly in both groups. In conclusion, it seems that propolis supplementation in women with uncomplicated cystitis could improve urinary frequency, dysuria, and urgency. However, further clinical trials should be conducted to fully understand the effects of propolis in women suffering from uncomplicated cystitis.

Abstract
INTRODUCTION There are scant data on renal cell carcinoma (RCC) from relatively younger patients in South America using contemporary classification. METHODS Fifty-nine consecutively treated patients with RCC (≤40 years old) were assessed from the National Institute of Neoplastic Diseases in Peru from 2008 to 2020 (34 males; 25 females), age range of 13 to 40 years. RESULTS Most common presenting symptoms were flank pain (n = 40), hematuria (n = 19), and weight loss (n = 12). Associated conditions included 4 patients with proven or presumed tuberous sclerosis and 1 patient with von Hippel Lindau syndrome, all with clear cell RCC. Tumor histopathology was clear cell RCC in 32 of 59 (54%), chromophobe RCC in 6 of 59 (10%), and 5 of 59 (8%) each of papillary RCC and MiT family translocation-associated RCC. Four of 59 (7%) were FH-deficient RCC and 2 of 59 (3%) remained unclassified. The remaining tumors were isolated examples of clear cell papillary renal cell tumor, eosinophilic solid and cystic RCC (ESC RCC), RCC with fibromyomatous stroma, sarcomatoid RCC, and sarcomatoid clear cell RCC. Of the 4 FH-deficient RCCs, none had the classic morphology. The 5 MiT family translocation RCCs had variable morphology. There were 41 tumors without recurrence or metastases, 3 tumors with local recurrence only, 8 tumors with metastases only, and 7 tumors with both local recurrence and metastases. CONCLUSIONS The current study demonstrates the importance of special studies in accurately classifying RCC in younger individuals. The distribution of RCC subtypes in younger individuals is similar between 2 representative large institutions of the United States and Peru.

Abstract
BACKGROUND We aimed to characterize the clinical and multiphase computed tomography (CT) features, which can distinguish renal urothelial carcinoma (RUC) mimicking renal cell carcinoma (RCC) from clear cell renal cell carcinoma (ccRCC) with collecting system invasion (CSI). METHODS Data from 56 patients with RUC (46 men and 10 women) and 366 patients with ccRCC (262 men and 104 women) were collected and assessed retrospectively. The median age was 65.50 (IQR: 56.25-69.75) and 53.50 (IQR: 42.25-62.5) years, respectively. Univariate and multivariate logistic regression analyses were performed on clinical and CT characteristics to determine independent factors for distinguishing RUC and ccRCC, and an integrated predictive model was constructed. Differential diagnostic performance was assessed using the area under the receiver operating characteristic curve (AUC). RESULTS The independent predictors for differentiating RUC from ccRCC were infiltrative growth pattern, hydronephrosis, heterogeneous enhancement, preserving reniform contour, and hematuria. The differential diagnostic performance of the integrated predictive model-1 (AUC: 0.947, sensitivity: 89.07%, specificity: 89.29%) and model-2 (AUC: 0.960, sensitivity: 92.1%, specificity: 89.3%) were both better than that of the infiltrative growth pattern (AUC: 0.830, sensitivity: 71.9%, specificity: 92.9%), heterogeneous enhancement (AUC: 0.771, sensitivity: 86.3%, specificity: 67.9%), preserving reniform contour (AUC = 0.758, sensitivity: 85.5%, specificity: 66.1%), hydronephrosis (AUC: 0.733, sensitivity: 87.7%, specificity: 58.9%), or hematuria (AUC: 0.706, sensitivity: 79.5%, specificity: 51.8%). CONCLUSION The CT and clinical characteristics showed extraordinary discriminative abilities in the differential diagnosis of RUC and ccRCC, which might provide helpful information for clinical decision-making.

Abstract
BACKGROUND AND OBJECTIVE Hereditary kidney diseases (HKD) are a frequent cause of chronic kidney disease, and their diagnosis has increased since the introduction of next generation sequencing (NGS). In 2018, the Multidisciplinary Unit for Hereditary Kidney Diseases of the Region of Murcia (UMERH-RM) was founded based on the genetic study of HKD. The objective of this study is to analyze the results obtained in the first 3 years of operation, and to analyze the clinical factors associated to a final genetic diagnosis. MATERIALS AND METHODS All the patients studied with the HKD gene panel were included. The characteristics between those who obtained a final genetic diagnosis and those who did not were compared. RESULTS A total of 360 patients were studied, detecting genetic variants in 164 not related patients (45.6%). 45 of these were variants of uncertain significance requiring a family co-segregation study, which was facilitated by the multidisciplinary unit. Overall, considering the results obtained with the NGS panel and the extended genomic studies, a final diagnostic yield of HRD of 33.3% (120/360) was achieved, and including incidental findings 35.6% (128/360). Two hundred and twenty-three patients with suspected Alport syndrome were studied. Diagnosis was confirmed in 28.5% (COL4A4 most frequent gene), more frequently women with an obvious compatible family history. They also had frequently microhematuria, although 5 patients without microhematuria confirmed the diagnosis. There were no differences in age, proteinuria, renal function, hearing loss, or ophthalmologic abnormalities. The most frequent finding in the renal biopsy was mesangial proliferation. We estimate that 39 patients avoided renal biopsy. A total of 101 patients with suspected PKD were also studied, 49.5% had a conclusive genetic result (most frequent gene PKD1), more frequently women, with larger kidney sizes (although 9 patients with normal kidney size confirmed diagnosis). Again, the most predictive characteristic of genetic outcome was family history. CONCLUSIONS The implementation of an NGS panel for HKD, together with the multidisciplinary approach to cases, has improved the diagnostic performance of HKD. In our sample, autosomal dominant Alport syndrome is of highest incidence. Ophthalmological and auditory examinations did not contribute to the diagnosis. We have seen a significant decrease in the indication of renal biopsies thanks to molecular diagnosis. The multidisciplinary approach, with the active participation of nephrologists, paediatricians, clinical and molecular geneticists, with insistence on adequate patient phenotyping and review of their family history, offers a better interpretation of genetic variants, allowing reclassification of the diagnosis of some nephropathies, thus improving their management and genetic advice.

Abstract
BACKGROUND Radioactive seeds implant is a novel option in the developed world for the treatment of organ-confined prostate cancer; however, it is a rare procedure in developing countries, especially in sub-Saharan African countries like Nigeria. The first prostate brachytherapy in Nigeria was performed in 2019 at La'Newton Oncology Clinic using low-dose radioactive iodine-125. The side effects on patients that were treated in three years of its existence in Nigeria are documented in this study. OBJECTIVES This study aimed to narrate the side effects and complications of the procedure in its three years of existence in Nigeria. METHODS This was a retrospective study of the 32 eligible patients treated at the only private clinic that offers permanent radioactive iodine-125 prostate seeds implant in Nigeria. The patients were followed-up for 24 months. The biodata, urinary symptoms and erectile function were analyzed using the medical records, a detailed expanded prostate cancer index composite questionnaire, and a modified Radiation Therapy Oncology Group Grading System. RESULT It was noticed that the burning sensation at the perineum, which was self-limiting within 72 hours, was a major complaint among all the subjects. All the patients experienced haematuria; 74% of the subjects noted that the haematuria resolved within 12 hours post-implant, while it resolved within 24 hours for the remaining 26%. Acute urinary retention occurred in one subject. The EPIC scoring system showed that only one subject lost the ability to have a firm erection adequate for sexual intercourse. There was no gastrointestinal toxicity recorded among the participants. CONCLUSION The side effects observed among the subjects were negligible compared to conventional surgery, so this procedure should be considered in all cases of organ-confined prostate cancer, especially as it is also cost-effective.

Abstract
BACKGROUND Drug-mediated immune hemolysis is a rare but potentially life-threatening condition. Based on a case of penicillin-induced immune hemolysis, a structured literature review of case reports and studies on penicillin-mediated Drug-Induced Immune Hemolytic Anemia (DIIHA) was carried out. CASE REPORT A 28-year-old male patient presented to the emergency department with gross hematuria and non-specific abdominal complaints. The patient had a 10-day history of respiratory infection with bacterial tonsillitis, treated orally with penicillin V on an outpatient basis. Laboratory diagnostics detected pathologically altered direct and indirect hemolysis parameters. After stopping the medication, the patient's condition could be stabilized. CONCLUSION Diagnosis of penicillin-mediated immune hemolysis requires structured cooperation between clinic and laboratory, as clinical and serological findings may be highly variable with the risk of misdiagnosis. Due to the rarity of the disease, this case report is intended to raise awareness with respect to the triad of abrupt drop in hemoglobin levels in connection with drug therapy and in combination with a strongly positive direct Coombs test.

Abstract
OBJECTIVES The aim of study was to evaluate the diagnostic utility of the renal parenchyma elasticity with the shear wave elastography (SWE) and microvascularization with the superb microvascular imaging (SMI) technique before kidney biopsy and to predict the complication of hemorrhage before kidney biopsy. METHODS A total of 75 patients were included in the prospective study. Before the biopsy, vascularity features of the kidney parenchyma in the area to be biopsied were assessed by SMI and parenchymal stiffness by SWE and were examined by 2 independent radiologists. RESULTS A statistically significant difference was found in the SMI and SWE values between the groups with and without hematoma and hematuria when compared with the Student t test and Mann-Whitney U test ( P < 0.05). The SWE hardness cutoff value, which maximizes the prediction of the development of hematuria, was found to be 18.40 kPa, and the sensitivity and specificity values were 84.4% and 62.8%, respectively. In SMI vascularity index values, the cutoff value was found to be 0.247410800 kPa, and sensitivity and specificity values were 81.3% and 83.7%, respectively. The cutoff value of the SMI vascularity index values that maximized the prediction of hematoma development was 0.297009650, and the sensitivity and specificity values were 87% and 87%, respectively. CONCLUSIONS We believe that evaluating and standardizing the microvascularization and elasticity of the kidney parenchyma before a percutaneous kidney biopsy will be potentially useful as a guiding method in the prediction of postbiopsy hemorrhage development.

Abstract
The urothelium is a vital permeability barrier that prevents the uncontrolled flow of urinary components into and out of the bladder interstitium. Our study addressed the question of possible sex-specific variations in the urothelium of healthy mice and their impact on chronic bladder inflammation. We found that healthy female bladders have a less robust barrier function than male bladders, as indicated by significant differences in transepithelial electrical resistance (TEER) values. These differences could be attributed to detected higher claudin 2 mRNA expression and a less pronounced glycocalyx in females than in males. In addition, TEER measurements showed delayed barrier recovery in chronically inflamed female bladders. We found subtle differences in the expressions of genes involved in the regulation of the actin cytoskeleton between the sexes, as well as pronounced urothelial hyperplasia in females compensating for attenuated barrier function. The identified genetic variations in glycosylation pathways may also contribute to this divergence. Our findings add to the growing body of literature on the intricate sex-specific nuances of urothelial permeability function and their implications for chronic bladder inflammation. Understanding these differences could lead to tailored diagnostic and therapeutic approaches in the treatment of bladder disorders in the future.

Abstract
INTRODUCTION While the use of different immunosuppressants has been investigated in immunoglobulin A nephropathy, further investigation is needed to assess the effect of a regimen of mycophenolate mofetil combined with a short course of glucocorticosteroids in the subset of patients with histologically active features. We compared the efficacy and safety of a combined regimen of mycophenolate mofetil and glucocorticosteroids to a conventional regimen of glucocorticosteroids alone in patients with immunoglobulin A nephropathy who have active lesions and major urinary abnormalities. METHODS This retrospective study involved 30 immunoglobulin A nephropathy patients with active histological lesions, 15 of whom were treated with both mycophenolate mofetil 2 g/day for 6 months and 3 pulses of 15 mg/kg methylprednisolone, followed by a short tapering schedule of oral prednisone. The control group was made up of the remaining 15 clinically- and histologically-matched patients treated with glucocorticosteroids alone according to a validated schedule, i.e., 1 g of methylprednisolone given intravenously for 3 consecutive days, followed by oral prednisone 0.5 mg/kg every other day for 6 months. At diagnosis, all patients had urinary protein excretion > 1 g/24 h and microscopic hematuria. RESULTS At the end of the first year of follow-up (30 patients) and after 5 years (17 patients), there were no differences between the two groups in terms of urinary abnormalities and functional parameters. Both regimens achieved a statistically significant decrease in 24-h urinary protein excretion (p < 0.001) and a reduction of microscopic hematuria. However, the mycophenolate mofetil-based regimen allowed a cumulative sparing dose of 6 g of glucocorticosteroids. CONCLUSION In this single center study on immunoglobulin A nephropathy patients with active lesions and major urinary abnormalities and at increased risk of glucocorticosteroid-related complications, a mycophenolate mofetil-based regimen demonstrated similar outcomes in terms of complete response and relapse (at 1 and 5 years) compared to a conventional glucocorticosteroid-based protocol, while achieving a consistent reduction of glucocorticosteroid cumulative dose.

Abstract
BACKGROUND Hematuria is common in myeloperoxidase anti-neutrophil cytoplasmic antibody associated vasculitis (ANCA-MPO). Previous studies have mainly focused on urinary dysmorphic red blood cells and few have reported the clinical significance of isomorphic urinary red blood cells. Therefore, the main aim of this study was to assess the predictive yield of urinary isomorphic red blood cells for disease severity and renal outcomes in patients with ANCA-MPO associated vasculitis. METHODS A total of 191 patients with ANCA-MPO associated vasculitis with hematuria were retrospectively selected and were divided into two groups (with isomorphic red blood cells versus dysmorphic red blood cells) according to the percentage of isomorphic red blood cells on urinary sediment analysis. Clinical, biological and pathological data at diagnosis were compared. Patients were followed up for a median of 25 months and progression to end-stage kidney disease and death were regarded as main outcome events. Additionally, univariate and multivariate Cox regression models were used to estimate the risk factors for end-stage kidney disease. RESULTS Out of 191 patients, 115 (60%) had ≥ 70% and 76 (40%) had < 30% urine isomorphic red blood cells. Compared with patients in the dysmorphic red blood cell group, patients in the isomorphic red blood cell group had a significantly lower estimated glomerular filtration rate (eGFR) [10.41 mL/min (IQR 5.84-17.06) versus 12.53 (6.81-29.26); P = 0.026], higher Birmingham Vasculitis Activity Score [16 (IQR 12-18) versus 14 (10-18); P = 0.005] and more often received plasma exchange [40.0% versus 23.7% (P = 0.019)] at diagnosis. Kidney biopsies revealed a higher proportion of patients with glomerular basement membrane fracture in the isomorphic red blood cell group [46.3% versus 22.9% (P = 0.033)]. Furthermore, patients with predominant urinary isomorphic red blood cells were more likely to progress to end-stage kidney disease [63.5% versus 47.4% (P = 0.028)] and had a higher risk of death [31.3% versus 19.7% (P = 0.077)]. The end-stage kidney disease-free survival was lower in patients in the isomorphic red blood cell group (P = 0.024). However, urine isomorphic red blood cells ≥ 70% could not predict the presence of end-stage kidney disease in multivariate Cox analysis. CONCLUSION Myeloperoxidase-anti-neutrophil cytoplasmic antibody associated vasculitis patients with predominant urinary isomorphic red blood cells at diagnosis had more severe clinical manifestations and a higher risk of poor renal outcomes. In this respect, urinary isomorphic red blood cells could be viewed as a promising biomarker of ANCA_MPO vasculitis severity and progression.

Abstract
BACKGROUND The best treatment for IgAN is still debated. The trials NEFIGAN and NEFIGARD have demonstrated that TRF-budesonide (Nefecon) efficiently and safely reduced proteinuria in adults, leading to FDA approval of Nefecon for adult IgAN. In pediatric IgAN, an etiological treatment does not yet exist, and the main therapies remain RAAS inhibitors and oral steroids. To our knowledge, this is one of the few pediatric reports of TRF-budesonide therapy. CASE REPORT-DIAGNOSIS/TREATMENT A 13-year-old boy underwent a kidney biopsy for recurrent macrohematuria and proteinuria, resulting in an IgAN diagnosis (MEST-C score M1-E1-S0-T0-C1). At admission, serum creatinine and UPCR were slightly increased. Three methylprednisolone pulses were performed, followed by prednisone and RAAS inhibitors therapy. However, after 10 months, macrohematuria became constant, and UPCR increased. A new kidney biopsy was performed, showing an increase in sclerotic lesions. Prednisone was discontinued, and a trial with IBD TRF-budesonide 9 mg/day started. One month later, macrohematuria episodes disappeared and UPCR decreased, with a stable kidney function. After 5 months, due to a reduction in morning cortisol levels and difficulty in drug provisioning, we started to wean TRF-budesonide by 3 mg every 3 months, with complete withdrawal after 1 year. During this period, episodes of macrohematuria dramatically decreased, and UPCR and kidney function were maintained stable. CONCLUSION Our case demonstrates that TRF-budesonide could be considered an effective second-line treatment in pediatric IgAN, particularly when a long course of steroids is necessary to control active inflammation. However, pediatric clinical trials to identify the correct dosage and tolerability of TRF-budesonide are urgently needed.

Abstract
BACKGROUND Emphysematous cystitis is a rare urologic condition typically characterized by abdominal pain, hematuria, and dysuria. In some cases, complications such as bladder rupture, necrosis, and septic shock have been reported. Emphysematous cystitis has been associated with several predisposing medical conditions, such as diabetes mellitus, recurrent urinary tract infections, and immunosuppression, but can also infrequently present in an undifferentiated fashion without these aforementioned risk factors, such as in our patient's case. CASE REPORT We describe a rare case of emphysematous cystitis in a 67-year-old woman presenting to the Emergency Department with hematuria. The patient's presenting symptoms also included severe lower abdominal pain and dysuria. Examination revealed suprapubic tenderness and gross hematuria. Imaging revealed gas within the bladder lumen and throughout the bladder wall. Radiography showed concerns for emphysematous cystitis, without evidence of bladder fistula formation with adjacent bowel loops or cysto-vaginal fistula. After consultation with the Urology Department, the patient was admitted for serial examinations, intravenous antibiotics, and continued monitoring. The patient was discharged in good condition after a 3-day hospitalization. CONCLUSIONS Clinicians evaluating patients for acute urologic symptoms should be alert to the possible diagnosis of emphysematous cystitis, given the potential for deterioration and concomitant complications. Although our patient's presentation included no traditional risk factors for emphysematous cholecystitis, she required hospitalization to ensure progressive improvement. Therefore, prompt management along with appropriate consultation with specialists are crucial to mitigate the risk of adverse outcomes in this rare urologic emergency.

Abstract
BACKGROUND Clopidogrel and ticagrelor are rarely reported to cause vasculitis via drug hypersensitivity reaction, largely mediated by T cells and immunoglobulin E (IgE). Despite therapeutic advances, the etiology of refractory vasculitides remains incompletely understood. Recently, (non)immunological mechanisms bypassing T cells and IgE have been proposed to explain resistance to standard immunosuppressants. Herein, we report a case of refractory drug-induced systemic small-vessel vasculitis with varied extracutaneous manifestations and incorporate multiple sources of data to provide detailed accounts of complex (non)immunological phenomena involved in this case. Study objectives are to provide an insight about rare presentations of commonly used drugs, upgrade the pathophysiological concepts of drug-induced vasculitis, raise need for further investigation to define causes and risk factors for refractory vasculitis, and discuss most of the current knowledge suggesting novel therapeutic approaches to treat this vasculitis. To our knowledge, this is the first case of the two flares of systemic small-vessel vasculitis in a single patient in response to clopidogrel and ticagrelor exposure, respectively. However, this report is limited by attribution/observer bias. CASE PRESENTATION We herein report a 24-year-old Caucasian male student with a medical history of mild seasonal allergic rhinoconjunctivitis, tension-type headaches, posttraumatic arterial stenosis, and previous exposure to ibuprofen, acetylsalicylic acid, and mRNA coronavirus disease 2019 (COVID-19) vaccine who suffered largely from acute urticaria and dyspnea after 20 days of acetylsalicylic acid and clopidogrel introduction. A skin punch biopsy confirmed leukocytoclastic vasculitis. Serologic antibody testing, complement analysis, microbiologic testing, and cancer biomarkers revealed no abnormalities. Regarding the patient's medical history, both acetylsalicylic acid and clopidogrel were exchanged for ticagrelor. Furthermore, the addition of naproxen, cyclosporine, bilastine, prednisolone, and montelukast resulted in complete recovery. After 7 days, diarrhea and hematuria occurred. Urinalysis and computed tomography showed reversible proteinuria with gross hematuria and hypodense changes in kidney medulla, respectively, associated with discontinuation of ticagrelor and naproxen. In addition, the patient recovered completely without any immunosuppression up-titration. CONCLUSIONS This case highlights the role of clopidogrel and ticagrelor as possible triggering agents for systemic small-vessel vasculitis and offers an insight into novel therapeutic strategies for refractory vasculitides. Further research is needed to build on the findings of a current report.

Abstract
RATIONALE Dengue fever is a widespread mosquito-borne viral disease, most prevalent in the tropical and subtropical areas of the world. There has been a significant rise in the incidence and number of outbreaks of dengue in recent years, which has made it a matter of global concern. It may be associated with a number of renal complications, ranging from hematuria, proteinuria, glomerulonephritis, and acute tubular necrosis. However, renal cortical necrosis (RCN) is a rare renal complication of this disease. PATIENTS CONCERNS We report the case of a young gentleman who presented with fever, vomiting, and anuria. On workup, he was found to be having complicated Dengue fever with RCN resulting in acute renal failure. DIAGNOSIS To the best of our knowledge, RCN is not a reported renal complication of dengue fever. INTERVENTIONS AND OUTCOMES Our report highlights the importance of early consideration of renal cortical necrosis in patients with dengue fever and persistent anuria. LESSON This would allow for better disease prognostication while enabling physicians to develop more effective treatment strategies.

Abstract
This study aimed to develop and validate a combined nomogram model based on superb microvascular imaging (SMI)-based deep learning (DL), radiomics characteristics, and clinical factors for noninvasive differentiation between immunoglobulin A nephropathy (IgAN) and non-IgAN.We prospectively enrolled patients with chronic kidney disease who underwent renal biopsy from May 2022 to December 2022 and performed an ultrasound and SMI the day before renal biopsy. The selected patients were randomly divided into training and testing cohorts in a 7:3 ratio. We extracted DL and radiometric features from the two-dimensional ultrasound and SMI images. A combined nomograph model was developed by combining the predictive probability of DL with clinical factors using multivariate logistic regression analysis. The proposed model's utility was evaluated using receiver operating characteristics, calibration, and decision curve analysis. In this study, 120 patients with primary glomerular disease were included, including 84 in the training and 36 in the test cohorts. In the testing cohort, the ROC of the radiomics model was 0.816 (95% CI:0.663-0.968), and the ROC of the DL model was 0.844 (95% CI:0.717-0.971). The nomogram model combined with independent clinical risk factors (IgA and hematuria) showed strong discrimination, with an ROC of 0.884 (95% CI:0.773-0.996) in the testing cohort. Decision curve analysis verified the clinical practicability of the combined nomogram. The combined nomogram model based on SMI can accurately and noninvasively distinguish IgAN from non-IgAN and help physicians make clearer patient treatment plans.

Abstract
BACKGROUND Acute post-streptococcal glomerulonephritis (APSGN) is common in developing countries with a high hospitalization rate. Most patients have acute nephritic syndrome features, although some occasionally present with unusual clinical features. This study aims to describe and analyze clinical features, complications, and laboratory parameters in children diagnosed with APSGN at presentation, 4 and 12 weeks later, in a resource-limited setting. METHODS This cross-sectional study was conducted among children < 16 years with APSGN between January 2015 and July 2022. Hospital medical records and outpatient cards were reviewed for clinical findings, laboratory parameters, and kidney biopsy results. Descriptive analysis of multiple categorical variables was performed using SPSS version 16.0 and presented as frequencies and percentages. RESULTS The study included 77 patients. Most (94.8%) were older than five years, and age group 5-12 years had highest prevalence (72.7%). Boys were affected more frequently than girls (66.2% vs. 33.8%). Edema (93.5%), hypertension (87%), and gross hematuria (67.5%) were the most frequent presenting symptoms, and pulmonary edema (23.4%) was the most common severe complication. Anti-DNase B and anti-streptolysin O titers were positive in 86.9% and 72.7%, respectively, and 96.1% had C3 hypocomplementemia. Most clinical features resolved in three months. However, at 3 months, 6.5% of patients had persistent hypertension, impaired kidney function, and proteinuria alone or in combination. Most patients (84.4%) had an uncomplicated course; 12 underwent kidney biopsy, 9 required corticosteroids, and 1 required kidney replacement therapy. There was no mortality during the study period. CONCLUSION Generalized swelling, hypertension, and hematuria were most common presenting features. Persistent hypertension, impaired kidney function, and proteinuria persisted in a small proportion who had a significant clinical course and required kidney biopsy. A higher resolution version of the Graphical abstract is available as Supplementary information.

Abstract
OBJECTIVES To compare the efficacy and safety of shockwave lithotripsy (SWL) using a narrow focus or wide focus for renal stones. PATIENTS AND METHODS A double-blind randomised trial included adult patients with a solitary radio-opaque renal pelvic stone of 1-2 cm. Patients were randomised into two groups: narrow-focus (2 mm) SWL and wide-focus (8 mm) SWL. The stone-free rate (SFR) and presence of complications such as haematuria, fever, pain, and peri-renal haematoma were evaluated. Pre- and postoperative urinary markers (neutrophil gelatinase-associated lipocalin [NGAL] and kidney injury molecule 1 [KIM-1]) concentrations were compared to assess renal injury. RESULTS A total of 135 patients were recruited for this study. The SFR after the first SWL session was 79.2% and 69.1% in narrow- and wide-focus groups, respectively. There was a comparable rise in the median 2-h NGAL concentration in both groups (P = 0.62). However, the rise in the median (interquartile range [IQR]) 2-h KIM-1 concentration was significantly higher in the narrow-focus group at 4.9 (4.6, 5.8) ng/mL compared with the wide-focus group at 4.4 (3.2, 5.7) ng/mL (P = 0.02). Nevertheless, the 3-day NGAL and KIM-1 urinary marker concentrations were significantly improved (P = 0.263 and P = 0.963, respectively). The overall SFR after three sessions was 86.6% and 86.8% in the narrow- and wide-focus groups, respectively (P = 0.77). Both groups were comparable for complications, apart from the median pain score and the percentage of high-grade haematuria, which were significantly higher in the narrow-focus group (P < 0.001 and P = 0.03, respectively). CONCLUSION Narrow- and wide-focus SWL were associated with comparable outcomes and re-treatment rates. However, narrow-focus SWL was associated with significantly higher morbidity in terms of pain and haematuria.

Abstract
BACKGROUND Currently, the clinical strategy for diagnosis of non-muscle invasive bladder cancer (NMIBC) such as cystoscopy and cytology are invasive and/or with limited accuracy. OncoUrine, a urinary assay for mutation and methylation biomarkers, have showed a high accuracy in the detection of upper tract urinary carcinoma (UTUC) patients with hematuria. The aim of this study is to evaluate the performance of OncoUrine in diagnosis of NMIBC patients. METHODS In this multicenter prospective study, a total of 203 patients were enrolled, including 60 patients present with hematuria and 143 NMIBC patients under recurrence surveillance. Urine samples were collected before cystoscopy to undergo OncoUrine test. OncoUrine performance was calculated compared to clinical standard methods in hematuria cohort and recurrence surveillance cohort, respectively. Furthermore, NMIBC patients were followed up with a median time of 20.5 months (range 0.03 to 24.03 months) to assess the predictive value of OncoUrine during recurrence monitoring. RESULTS For bladder cancer diagnosis, OncoUrine tested 47 samples and achieved a sensitivity/specificity/positive predictive value (PPV)/negative predictive value (NPV) of 80% (95% CI 44.2-96.5)/91.9% (95% CI 77.0-97.9)/72.7% (95% CI 39.3-92.7)/94.4% (95% CI 80.0-99.0) (kappa value 69.4%, 95% CI 44.4-94.3), indicating 72.3% of unnecessary cystoscopy. For recurrence diagnosis, OncoUrine tested 93 samples, and the sensitivity/specificity/PPV/NPV was 100% (95% CI 59.8-100.0)/68.2% (95% CI 57.1-77.7)/22.9% (95% CI 11.0-40.6)/100% (95% CI 92.3-100.0) (kappa value 27.0%, 95% CI 11.1-42.8), indicating 62.4% of spared cystoscopy. What is more, OncoUrine correctly predicted 80% (20/25) of final recurrence with 12/25 (48%) patients who were OncoUrine positive, but cystoscopy negative was followed with recurrence during follow-up. The test result of OncoUrine was also found significantly correlated with recurrence free survival (RFS) of NMIBC patients (median 34.4-month vs unreached; HR 6.0, 95% CI 2.7-13.5, P < 0.0001). CONCLUSIONS OncoUrine showed potential value to reduce the frequency of unnecessary cystoscopy and the healthcare cost of bladder cancer patients. Patients with positive test results represented a population who were at high risk of recurrence and thus should be subject to frequent surveillance to ensure timely detection of any potential recurrence. This study has been registered in ClinicalTrials.gov with the number NCT04994197 posted on August 2021.

Abstract
Background: The needle size used in ultrasound-guided percutaneous renal biopsy significantly influences the efficacy and safety of the procedure. The aim of this study is to perform a comparative analysis of 16-gauge and 18-gauge needles for ultrasound-guided percutaneous renal biopsy.Methods: This systematic review and meta-analysis included randomized controlled trials and observational studies that compared the outcomes of using 18-gauge and 16-gauge needles for ultrasound-guided percutaneous renal biopsy. The efficacy parameters included a mean number of glomeruli obtained and the number of passes, while the safety parameters focused on the rate of complications. We searched multiple databases, assessed the risk of bias, and conducted statistical analyses using appropriate models.Results: Fifteen studies were included. Compared to the 18-gauge needle, the use of 16-gauge needle for the biopsy was associated with the significantly higher mean number of glomeruli obtained (pooled SMD 0.61, 95%CI: 0.32 to 0.89; p < 0.001) and fewer required passes (pooled SMD -0.57, 95%CI: -0.97 to -0.18; p = 0.004). No significant difference was observed in the individual safety parameters, including pain, hematuria, need for blood transfusion, major, and minor complications. However, the use of 16-gauge needle was associated with higher odds of total complications (pooled OR 1.57, 95%CI: 1.16 to 2.13; p = 0.004).Conclusion: While the 16-gauge needle for ultrasound-guided percutaneous renal biopsy offers improved efficacy in terms of a higher mean number of glomeruli and fewer required passes, it is associated with higher total complications. A judicious needle size selection that would consider patient-specific factors and risk-benefit ratio, is crucial for optimizing patient outcomes.

Abstract
OBJECTIVE To analyze the clinical phenotype and genetic characteristics of a patient with Alport syndrome. METHODS A patient with Alport syndrome who had visited the First Affiliated Hospital of Zhengzhou University in November 2020 was selected as the study subject. Clinical data of the patient were collected. High-throughput sequencing was carried out to detect potential variant of the COL4A3, COL4A4 and COL4A5 genes, and Sanger sequencing was carried out for verification of candidate variants in the family. RESULTS The main clinical manifestations of the patient included hematuria, proteinuria, and impaired hearing. Audiometric testing suggested symmetrical cochlear sensory neural hearing loss on both sides. Renal biopsy revealed mild mesangial proliferative glomerulonephritis. Genetic testing revealed that the patient has harbored compound heterozygous variants of the COL4A4 gene, namely c.940G>A (p.Gly314Ser) and c.3773G>A (p.Gly1258Asp), which were respectively inherited from her father and mother. Neither variant has been reported before, and were predicted to be pathogenic based on the guidelines from the American College of Medical Genetics and Genomics. CONCLUSION The c.940G>A (p.Gly314Ser) and c.3773G>A (p.Gly1258Asp) compound heterozygous variants of the COL4A4 gene probably underlay the Alport syndrome in this patient. Above finding has enriched the mutational spectrum of the COL4A4 gene.

Abstract
BACKGROUND The objective of this study was to determine the efficacy of acupuncture on the outcome of in vitro fertilization (IVF) in elderly infertile patients with kidney qi deficiency, and to explore its possible mechanism from the perspective of pseudo-targeted metabolomics of follicular fluid. METHODS Sixty cases of elderly women undergoing IVF were sampled and randomly divided into 2 equal groups: the treatment and the elderly control (HA) group. In the treatment group, routine ovulation induction combined with acupuncture treatment was used. Routine ovulation induction combined with sham acupuncture was used in the HA group. Reproductive outcomes of the 2 groups were compared. The follicular fluid of patients obtained on the day of oocyte retrieval was analyzed by the ultra-high-performance liquid chromatography-mass spectrometry analysis system. RESULTS Compared with the HA group, the score of kidney qi deficiency syndrome in the treatment group was significantly decreased, and the 2 PN fertilization rate, high-quality embryo rate and cumulative pregnancy rate were significantly increased (P < .05). Through the identification of target metabolites, 3 metabolic pathways were found to be closely related to the developmental potential of oocytes, namely: Retinol metabolism pathway; Glycine, serine, and threonine metabolism pathway; Glycerophospholipid metabolism pathway. CONCLUSION From our findings, acupuncture can improve the quality of oocytes thus bettering the outcome of IVF-assisted pregnancy in elderly patients with kidney qi deficiency.

Abstract
INTRODUCTION Around 25% of patients with bladder cancer (BCa) present with invasive disease. Non-randomised studies of population-based screening have suggested reductions in BCa-specific mortality are possible through earlier detection. The low prevalence of lethal disease in the general population means screening is not cost-effective and there is no consensus on the best strategy. Yorkshire has some of the highest mortality rates from BCa in England. We aim to test whether population screening in a region of high mortality risk will lead to a downward stage-migration of aggressive BCa, improved survival and is cost-effective. METHODS AND ANALYSIS YORKSURe is a tiered, randomised, multicohort study to test the feasibility of a large BCa screening randomised controlled trial. In three parallel cohorts, participants will self-test urine (at home) up to six times. Results are submitted via a mobile app or freephone. Those with a positive result will be invited for further investigation at community-based early detection clinics or within usual National Health Service (NHS) pathways. In Cohort 1, we will post self-testing kits to research engaged participants (n=2000) embedded within the Yorkshire Lung Screening Trial. In Cohort 2, we will post self-testing kits to 3000 invitees. Cohort 2 participants will be randomised between haematuria and glycosuria testing using a reveal/conceal design. In Cohort 3, we will post self-testing kits to 500 patients within the NHS pathway for investigation of haematuria. Our primary outcomes are rates of recruitment and randomisation, rates of positive test and acceptability of the design. The study is currently recruiting and scheduled to finish in June 2023. ETHICS AND DISSEMINATION The study has received the following approvals: London Riverside Research Ethics Committee (22/LO/0018) and Health Research Authority Confidentiality Advisory Group (20/CAG/0009). Results will be made available to providers and researchers via publicly accessible scientific journals. TRIAL REGISTRATION NUMBER ISRCTN34273159.

Abstract
BACKGROUND Early studies claimed that early congenital syphilitic (CS) nephropathy was rare, and systematic studies about this disease are absent, which may lead to poor awareness of early CS nephropathy in clinicians and result in misdiagnosis and poor patient prognosis. The present study systematically and comprehensively analyzes the clinical characteristics of infants with early CS nephropathy hospitalized in Beijing Ditan Hospital, an infectious disease hospital in China in order to improve the understanding and management of this disorder. METHODS Data of the children with early CS from July 1, 2008, to December 31, 2021, were collected from the electronic medical record system of the hospital. Each patient's demographic characteristics, clinical history, mother's history of syphilitic infection, and laboratory values were extracted. The patients were enrolled to either the nephropathy group or the non-nephropathy group depending on diagnosis. Descriptive statistics was used to report basic demographics, clinical and laboratory test values, and variables were compared between the two groups by nonparametric tests, t test or χ2 tests. RESULTS Of the 122 children with early CS enrolled, 24(19.7%) were diagnosed with early CS nephropathy. All of the children with CS nephropathy were young infants < 6 months old. A majority of them showed typical congenital syphilitic skin lesions, but a quarter of them did not have skin lesions. Compared with non-nephropathic children with early CS, those with nephropathy had higher frequency of hepatosplenomegaly, fever, edema, gastrointestinal (GI) symptoms, and anemia, as well as decreased C3 levels. Urinalysis results showed hematuria in all patients with early CS nephropathy, with proteinuria and renal function impairment in 91.7% and 12.5% of the patients, respectively. Nephritic-type nephrotic syndrome and glomerulonephritis were diagnosed in 45.8% and 54.2% of these patients, respectively. All infants with CS nephropathy were cured or improved after appropriate treatments. CONCLUSION Infants with early CS nephropathy often presented with nephritic-type nephrotic syndrome or glomerulonephritis, and the typical skin lesions, fever, hepatosplenomegaly, and edema, etc., were its common clinical presentations, and these characteristics could help with the diagnosis. But for infants with nephropathy who did not have typical clinical presentations, CS should also be screened as an important etiology to avoid misdiagnosis.

Abstract
OBJECTIVES An increasing number of urologists is switching from transrectal (TR) to transperineal (TP) biopsy procedures for the diagnosis of prostate cancer. Local anesthesia (LA) might be advantageous in terms of patient management, risks and costs. We aimed to evaluate the tolerability and complication rates of TP prostate biopsy performed under LA. METHODS This is a monocentric, prospective, comparative, observational cohort study. Between July 2020 and July 2021 we included 128 consecutive patients (TR, n = 61; TP, n = 67), with a suspicion of prostate cancer. Transrectal vs. transperineal prostate biopsies were both performed under LA. To evaluate the tolerability we administered a validated visual analog pain score (VAS) during the different steps of the biopsy procedure as well as at 12-, 24- and 48-hours post procedure. The International Prostate Symptom Score (IPSS) questionnaire was administered before the procedure and at the same time intervals. The presence of hematuria, hematospermia, rectal blood loss, acute retention and febrile urinary tract infection (UTI) were also monitored. RESULTS There were no significant differences in pain or IPSS between groups, except for a significantly higher pain score during the LA of the prostate in the TP group. In general, complication rates were similar, only the prevalence of hematuria at 24 hours was significantly higher in the TP group, as was rectal blood loss at 12 hours postprocedure in the TR group. CONCLUSIONS In conclusion, our study showed that transperineal prostate biopsy under local anesthesia could be performed with similar pain scores and complication rates, compared to the transrectal procedure.

Abstract
OBJECTIVE Clinical evaluation of systemic lupus erythematosus (SLE) disease activity is limited and inconsistent, and high disease activity significantly, seriously impacts on SLE patients. This study aims to generate a machine learning model to identify SLE patients with high disease activity. METHOD A total of 1014 SLE patients with low disease activity and 453 SLE patients with high disease activity were included. A total of 94 clinical, laboratory data and 17 meteorological indicators were collected. After data preprocessing, we use mutual information and multisurf to evaluate and select the importance of features. The selected features are used for machine learning modeling. Performance of the model is evaluated and verified by a series of binary classification indicators. RESULTS We screened out hematuria, proteinuria, pyuria, low complement, precipitation, sunlight and other features for model construction by integrated feature selection. After hyperparameter optimization, the LGB has the best performance (ROC: AUC = 0.930; PRC: AUC = 0.911, APS = 0.913; balance accuracy: 0.856), and the worst is the naive bayes (ROC: AUC = 0.849; PRC: AUC = 0.719, APS = 0.714; balance accuracy: 0.705). Finally, the selection of features has good consistency in the composite feature importance bar plot. CONCLUSION We identify SLE patients with high disease activity by a simple machine learning pipeline, especially the LGB model based on the characteristics of proteinuria, hematuria, pyuria and other feathers screened out by collective feature selection.

Abstract
Glomerulonephritis (GN) encompasses several disorders that cause glomerular inflammation and injury through an interplay of immune-mediated mechanisms, host characteristics, and environmental triggers, such as infections. GN can manifest solely in the kidney or in the setting of a systemic illness, and presentation can range from chronic and relatively asymptomatic hematuria to fulminant renal failure. Classic acute GN is characterized by hematuria, edema, and hypertension, the latter 2 of which are the consequence of sodium and water retention in the setting of renal impairment. Although presenting signs and symptoms and a compatible clinical history can suggest GN, serologic and urinary testing can further refine the differential diagnosis, and renal biopsy can be used for definitive diagnosis. Treatment of GN can include supportive care, renin-angiotensin-aldosterone system blockade, immunomodulatory therapy, and renal transplant. Prognosis is largely dependent on the underlying cause of GN and can vary from a self-limited course to chronic kidney disease. This review focuses on lupus nephritis, IgA nephropathy, IgA vasculitis, and postinfectious GN.

Abstract
OBJECTIVE To investigate whether hematuria is a risk factor in IgA nephropathy (IgAN) patients with mild proteinuria and well-preserved renal function. METHODS This retrospective study included a total of 63 IgAN patients, with complete clinical data available for 50 patients. Hematuria assessment was conducted using two methods: 1) an automated method using a urine particle analyzer, and 2) a manual method performed by a skilled examiner to examine microscopic urine sediment. RESULTS The results of hematuria measurement using both automated and manual methods showed a strong linear correlation (r = 0.78, P < 0.001). In IgAN patients, those with high urinary red blood cell count (U-RBCs) exhibited higher serum IgA levels compared to patients with low U-RBCs. Additionally, patients with crescent formation had higher levels of proteinuria compared to those without crescents. Patients who received immunosuppressive treatment displayed higher levels of systolic blood pressure (SBP) and mean arterial pressure (MAP), as well as lower levels of serum hemoglobin and albumin. They also had a higher prevalence of T1 lesions compared to patients who did not undergo immunosuppression. Furthermore, among patients with crescent formation, those who received immunosuppressive agents exhibited higher levels of SBP, diastolic blood pressure (DBP), MAP, and U-RBCs, as well as lower levels of albumin and proteinuria at the time of renal biopsy. No composite kidney endpoint events were observed in these groups of patients. The U-RBCs level was not identified as a risk factor influencing the decline of estimated glomerular filtration rate (eGFR) in IgAN. CONCLUSIONS The presence of hematuria at the time of biopsy was not found to be associated with kidney disease progression in IgAN patients who had mild proteinuria and well-preserved renal function. This suggests that it is possible that these patients may not derive significant benefits from immunosuppressive therapy.

Abstract
BACKGROUND Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has a remarkable kidney tropism. While kidney effects are common in severe coronavirus disease 2019 (COVID-19), data on non-severe courses are limited. Here we provide a multilevel analysis of kidney outcomes after non-severe COVID-19 to test for eventual kidney sequela. METHODS This cross-sectional study investigates individuals after COVID-19 and matched controls recruited from the Hamburg City Health Study (HCHS) and its COVID-19 program. The HCHS is a prospective population-based cohort study within the city of Hamburg, Germany. During the COVID-19 pandemic the study additionally recruited subjects after polymerase chain reaction-confirmed SARS-CoV-2 infections. Matching was performed by age, sex and education. Main outcomes were estimated glomerular filtration rate (eGFR), albuminuria, Dickkopf3, haematuria and pyuria. RESULTS A total of 443 subjects in a median of 9 months after non-severe COVID-19 were compared with 1328 non-COVID-19 subjects. The mean eGFR was mildly lower in post-COVID-19 than non-COVID-19 subjects, even after adjusting for known risk factors {β = -1.84 [95% confidence interval (CI) -3.16 to -0.52]}. However, chronic kidney disease [odds ratio (OR) 0.90 (95% CI 0.48-1.66)] or severely increased albuminuria [OR 0.76 (95% CI 0.49-1.09)] equally occurred in post-COVID-19 and non-COVID-19 subjects. Haematuria, pyuria and proteinuria were also similar between the two cohorts, suggesting no ongoing kidney injury after non-severe COVID-19. Further, Dickkopf3 was not increased in the post-COVID-19 cohort, indicating no systematic risk for ongoing GFR decline [β = -72.19 (95% CI -130.0 to -14.4)]. CONCLUSION While mean eGFR was slightly lower in subjects after non-severe COVID-19, there was no evidence for ongoing or progressive kidney sequela.

Abstract
BACKGROUND The majority of cases of Dent's disease are caused by pathogenic variants in the CLCN5 gene, which encodes a voltage-gated chloride ion channel (ClC-5), resulting in proximal tubular dysfunction. We present three members of the same family and one unrelated paediatric patient with the same insertion-deletion CLCN5 variant. The identification of these patients and positive familial segregation led to the re-classification of this variant from one of unknown significance to one of likely pathogenicity. CASE PRESENTATION A 41 year old male presented with end stage kidney failure, proteinuria and haematuria. Whole genome sequencing identified an insertion-deletion variant in CLCN5, resulting in a missense change (c.1744_1745delinsAA p.(Ala582Lys)). His brother and nephew, who both exhibited renal impairment, haematuria, proteinuria, glycosuria and nephrocalcinosis, were found to have the same variant. In addition, genetic testing of an unrelated paediatric patient who presented with proteinuria and hypercalciuria, demonstrated the same variant. CONCLUSIONS The identification of this novel variant in four individuals with features of Dent's disease, has led to the re-classification of the variant to one of likely pathogenicity. As a result, our patients and any future patients with the same variant can be offered a likely diagnosis, without the need for kidney biopsy, and their family members can be offered genetic screening.

Abstract
OBJECTIVES To investigate the clinical characteristics, pathology, and prognosis of children with diffuse endocapillary proliferative Henoch-Schönlein purpura nephritis (DEP-HSPN). METHODS A retrospective analysis was performed on the clinical, pathological, and prognosis data of 44 children with DEP-HSPN and 765 children without DEP-HSPN. The children with DEP-HSPN were diagnosed by renal biopsy in Jiangxi Provincial Children's Hospital from January 2006 to December 2021. RESULTS Among the 809 children with purpura nephritis, 44 (5.4%) had DEP-HSPN, with a mean age of (8±3) years, and there were 29 boys (65.9%) and 15 girls (34.1%). Compared with the non-DEP-HSPN group, the DEP-HSPN group had a significantly shorter time from onset to renal biopsy and a significantly higher proportion of children with respiratory infection or gross hematuria, and most children had nephrotic syndrome. The DEP-HSPN group had significantly higher levels of 24-hour urinary protein, urinary protein grading, microscopic hematuria grading, serum creatinine, and blood urea nitrogen and significantly lower levels of serum albumin and complement C3 (P<0.05). The DEP-HSPN group had a higher pathological grading, with predominant deposition of IgA in the mesangial area and capillary loops, and higher activity scores in the modified semi-quantitative scoring system (P<0.05). The Kaplan-Meier survival analysis showed that there was no significant difference in the renal complete remission rate between the two groups (P>0.05). CONCLUSIONS Children with DEP-HSPN have a rapid onset, severe clinical manifestations and pathological grading, and high activity scores in the modified semi-quantitative scoring system. However, most of the children with DEP-HSPN have a good prognosis, with a comparable renal complete remission rate to the children without DEP-HSPN.

Abstract
BACKGROUND Clear cell renal cell carcinoma (ccRCC) constitutes the most frequently encountered sporadic class of kidney cancer in adults. Recently, a rare form of clear cell kidney cancer known as ccRCC with hemangioblastoma-like features was proposed, with unique immunological characteristics and a good prognosis. The tumor expressed alpha-inhibin and carbonic anhydrase Ⅸ (CA9) as examined by immunohistochemistry. METHODS Herein, we report a clinical instance of ccRCC with hemangioblastoma-like features. A 49-year-old woman presenting with a chief complaint of hematuria underwent a comprehensive and meticulous assessment. Imaging findings indicated the presence of a mass in the right kidney. Subsequently, she underwent a partial nephrectomy. RESULTS Histopathological analysis of the resected specimen confirmed the presence of ccRCC with hemangioblastoma-like features. The patient was discharged from the hospital six days post-surgery and could resume her daily activities. During a one-year follow-up after surgery, no signs of recurrence were detected. CONCLUSIONS This case demonstrates the importance of including ccRCC with hemangioblastoma-like features in the differential diagnosis of renal masses in patients with hematuria, and suggests partial nephrectomy as an effective treatment modality for this rare subtype of renal cell carcinoma. However, because of the small number of reported cases and insufficient follow-up time, further investigation is necessary to determine the optimal therapeutic approach and to identify the molecular and genetic characteristics of this tumor.

Abstract
PURPOSE OR OBJECTIVE Primary sarcoma of the urinary bladder (SUB) is a rare but aggressive form of bladder cancer (BCa). Available evidence on SUB is limited to case reports and small series. The aim of the present multi-institutional study was to assess the clinical features, treatments, and outcomes of patients with SUB. MATERIALS AND METHODS Using a standardized database, 7 institutions retrospectively collected the demographics, risk factors, clinical presentation, treatment modalities and follow-up data on patients with SUB between January 1994 and September 2021. The main inclusion criteria included BCa with soft tissue tumor histology and sarcomatoid differentiation. RESULTS Fifty-three patients (38 men and 15 women) were identified. Median follow-up was 18 months (range 1-263 months). Median age at presentation was 69 years (range 16-89 years). Twenty-six percent of patients had a prior history of pelvic radiotherapy (RT), and 37% were previous smokers. The main presenting symptoms at diagnosis were hematuria (52%), pelvic pain (27%), and both hematuria and pelvic pain (10%). American Joint Committee on Cancer (AJCC) 8 th edition stage II, III and IV at diagnosis were 21%, 63% and 16%, respectively. Treatment modalities included surgery alone (45%), surgery plus neo- or adjuvant-chemotherapy (17%), surgery plus neo- or adjuvant-RT (11%), RT with concurrent chemotherapy (4%), neo-adjuvant chemotherapy plus surgery plus adjuvant RT (2%) and palliative treatment (21%). Rates of local and distant recurrences were 49% and 37%, respectively. Five-year overall survival and progression-free survival (PFS) were 66.5% and 37.6%, respectively. No statistically significant differences in PFS between the treatment modalities were observed. CONCLUSIONS Primary SUB is a heterogeneous disease group, commonly presenting at advanced stages and exhibiting aggressive disease evolution. In contrast to urothelial carcinoma, the primary pattern of recurrence of SUB is local, suggesting the need for multimodal approaches. Continuous international collaborative efforts seem warranted to provide guidance on how to best tailor treatments based on SUB-specific indices.
