Abstract
A 75-year-old man presented with macroscopic hematuria and a high serum prostate-specific antigen (PSA) level. Macroscopic hematuria had subsided by the time of consultation. The PSA level was 38.590 ng/ml, which, along with rectal examination and magnetic resonance imaging findings, led to the suspicion of prostate cancer. Transrectal needle biopsy of the prostate revealed intraductal carcinoma of the prostate (IDC-P). Computed tomography and bone scintigraphy were performed, and the prostate cancer was classified as cT2cN0M0. After 6 months of combined androgen blockade therapy, a radical prostatectomy was performed; however, PSA levels continued to increase, and the patient was diagnosed with castration resistant prostate cancer. Multiple bone metastases appeared 5 months after the initiation of abiraterone therapy. Three courses of docetaxel and two courses of cabazitaxel were administered, but the disease progression continued. The IDC-P was found to be positive for the BRCA2 mutation by BRACAnalysis® performed at the start of cabazitaxel therapy. To our knowledge, no other cases of BRCA2 mutation positive IDC-P have been reported in Japan. After we started administration of Olaparib, the patient's PSA level was lowered and the disease progression stopped.

Abstract
OBJECTIVES Abū Bakr Muḥammad ibn Zakariyyã al-Rãzî is a historical physician who made theoretical and practical contributions to medicine. The aim of al-Rãzî's book, Man lã yaḥḍuruhu al-ṭabîb, is to provide a valuable benefit to the general public. The book was written for people who do not have access to physicians, critical medical manuscripts, and medications. Our study aimed to add to the literature and discuss the issues concerning urinary tract problems in al-Rãzî's Man lã yaḥḍuruhu al-ṭabîb. MATERIALS AND METHODS The sections of al-Rãzî's Man lã yaḥḍuruhu al-ṭabîb dealing with the urinary system were discussed and translated from Arabic to English. RESULTS Urinary system problems are discussed in al-Rãzî's book under the headings of "Pains in the kidneys and bladder (nephritis and cystitis) and stones in the kidneys," "Hematuria," "Pyuria and painful micturition/dysuria," "Prescription for medicine on this subject," and "Drug for the difficulty of passing urine/strangury." The relevant sections mention drugs and approach to be used, particularly in the face of problems, rather than theoretical explanations. Changes in practice and treatment have been suggested in various symptomatic situations. CONCLUSIONS Rather than theoretical and etiological explanations for urinary problems, al-Rãzî provides accessible and applicable practical drugs and approaches for the general public, which can be considered suitable for the purpose mentioned in al-Rãzî's introduction to the book.

Abstract
BACKGROUND Renal involvement is a common and severe complication of anti-neutrophil cytoplasmic antibody-(ANCA)-associated vasculitis potentially resulting in pauci-immune necrotizing and crescentic ANCA glomerulonephritis (GN) with rapid deterioration of kidney function, progression to end stage kidney disease or, if left untreated, lethal exitus. Analysis of the urinary sediment routinely supports clinical management of ANCA GN, but histopathological implications of aberrancies in the urinary sediment mostly remain elusive. Therefore, we aimed to systematically assess the correlation of aberrancies in the urinary sediment and clinico-pathologic findings. METHODS A total of 42 kidney biopsies with ANCA GN were retrospectively analyzed in a single-center observational study. Laboratory and histopathological parameters were systematically analyzed and correlated with findings of the urinary sediment. RESULTS In the overall ANCA GN cohort, leukocyturia and hematuria were associated among each other, and with markers for non-selective glomerular damage, respectively. Non-invasive measurement of leukocyturia indicated focal (but not extensive) Bowman's capsule rupture (BCR) specifically in proteinase-3 (PR3)-ANCA GN, whereas hematuria correlated with extensive (but not focal) BCR. Concerning intrarenal immune cell infiltration, leukocyturia was associated with tubulointerstitial plasma cell infiltration in PR3-ANCA GN. Finally, none of these associations were detectable in myeloperoxidase-ANCA GN, implying different modes of kidney damage. CONCLUSION We herein expand our current knowledge by providing evidence that leukocyturia and hematuria enable non-invasive differentiation of BCR severity specifically in PR3-ANCA GN.

Abstract
Alport syndrome (AS) is a hereditary kidney disease caused by pathogenic variants in COL4A3 and COL4A4 genes with autosomal recessive or autosomal dominant transmission or in the COL4A5 gene with X-linked inheritance. Digenic inheritance was also described. Clinically it is associated with microscopic hematuria, followed by proteinuria and chronic renal insufficiency with end-stage renal disease in young adults. Nowadays, there is no curative treatment available. The inhibitors of RAS (renin-angiotensin system) since childhood slow the progression of the disease. Sodium-glucose cotransporter-2 inhibitors seem to be promising drugs from DAPA-CKD (dapagliflozin-chronic kidney disease) study, but only a limited number of patients with Alport syndrome was included. Endothelin type A receptor and angiotensin II type 1 receptor combined inhibitors, and lipid-lowering agents are used in ongoing studies in patients with AS and focal segmental glomerulosclerosis (FSGS). Hydroxychloroquine in AS is studied in a clinical trial in China. Molecular genetic diagnosis of AS is crucial not only for prognosis prediction but also for future therapeutic options. Different types of mutations will require various types of gene, RNA, or protein therapy to improve the function, the of final protein product.

Abstract
BACKGROUND IgAN is the most common primary glomerulonephritis worldwide. However, the pathogenesis of IgAN remains unknown. Currently, there is evidence that C3 deposition plays a role in disease development. This study aimed to investigate clinical, pathological features, and prognosis of adult IgAN patients with C3 deposition, as well as explore the role of complement activation in disease progression. METHODS A total of 821 patients with biopsy-proven IgAN were included in this study. Patients were divided into three different groups according to their C3 deposition intensity. Clinical and pathological characteristics were compared between groups. Logistic analysis was used to estimate the relationship between C3 deposition and the Oxford scoring system. Univariate and multivariate Cox proportional hazard regression models were used to analyze the effect of the presence of C3 deposits on the prognosis of patients with IgA nephropathy. Kaplan-Meier survival analysis was used to evaluate the cumulative incidence of renal progression between groups. RESULTS Patients with C3 deposition exhibited more severe clinical and pathological features and had a higher score according to the Oxford scoring system. With the increasing intensity of C3 deposition, patients present more hematuria, crescents, heavier interstitial inflammatory cell infiltration and a higher score on segmental sclerosis lesions. Logistic regression identified a positive relationship between C3 deposition and histopathology. Univariate and multivariate Cox regression indicated that C3 deposition was an independent risk factor for IgAN severity. The Kaplan-Meier survival curves indicated that patients with positive C3 deposition had a worse prognosis compared to those without C3 deposition. CONCLUSIONS Patients with positive glomerular C3 deposition presented with more severe clinical and histopathological characteristics and a higher score on the Oxford scoring system. With the increasing intensity of C3 deposition, IgAN patients were more likely to present with high level of microscopic hematuria, fibrous crescents, interstitial inflammatory cell infiltration, and a higher score on segmental sclerosis lesions. C3 deposition at the time of renal biopsy is likely an independent risk factor for IgA nephropathy severity and progression.

Abstract
OBJECTIVE To evaluate whether microscopic hematuria (MH) patients with a negative initial evaluation have an elevated risk for urinary carcinoma. METHODS This is a population-based retrospective study with a matched control identified 8465 adults with an MH ICD code, an initial negative urinary malignancy work-up of cystoscopy and CT urography, and at least 35 months of clinical care. 8465 hematuria naïve controls were age, gender, and smoking status matched. Subsequent coding of non-prostatic urinary cancer, or any following hematuria codes: additional microscopic unspecified or unspecified hematuria, and gross hematuria was obtained. Χ2 tests were performed. RESULTS There was no statistically significant difference in urinary malignancy rates (p > 0.05). Any urinary cancer: cases 0.74% (63/8465; 95% CI 0.58-0.95%)/controls 0.83% (71/8465; 95% CI 0.66-1.04%%) (p = 0.54); bladder: 0.45%/0.47% (p = 0.82); renal: 0.31%/0.38% (p = 0.43); ureteral: 0.01%/0.02% (p = 0.56). Subsequent gross hematuria in both males and females increased the odds of cancer: males 2.35 (p = 0.001; CI 1.42-3.91); females 4.25 (p < 0.001; CI 1.94-9.34). Males without additional hematuria had decreased odds ratio: 0.32 (p = 0.001; CI 0.16-0.64). Females without additional hematuria 0.58 (p = 0.19; CI 0.26-1.30) and both genders with additional unspecified hematuria/microscopic hematuria males 1.02 (p = 0.97; CI 0.50-2.08) and females 1.00 (p = 0.99; CI 0.38-2.66) did not have increased odds ratios (p > 0.05). CONCLUSION MH patients with initial negative evaluation have a subsequent urologic malignancy rate of less than 1% and likely do not need further urinary evaluation unless they develop gross hematuria.

Abstract
BACKGROUND Indications for kidney biopsy in adult IgA vasculitis (IgAV) remain debated and there are very few studies on this subject. The aim of this study was to establish a correlation between renal histological and clinical-laboratory data. METHODS A retrospective multicenter study was conducted using three databases from French hospitals, gathered between 1977 and 2020. The study included 294 adult patients with IgAV who had undergone kidney biopsy assessed according to the prognostic "Pillebout classification". Different statistical models were used to test the correlations between histological and clinical-laboratory data: Cochran Armitage, ANOVA, Kruskal-Wallis and logistic regression. RESULTS The patients were primarily men (64%), with a mean age of 52 years. The main organs and tissues involved were: dermatological 100%, digestive 48% and rheumatological 61%. All had features of kidney involvement. The median serum creatinine was 96 µmol/L serum albumin 35 g/L, and C-reactive protein 28 mg/L. Of the patients, 86% (n = 254) had hematuria and median proteinuria was 1.8 g/day. The only statistically significant correlation between the pathological stages and the clinical-laboratory data was the presence of hematuria (p = 0.03, 66% class I to 92% class IV). In multivariate analysis, only albuminemia was associated with extracapillary proliferation (p = 0.02; OR 0.94) and only age was associated with stages 3-4 (p = 0.03; OR 1.02). CONCLUSION Our study suggests that there is no strict baseline correlation between renal pathology and clinical-laboratory data. Given the current knowledge, it seems relevant to recommend a kidney biopsy in the presence of significant and persistent proteinuria or unexplained kidney function decline.

Abstract
Introduction Lipopolysaccharide (LPS)-accelerated autoimmune glomerulonephritis (GN) in NZBWF1 mice is a preclinical model potentially applicable for investigating lipidome-modulating interventions against lupus. LPS can be expressed as one of two chemotypes: smooth LPS (S-LPS) or rough LPS (R-LPS) which is devoid of O-antigen polysaccharide sidechain. Since these chemotypes differentially affect toll-like receptor 4 (TLR4)-mediated immune cell responses, these differences may influence GN induction. Methods We initially compared the effects of subchronic intraperitoneal (i.p.) injection for 5 wk with 1) Salmonella S-LPS, 2) Salmonella R-LPS, or 3) saline vehicle (VEH) (Study 1) in female NZBWF1 mice. Based on the efficacy of R-LPS in inducing GN, we next used it to compare the impact of two lipidome-modulating interventions, ω-3 polyunsaturated fatty acid (PUFA) supplementation and soluble epoxide hydrolase (sEH) inhibition, on GN (Study 2). Specifically, effects of consuming ω-3 docosahexaenoic acid (DHA) (10 g/kg diet) and/or the sEH inhibitor 1-(4-trifluoro-methoxy-phenyl)-3-(1-propionylpiperidin-4-yl) urea (TPPU) (22.5 mg/kg diet ≈ 3 mg/kg/day) on R-LPS triggering were compared. Results In Study 1, R-LPS induced robust elevations in blood urea nitrogen, proteinuria, and hematuria that were not evident in VEH- or S-LPS-treated mice. R-LPS-treated mice further exhibited kidney histopathology including robust hypertrophy, hyperplasia, thickened membranes, lymphocytic accumulation containing B and T cells, and glomerular IgG deposition consistent with GN that was not evident in VEH- or SLPS-treated groups. R-LPS but not S-LPS induced spleen enlargement with lymphoid hyperplasia and inflammatory cell recruitment in the liver. In Study 2, resultant blood fatty acid profiles and epoxy fatty acid concentrations reflected the anticipated DHA- and TPPU-mediated lipidome changes, respectively. The relative rank order of R-LPS-induced GN severity among groups fed experimental diets based on proteinuria, hematuria, histopathologic scoring, and glomerular IgG deposition was: VEH/CON< R-LPS/DHA ≈ R-LPS/TPPU<<< R-LPS/TPPU+DHA ≈ R-LPS/CON. In contrast, these interventions had modest-to- negligible effects on R-LPS-induced splenomegaly, plasma antibody responses, liver inflammation, and inflammation-associated kidney gene expression. Discussion We show for the first time that absence of O-antigenic polysaccharide in R-LPS is critical to accelerated GN in lupus-prone mice. Furthermore, intervention by lipidome modulation through DHA feeding or sEH inhibition suppressed R-LPS-induced GN; however, these ameliorative effects were greatly diminished upon combining the treatments.

Abstract
We herein report a case of enterocutaneous fistula in a patient with autosomal dominant polycystic kidney disease (ADPKD). A 37-year-old Japanese man was admitted to our hospital. Three months prior to transfer to our hospital, he developed intense flank pain with gross hematuria. His serum creatinine had decreased to 7.8 mg/dL and hemodialysis was started, but gross hematuria persisted and he developed hypotension. Upon admission, plain chest radiography did not reveal any free air, but computed tomography (CT) showed generalized ventral subcutaneous air from the head to the lower extremities and enlarged kidneys. Enterography showed leakage of contrast medium from the descending colon into the subcutaneous area. C-reactive protein was 23.1 mg/dL. A colostomy was placed in the transverse colon proximal to the perforation, and systemic subcutaneous drainage was performed. The fever subsequently resolved, and the C-reactive protein test became negative. Three months later, renal artery embolization was performed, and 12 months thereafter, CT showed a marked decrease in kidney size. We assume that a markedly enlarged kidney leaded to intestinal perforation, which developed into an enterocutaneous fistula. Consequently, intestinal fluid leaked into the subcutaneous cavity of the abdominal wall and spread systemically, resulting in extensive subcutaneous abscesses.

Abstract
BACKGROUND Bladder cancer is 11th most common cancer worldwide. Histologically, most of the tumors are classified as urothelial carcinomas. Less common variants (squamous cell or adenocarcinomas) usually comprise up to 10% of cases. Other types of tumors are exceptional. The finding of Ewing's sarcoma in the bladder is considered extremely rare. CASE We present the case of a 54-year-old female patient examined for painless hematuria. During the follow-up examination, a bulky tumor of the bladder was detected, but considering the extent of the bladder tumor, only a diagnostic transurethral resection was possible. According to the primary staging, the disease was already advanced at the time of admission with metastatic spread, anemia and present obstruction of the upper urinary tract. RESULTS Histologically, Ewing's sarcoma was surprisingly demonstrated in the urinary bladder. Anemia caused by hematuria and advanced disease was corrected by blood transfusions and obstruction of the right kidney by puncture nephrostomy. However, despite a very quick diagnosis, completion of staging and preparation of the patient for further treatment, the patient had died before the planned systemic treatment began. CONCLUSION The diagnosis of Ewing's sarcoma is identical to that of the other bladder tumors, i.e. transurethral resection. In the case of confirmation of this histological type, it is necessary to complete staging examinations and start multimodal treatment. Early systemic chemotherapy plays a key role and if metastatic spread is excluded, radical cystectomy or radiotherapy are included, too. The aim of our communication is to present a rare case of this disease, discuss the differential diagnosis and point out the principles and possibilities of its treatment.

Abstract
Schistosomiasis elimination has been set as a target in the Neglected Tropical Disease Roadmap of 2021 to 2030. The present study assessed the level of understanding, awareness and behaviors of schistosomiasis among students in Zanzibar and explored the influencing factors as the basis for reliable suggestions for the follow-up policy on schistosomiasis prevention and control. A Knowledge, Attitude and Practices (KAP) survey on students’ perceptions of schistosomiasis was conducted on students from grades 4−9 at two selected schools on Pemba, Zanzibar, from May through September in 2021. A total of 217 valid participants responded to the questionnaires. T-test and chi-squared tests were used to examine the association between the dependent and explanatory variables. Multiple linear regressions were used to analyze the influencing factors of KAP. The findings indicated a lack of knowledge about schistosomiasis among the participants. Although respondents were aware of the risks of infection, they continued to engage in high-risk activities. Age, family size and presence of hematuria were found as contributing factors. Elder students performed better on knowledge (p = 0.02) and attitude (p < 0.01) scores, and students with a smaller family received higher attitude scores (p = 0.04). Practice was significantly correlated with gender (p < 0.01) and hematuria (p < 0.01). Several kinds of health education should be adopted to raise students’ basic knowledge of schistosomiasis. It is also critical to make the community aware regarding schistosomiasis. Future efforts for the prevention and control of schistosomiasis should employ an integrated strategy combining communities with schools to encourage behavioral change.

Abstract
RATIONALE Epstein-Barr virus (EBV) infection is associated with a variety of diseases and can involve multiple organs and systems, with complex and nonspecific clinical manifestations that are easily misdiagnosed. Chronic EBV infection with persistent erythema multiforme (EM) on the cheek as the main manifestation is very rare and has been reported rarely. PATIENT CONCERNS This article reports a case of an adolescent female with chronic EBV infection who presented with chronic symmetrical erythema lesions on the face for 4 years, exacerbated with photophobia, lacrimation, Henoch-Schonlein purpura (HSP)-like rash, decline in granulocyte and erythrocyte lineages, hematuria, and proteinuria for 1 week. DIAGNOSES The disease was initially misdiagnosed as systemic lupus erythematosus (SLE) and later confirmed as chronic EBV infection by skin biopsy. In the case, EBV infection not only caused chronic facial EM, but also induced acute HSP and purpura nephritis (hematuria and proteinuria type). INTERVENTIONS The child was treated with 1 week of glucocorticosteroids in adequate doses combined with acyclovir antiviral therapy and 3 sessions of hemoperfusion. After discharge, she took prednisone acetate (15 mg twice a day) orally for 1 month and then discontinued. OUTCOMES She was discharged with her rash relieved and normal blood routine test and urine routine test. After 13 months of long-term follow-up, her facial erythema and hyperpigmentation became lighter, and there was no new rash on the whole body, and no abnormality in continuous monitoring of complete blood count and urine test. LESSONS This case suggests the need to be alert for chronic EBV infection in adolescent females with chronic facial EM rash and multiple organs and systems injury, in addition to connective tissue diseases such as SLE.

Abstract
OBJECTIVE To evaluate the technical success rate and complications associated with percutaneous nephrostomy (PCN) via percutaneous renal access behind the stone and renal calyx dilation in patients with complex renal stones. MATERIALS AND METHODS From January 2010 to February 2021, we identified 69 patients with 70 complex renal stones who underwent PCN. Complex renal stones were classified as simple (renal pelvis only) (27.1%, 19/70), borderline staghorn (8.6%, 6/70), partial staghorn (51.4%, 36/70), or complete staghorn (12.9%, 9/70). All PCNs were performed under ultrasound and fluoroscopic guidance using one of two renal-entry techniques: puncture behind the stone (56%, 39/70) or renal calyx dilation (44%, 31/70). Then, we retrospectively evaluated the technical success rates and complications associated with each renal entry access technique. RESULTS The overall technical success rate was 100%, and the complication rate was 20.0% (14/70). For those who underwent renal access behind the stone, the complication rate was 15.4% (6/39), and six patients (six PCNs) had transient gross hematuria. For those who underwent dilated renal calyx entry, the complication rate was 25.8% (8/31), and one patient had significant bleeding complications requiring transfusion. Furthermore, seven patients (seven PCNs) had transient gross hematuria. Overall, the complication rates did not differ between the technique groups (p = 0.279). CONCLUSION PCN for complex renal stones has a high technical success rate and an acceptable complication rate regardless of the specific technique. Renal entry behind the stone is as safe and feasible as approaching via a dilated renal calyx.

Abstract
Postinfectious glomerulonephritis (PIGN) is a leading cause of acute glomerulonephritis in children. The presentation of PIGN can vary from asymptomatic microscopic hematuria incidentally detected on routine urinalysis to nephritic syndrome and a rapidly progressive glomerulonephritis. Treatment involves supportive care with salt and water restriction, and the use of diuretic and/or antihypertensive medication, depending on the severity of fluid retention and the presence of hypertension. PIGN resolves completely and spontaneously in most children, and the long-term outcomes are typically good with preserved renal function and no recurrence.

Abstract
Radiation-induced cystitis (RIHC) is a late complication of pelvic radiation therapy defined by irritative lower urinary tract symptoms with recurrent and sometimes refractory hematuria. Conservative or endoscopic treatments are the first lines, but cystectomy in required in refractory cases. Hyperbaric oxygen therapy (HOT) has recently emerged in the management charts for recurrent and refractory hematuria. Thanks to its neoangiogenic and stem-cell stimulation properties, HOT achieves a complete resolution of hematuria in almost two third of patients and appears to be a good therapeutic alternative for this fragile population. However, its geographical availability is currently limited in Switzerland and its implementation can sometimes require long hospital stays.

Abstract
INTRODUCTION IgA nephropathy is the most common primary glomerulonephritis among adults in clinic. Thin basement membrane nephropathy is often underestimated or even omitted if it coincides with IgA nephropathy. Therefore, it is necessary to study the epidemiological, clinical, and molecular characteristics of the concurrence of this entity. METHODS Eight patients with concurrent IgA nephropathy and thin basement membrane nephropathy (IgA-T) were retrospectively analyzed based on their clinicopathological characteristics. Genetic analysis was performed using whole-exome sequencing and Sanger's sequencing. Data of the patients with IgA nephropathy and normal basement membrane (IgA-N) and variants in the local in-house database were used as controls. All candidate variants were assessed in silico. RESULTS The clinical manifestations of patients with IgA-T were hematuria, proteinuria, and renal insufficiency. Histopathological analysis showed mild mesangial hyperplasia, focal segmental glomerulosclerosis, podocyte activation, and foot process fusion. Crescent was rarely seen. COL4A and/or podocyte cytoskeleton and mitochondria-related gene variants were detected in seven IgA-T patients. Three patients exhibited pathogenic variants of COL4A, including a new variant. All IgA-T and one IgA-N patient possessed ITGB4 and/or PLEC variants, but there was no corresponding genotype-phenotype relationship. Six patients possessed other podocyte cytoskeleton and mitochondria-related gene variants such as NPHS2, SRGAP1, MYO1E, MYO1C, WT1, and COQ9, which were first reported in patients with IgA-T and were not in controls. Altogether, there were no significant differences in the degrees of proteinuria, serum creatinine, and eGFR during the follow-up period of 5-10 years, but there was a significant difference in the degree of proteinuria between IgA-T patients with podocyte-related gene variants and IgA-N patients. In the IgA-T group, patients with podocyte-related gene variants seemed predisposed to progress than patients without those variants, with higher proteinuria and serum creatinine and reduced eGFR. CONCLUSION Concurrent thin basement membrane nephropathy and/or heterozygous COL4A gene pathogenic variants do not necessarily predict the short-term progress of sporadic IgA nephropathy in adults. Predisposition factors for this disease progression should be considered for detecting the variants of COL4A and podocyte cytoskeleton and mitochondria-related genes simultaneously, which also manifests the complexity and heterogeneity of IgA nephropathy with concurrent thin basement membrane nephropathy.

Positive Predictive Factors for Urogenital Injuries in Severely Injured Patients with Pelvic and Spinal Fractures: Introducing the UPPS Scoring System. MEDICINA (KAUNAS, LITHUANIA) 2022; 58:medicina58111583. [PMID: 36363539 PMCID: PMC9695250 DOI: 10.3390/medicina58111583] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/20/2022] [Revised: 10/28/2022] [Accepted: 10/29/2022] [Indexed: 11/06/2022]
Abstract
Background and Objectives: Although urogenital injuries are common in severely injured patients, their diagnosis is often delayed. Predicting genitourinary injuries (GUI), especially in the immediate stages post injury, remains a challenge. This study aims to evaluate and determine positive predictive factors for the presence of GUI in polytrauma patients. Subsequently, these factors shall be used to develop an easy-to-use scoring system, deployable directly in the emergency setting. Materials and Methods: This study evaluates all severely injured patients with an Injury Severity Score (ISS) ≥ 16 admitted to the emergency departments of two German university hospitals between 2016 and 2020. These patients were retrospectively scanned for injuries of the thoracic and/or lumbar spine and/or the pelvic girdle. Demographic data was analyzed alongside trauma mechanism, type of injuries, mortality, length of hospital stays, surgeries, laboratory results, and urological treatment. Subgroup analysis was performed to compare patients with and without GUIs using t-tests. Conducting a binary logistic regression model, the significant factors were combined to create a scoring system, which was further analyzed for accuracy. Results: In total, 413 patients with an average ISS of 33.8 ± 15.0 were identified, and 47 patients (11.4%) sustained urogenital injuries with an average Abbreviated Injury Scale (AIS) score of 2.3 ± 1.1 (range: 1−5). The severity of the pelvic girdle injury correlated with the presence of urogenital injuries (p = 0.002), while there was no correlation with spinal injuries. Moreover, most GUIs resulted from motorcycle accidents (p < 0.001) and 87.2% of these patients were male. Patients with GUI were significantly more likely to show macrohematuria (p < 0.001) on admission and were more severely injured overall (ISS > 34). There was no significant difference in the length of intensive care unit (ICU) stay, the days until discharge, or death rates. Conclusions: Factors or circumstances which reliably predict the presence of GUI were found to include the male sex, a motorcycle accident, high severity of pelvic girdle fractures, macrohematuria on admission to the emergency department, and an ISS > 34. With these findings, we introduce the ‘Urotrauma in Polytrauma patients with Pelvic and/or Spinal injuries’ (UPPS) score for easier prediction of GUI in the emergency setting.

Abstract
Bleeding is a serious complication of percutaneous nephrolithotomy (PCNL). A rare cause of gross hematuria is a calico-venous fistula. A clinical case of successful intraoperative diagnosis and treatment of calico-venous fistula during PCNL is presented in the article. Description of a clinical case. A patient J., 53 years old, underwent examination and treatment at the Institute of Urology and Reproductive Health, FGAOU VO I.M. Sechenov First Moscow State Medical University with a diagnosis of staghorn stone of the right kidney, a stone of the left kidney, chronic right-side pyelonephritis. On June 15, 2021, mini-PCNL was performed for the staghorn stone of the right kidney. The procedure seemed to be unremarkable, but during intraoperative antegrade pyelography, the inflow of contrast agent from the lower calyxes into the posterior segmental vein of the right kidney was detected, which was managed by creating sufficient traction of the nephrostomy drainage. Communication of the collecting and venous systems of the kidney is associated with a risk of both severe gross hematuria and urine flow into the venous bed. The urine flow into the bloodstream may result in hemodynamic disturbances, up to collapse followed by cardiac arrest. In order to prevent complications of PCNL it is necessary to analyze the kidney anatomy based on three-dimensional modeling of contrast- enhanced computed tomography. A calicovenous fistula can be a source of risk of bleeding and severe complications. To minimize intraoperative damage to parenchymal structures, an analysis of three-dimensional modeling of a kidney in patients with staghorn calculus based on computed tomography is required, which allows rational planning of surgical tactics.

Abstract
OBJECTIVES Tubulointerstitial diseases is one of the common causes of renal dysfunction. Some rare pathological types are easy to be misdiagnosed and missedly diagnosed because of their low prevalence and relatively insufficient understanding, which affects the treatment and prognosis of patients. This study aims to explore clinical manifestations and pathological characteristics of several rare tubulointerstitial diseases, and therefore to improve their diagnosis and treatment. METHODS A total of 9 363 patients diagnosed by renal biopsy in the Department of Nephrology, Second Xiangya Hospital, Central South University from November 2011 to September 2021 were selected. Six cases of light chain cast nephropathy (LCCN), 2 cases of light chain proximal tubulopathy (LCPT), 1 case of LCCN with LCPT, 4 cases of genetic tubulointerstitial disease, and 6 cases of non-genetic related tubulointerstitial lesion were screened out, and their clinical manifestations and renal biopsy pathological results were collected, compared, and analyzed. RESULTS Patients with LCCN presented with mild to moderate anemia, microscopic hematuria, and mild to moderate proteinuria. Compared with patients with LCPT, proteinuria and anemia were more prominent in patients with LCCN. Five patients with LCCN and 2 patients with LCPT had elevated serum free kappa light chain. Five patients with LCCN presented clinically with acute kidney injury (AKI). Two patients with LCPT and 1 patient with LCCN and LCPT showed CKD combined with AKI, and 1 LCPT patient presented with typical Fanconi syndrome (FS). Five patients with LCCN, 2 patients with LCPT, and 1 patient with LCCN and LCPT were diagnosed with multiple myeloma. Five patients with LCCN had kappa light chain restriction in tubules on immunofluorescence and a "fractured" protein casts with pale periodic acid-Schiff (PAS) staining on light microscopy. Immunohistochemical staining of 2 LCPT patients showed strongly positive kappa light chain staining in the proximal tubular epithelial cells. And monoclonal light chain crystals in crystalline LCPT and abnormal lysosomes and different morphological inclusion bodies in noncrystalline LCPT were observed under the electron microscope. Six patients with LCCN were mainly treated by chemotherapy. Renal function was deteriorated in 1 patient, was stable in 4 patients, and was improved in 1 patient. Two patients with LCPT improved their renal function after chemotherapy. Four patients with genetic tubulointerstitial disease were clinically presented as CKD, mostly mild proteinuria, with or without microscopic hematuria, and also presented with hyperuricemia, urine glucose under normal blood glucose, anemia, polycystic kidneys. Only 1 case had a clear family history, and the diagnosis was mainly based on renal pathological characteristics and genetic testing. Compared with patients with non-genetic related tubulointerstitial lesion, patients with genetic tubulointerstitial disease had an earlier age of onset, higher blood uric acid, lower Hb and estiated glomemlar fitration (eGFR), and less edema and hypertension. Renal pathology of genetic tubulointerstitial disease presented tubular atrophy and interstitial fibrosis, abnormal tubular dilation, glomerular capsuledilation, and glomerular capillary loop shrinkage. Glomerular dysplasia and varying degrees of glomerular sclerosis were observed. Genetic tubulointerstitial disease patients were mainly treated with enteral dialysis, hypouricemic and hypoglycemic treatment. Two genetic tubulointerstitial disease patients had significantly deteriorated renal function, and 2 patients had stable renal function. CONCLUSIONS Patients with AKI or FS, who present serum immunofixation electrophoresis and/or serum free kappa light chain abnormalities, should be alert to LCCN or LCPT. Renal biopsy is a critical detection for diagnosis of LCCN and LCPT. Chemotherapy and stem cell transplantation could delay progression of renal function in patients with LCCN and LCPT. If the non-atrophic area of the renal interstitium presents glomerular capsule dilatation, glomerular capillary loop shrinkage, and abnormal tubular dilatation under the light microscopy, genetic tubulointerstitial disease might be considered, which should be traced to family history and can be diagnosed by genetic testing.

Abstract
PURPOSE We aimed to characterize the clinical and multiphase computed tomography (CT) features of the distinguishing endophytic clear cell renal cell carcinoma (ECCRCC) from endophytic renal urothelial carcinoma (ERUC). METHODS Data from 44 patients (35 men and 9 women) with ECCRCC and 21 patients (17 men and 4 women) with ERUC were retrospectively assessed. The mean patient age was 55 years (48.25- 59.50 years) and 68 years (63.00-73.00 years), respectively. Univariate and multivariate logistic regression analyses were performed to determine independent predictors for ECCRCC and to construct a predictive model that comprised clinical and CT characteristics for the differential diagnosis of ECCRCC and ERUC. Differential diagnostic performance was assessed using the area under the receiver operating characteristic curve (AUC). RESULTS The independent predictors of ECCRCC were heterogeneous enhancement (odds ratio [OR]=0.027, P=.005), hematuria (OR for gross hematuria=53.995, P=.003; OR for microscopic hematuria=31.126, P = .027), and an infiltrative growth pattern (OR=24.301, P = .022). The AUC of the predictive model was 0.938 (P < .001, sensitivity=84.10%, specificity=95.20%), which had a better diagnostic performance than heterogeneous enhancement (AUC=0.766, P=.001, sensitivity=81.82%, specificity=71.43%), hematuria (AUC=0.786, P < .001, sensitivity=81.82%, specificity=66.67%), and infiltrative growth pattern (AUC=0.748, P=.001, sensitivity=90.48%, specificity=59.09%). CONCLUSION The independent predictors, as well as the predictive model of CT and clinical characteristics, may assist in the differential diagnosis of ECCRCC and ERUC and provide useful information for clinical decision-making.

Abstract
The subset of the population that received bladder-drained allograft pancreata during peak utilization of the technique in the 1990s is approaching 20-30 postoperative years. This time frame is salient, as it parallels the time in which patients in the urologic literature develop adenocarcinomas after bladder reconstruction using gastrointestinal segments. We present the case of a 57-year-old simultaneous pancreas/kidney recipient who presented with microhematuria twenty-four years after transplantation and was found to have an adenocarcinoma of the duodenum of his failed, bladder-drained pancreas. After allograft pancreatectomy/duodenectomy, he remains disease-free eleven months postoperatively. As this patient population ages, practitioners should consider pathology of the donor duodenum and pancreas in recipients who present with gross or microscopic hematuria.
