Abstract
OBJECTIVE Ureteral stent replacement is a routine treatment for hydronephrosis in patients with cervical cancer. We developed an improved ureteral stent-change operation for hydronephrosis in cervical cancer patients and compared its outcomes with traditional stent change procedures. STUDY DESIGN Clinical data of hydronephrosis in cervical cancer patients who were admitted to our hospital from August 2014 to October 2019 were analyzed. We retrospectively reviewed 131 cervical cancer patients, out of which 43 cases included patients in the improved operation group, whereas 88 patients with hydronephrosis followed the traditional ureteral stent-change operation for ureteral obstruction. The outcomes of the two procedures were compared using the propensity score matching method. RESULTS As opposed to the traditional ureteral stent change strategy, the patients in the improved group required shorter operation time (p = 0.001) and higher success rate (p = 0.004). The FIGO stage (p = 0.046), the level of ureteral obstruction (p = 0.027), radiotherapy history (p = 0.01), stent replacement times (≤2times or > 2times) (p = 0.001), and serum creatinine level (≤200 μmol/L or > 200 μmol/L) (p < 0.001) were significantly different between the two groups before propensity score matching. Propensity score matching analysis was used to eliminate the clinical differences of 43 patients in the traditional group; however, the span of visual hematuria during the surgical complications was not included (p = 0.026) in the results. CONCLUSION An improved ureteral stent change operation is an advanced treatment option for cervical cancer patients suffering from hydronephrosis. In contrast to traditional ureteral stent change techniques, our developed strategy lowers complications such as visual hematuria but improves the success.

Abstract
RATIONALE Indwelling ureteral catheter, double J tube, or nephrostomy tube are routine procedures for percutaneous nephrolithotomy (PCNL) in children. There are a few cases in which PCNL has been performed in children without any additional instruments being left in place. PATIENT CONCERNS In this study, 3 children were treated for hematuria and complicated with different degrees of urinary tract infection. All of them were diagnosed as upper urinary tract calculi by abdominal computed tomography. DIAGNOSIS Three preschoolers were diagnosed with upper urinary tract calculi before surgery, one with no hydronephrosis and the other 2 with different degrees of hydronephrosis. INTERVENTIONS After preoperative evaluation, all the children successfully completed PCNL without indwelling ureteral catheter, double J tube, or nephrostomy tube. OUTCOMES The operation was successful and there were no residual stones observed during postoperative review. The operating times for the children were 33 minutes, 17 minutes, and 20 minutes, and the intraoperative bleeding volumes were 1 mL, 2 mL, and 2 mL. The catheter was removed on the second day after the operation, the postoperative review of the abdominal computed tomography or ultrasound did not indicate any stone residue, and there were no fever, bleeding, and other related complications after the operation. LESSONS We believe that total tubeless PCNL without artificial hydronephrosis can be achieved in the preschool population.

Abstract
INTRODUCTION This study aimed to analyze the changes in differential renal function (DRF) after laparoscopic pyeloplasty in children with high-grade hydronephrosis and factors influencing DRF improvement. METHODS We reviewed the clinical data of unilateral ureteropelvic junction obstruction (UPJO) patients with SFU grade IV who underwent laparoscopic pyeloplasty between February 2018 and October 2020. The patients were divided into two groups: DRF improvement ≥5% (group 1) and DRF improvement <5% (group 2). Preoperative, operative, and postoperative parameters were included in the statistical analysis in both groups. RESULTS A total of 29 patients with a median age of 6 months were included. The preoperative DRF in group 1 was significantly lower than that in group 2 (36.97 ± 8.47% vs. 45.19 ± 5.22%, p = 0.004). Logistic regression and receiver operating characteristic analysis showed the preoperative DRF was the predictor for renal function improvement after pyeloplasty (p = 0.021) and had a significant predictive value (p = 0.004). CONCLUSION Nearly half of the patients with high-grade UPJO had improved renal function at 1 year follow-up after laparoscopic pyeloplasty. Preoperative DRF was a predictor of renal function improvement, and postoperative functional recovery was superior in children with lower preoperative DRF.

Abstract
BACKGROUND Ureteropelvic junction obstruction is a relatively common urologic problem in children. Most cases present with pelvicaliceal dilatation in antenatal period. Historically most UPJO cases were treated with surgical procedures, but recently many of these children have been treated by nonsurgical observational plans. We compared the outcome of children with UPJO treated in surgical and observational ways. METHODS In a retrospective study, we assessed the medical history of patients diagnosed as UPJO, march 2011 to march 2021. The case definition was based on grade 3-4 hydronephrosis and obstructive pattern in dynamic renal isotopes can. Patients were put into two groups; Group 1 children were treated with a surgical procedure, and group 2 patients without any surgical procedure for at least a six months' period after diagnosis. We assessed long-term events and improvement of obstruction. RESULTS Seventy-eight children (mean age 7.32mo., 80% male) enrolled in the study, 55 patients in group one and 23 as group 2. Severe hydronephrosis was the problem of 96% of all patients significantly led to 20% in group 1 and 9% in group 2 (P < 0.001). Severe kidney involvement was observed at 91% in group 1 and 83% in group 2, decreased to 15% and 6%, respectively (P < 0.001). There were no significant differences in sonographic and functional improvement between the two intervention groups. Long-term prognostic issues; growth, functional impairment, and hypertension were not different between the two groups, but group 1 children experienced more recurrence of UTI than group 2 patients. CONCLUSION Conservative management is as effective as early surgical treatment in the management of infants with severe UPJO.

Abstract
BACKGROUND Though common, postoperative hydronephrosis (POHN) following ureteroneocystostomy raises concern for an underlying obstruction. We aimed to determine the clinical significance of POHN following open (OUR) or robotic (RALUR) ureteral reimplantation. METHODS We retrospectively reviewed pediatric patients who underwent ureteral reimplantation for vesicoureteral reflux (VUR) from 2008 to 2019 by a single surgeon. Baseline characteristics, operative outcomes, and trends in POHN were assessed. POHN was defined as new onset hydronephrosis or exacerbation of pre existing hydronephrosis. Renal ultrasounds were performed 1, 4, and 12 months postoperatively. Voiding cystourethrograms were performed 4 months postoperatively. Surgical experience for RALUR cases was defined as number of ureters operated over time. RESULTS Altogether, 93 patients (127 ureters) underwent RALUR and 19 patients (26 ureters) underwent OUR. POHN was found in 27.6% and 30.8% of ureters after RALUR and OUR, respectively. Rate and time to POHN resolution for RALUR (91.4%, 112 days) and OUR (75%, 211 days) were statistically similar. Odds of POHN after RALUR were directly related with preoperative VUR grade (Range OR: 2.82[2.26-3.52]) and surgical experience (Range OR: 8.88[7.16-11.02]). Surgical experience was inversely related with odds of VUR recurrence (Range OR: 0.41[0.32-0.54]). Rates of VUR resolution were comparable for OUR and RALUR patients. No patient required additional intervention for POHN. CONCLUSIONS Incidence and resolution rate of POHN after OUR and RALUR were similar. Higher VUR grades were associated with increased odds of POHN after RALUR. Increasing RALUR experience improved VUR resolution rate but increased odds of POHN. Surgical success rates were similar for RALUR and OUR. LEVEL OF EVIDENCE II.

A case report. WOMEN'S HEALTH (LONDON, ENGLAND) 2023; 19:17455057231181009.

Abstract
Pelvic actinomycosis with an intrauterine device accounts for approximately 3% of all actinomycoses. It is a chronic infectious disease characterized by infiltrative, suppurative, or granulomatous inflammation, sinus fistula formation, and extensive fibrosis, and caused by filamentous, gram-positive, anaerobic bacteria called Actinomyces israelii. The slow and silent progression favors pseudo tumor pelvic extension and exposes the patient to acute life-threatening complications, namely colonic occlusion with hydronephrosis. Preoperative diagnosis is often difficult due to the absence of specific symptomatology and pathognomonic radiological signs simulating pelvic cancer. We discuss the case of a 67-year-old woman who complained of pelvic pain, constipation, and weight loss for 4 months, and who presented to the emergency department with a picture of colonic obstruction and a biological inflammatory syndrome. The computed tomography scan revealed a suspicious heterogeneous pelvic mass infiltrating the uterus with an intrauterine device, the sigmoid with extensive upstream colonic distension, and right hydronephrosis. The patient underwent emergency surgery with segmental colonic resection and temporary colostomy, followed by antibiotic therapy. The favorable clinical and radiological evolution under prolonged antibiotic therapy with the almost total disappearance of the pelvic pseudo tumor infiltration confirms the diagnosis of pelvic actinomycosis and thus makes it possible to avoid an extensive and mutilating surgery with important morbidity.

Abstract
RATIONALE Ureteral triplication (UT) is a very rare disorder, with a challenging diagnosis and varied therapeutic methods. In the past, the treatment usually involved heminephrureterectomy of the stunted moiety. Here, we reported a case of complete UT that was treated by laparoscopic triple-ureteral ureteroureterostomy (UU). PATIENT CONCERNS A 2-year-old girl presented with frequent urine incontinence. Intravenous pyelography and voiding cystourethrography revealed a 3-segment left kidney with pelvi-ureteric dilation of the upper and middle moieties and grade IV to V vesicoureteral reflux. Laparoscopic triple-UU was successfully performed in the child, after which vesicoureteral reflux and urinary incontinence disappeared completely, hydronephrosis was improved, and hemirenal resection was avoided. DIAGNOSIS Based on the imageological examination results, the final diagnosis of the 2-year-old girl was as follows: left 3 renal pelvis with complete ureteral duplication, combined with upper and middle hydronephrosis, and upper and middle vesicoureteral reflux grade IV to V. INTERVENTION Laparoscopic triple-ureteral ureteroureterostomy was performed under general anesthesia. OUTCOMES The patient recovered smoothly without complications after surgery. At 6 months follow-up, ultrasonography of the urinary system showed that hydronephrosis of the dilated kidney segment was attenuated. LESSONS Laparoscopic triple-ureteral UU was successful in our patient. For children with duplex kidney and multiple ureteral duplications, minimally invasive urinary tract reconstruction can be a suitable intervention.

Abstract
Nephrolithiasis is a rare complication of renal transplantation. Patients with an obstructing calculus in a renal allograft often lack the usual renal colic symptoms, and therefore present with atypical symptoms. Treatment of obstructing calculi is imperative to prevent renal allograft failure and other complications. We report the case of a 46-year-old man who presented 28 years after renal transplant with renal failure and massive hydronephrosis secondary to an obstructing calculus.

Abstract
Ureteral stenosis is a comparatively rare complication following hematopoietic stem cell transplantation (HSCT). The etiology is still unclear and most believe that this may be due to the reactivation of BK virus in a state of immunodeficiency. In the later stages of ureteral stenosis with scarring, invasive interventions must be taken to relieve the hydronephrosis. Common treatments, such as D-J stent placement and permanent nephrostomy may not only entail the risk of infection, but also seriously affect the quality of life. Few cases of surgical intervention have been reported. In this article, a 25-year-old female was admitted to Peking University First Hospital suffering from recurrent flank pain. Seven years before, she developed hemorrhagic cystitis and bilateral urethritis 40 days after allogeneic HSCT. After continuous bladder irrigation and antiviral therapy, the left-sided hydronephrosis gradually alleviated while the right-sided one did not improve. D-J stents were used for urine drainage for 7 years before percuta-neous nephrostomy. Preoperative antegrade pyelography revealed significant hydronephrosis in the right kidney with long stricture of proximal-middle ureter. After comprehensive decision, she underwent ileal ureter replacement. The operation was successful. The segmental lesion was dissected and the scar tissue was removed. A 25 cm intestinal tube was isolated to connect the pelvis and bladder. An anti-reflux nipple was created at the distal end of ileal ureter to prevent the potential infection. The blood loss was minimal. After surgery, the drainage tube was removed in 2 weeks, the nephrostomy tube and the D-J stent was removed in 3 months. Follow-up mainly included clinical assessment, serologic testing, renal ultrasonography, blood gas analysis and radiological examination. During the follow-up of 6 years, she was symptom-free and no postoperative complications occurred. The serum creatinine level was stable. No hydronephrosis was observed under ultrasonography. Obvious peristaltic waves and ureteral jets of the ileal ureter was confirmed on cine magnetic resonance urography. To sum up, ureteral stenosis after HSCT is relatively rare. Obstruction caused by scarring is usually irreversible and surgical intervention should be designed according to the location and length of the lesion. Ileal ureter replacement can be a safe, feasible and effective method to solve this kind of complex stricture.

Abstract
A 7-week-old infant was presented at the emergency department with an abdominal mass, unilateral swelling of the groin and suspicion of an inferior caval vein syndrome with bluish discolouration and oedema of the lower extremities. Abdominal imaging showed two large cysts and profound bilateral hydronephrosis. Following laparotomy, an extreme hydrocolpos and an overdistended urinary bladder were found. These findings turned out to be secondary to a transverse vaginal septum. She was treated surgically and was hospitalised for 2 weeks. Long-term follow-up showed normalisation of previously present hypercalciuria and hydronephrosis.A hydro(metro)colpos should be considered in the differential diagnosis of a female infant presenting with an abdominal mass, to apply the appropriate investigations and therapy.

Abstract
OBJECTIVE To investigate the safety and efficacy of visualized ultra-mini percutaneous nephrolithotripsy (VUMP) and flexible ureterorenoscopy (FURS) in the treatment of nephrolithiasis patients with 1.5-2.5 cm kidney stones and without hydronephrosis. PATIENTS AND METHODS The clinical data of 143 nephrolithiasis patients without hydronephrosis (from April 2017 to March 2021) were collected and analyzed, including 65 cases in the VUMP group and 78 cases in the FURS group. The general clinical data, operation time, hospitalization time, recent stone-free rate (RSFR), long-term stone free rate (four weeks after operation, LSFR), Visual Analogue Scale (VAS), Bruggermann comfort score (BCS), and surgical complications of the two groups were collected and analyzed. RESULTS In the VUMP group, the operation time (49.14 ± 9.28 vs. 60.23 ± 9.45, p < 0.001), postoperative white blood cell count (11.05 ± 2.43 vs. 13.57 ± 2.71, p < 0.05) and BCS score (1.72 ± 0.80 vs. 2.81 ± 0.85, p < 0.001) were significantly lower than those of the FURS group, but the postoperative hemoglobin (8.25 ± 5.04 vs. 4.05 ± 3.07, p < 0.05), hospital stay (5.72 ± 1.75 vs. 3.12 ± 1.09, p < 0.001) and VAS score (3.18 ± 1.36 vs. 2.08 ± 1.28, p < 0.001) were significantly higher than those of the FURS group. Besides, the VUMP group was significantly higher than the FURS group in RSFR (90.32% vs. 72.22%, p < 0.05) and LSFR (95.38% vs. 85.89%, p < 0.05). The systemic inflammatory response syndrome rate (3.07% vs. 14.10%, p = 0.037) and total complications (9.23% vs. 20.51%, p = 0.032) were significantly lower in the VUMP group than in the FURS group. CONCLUSIONS Both VUMP and FURS are safe and effective in the treatment of nephrolithiasis patients with 1.5-2.5 cm kidney stones and without hydronephrosis, and the former is preferable for higher SFR, shorter operation time and lower complication rate.

Abstract
Presentation A 27-year-old male presented to the Emergency Department with acute severe left flank pain following ingestion of 5 pints of beer. Approximately 20 bouts of similar episodes over the past year, in the setting of alcohol ingestion. Despite attending GP, no diagnosis reached yet. Diagnosis "Pelvo-ureteric junction (PUJ) obstruction Syndrome". Bedside ultrasound in the Emergency Department during the acute pain crisis: massive hydronephrosis left kidney. Finding confirmed on CT scan. Subsequent 99m-Tec renogram showed markedly decreased renal function on the left. Treatment Interval Pyeloplasty two months later. Conclusion Delayed recognition is the norm for PUJ obstruction syndrome, as CT/MRI/US studies often do not display hydronephrosis if the patient is asymptomatic. We could not find any reports in the literature of diagnosing PUJ obstruction syndrome using bedside ultrasound in the Emergency Department. We advise acquiring rapid bedside ultrasound imaging in suspected cases of PUJ obstruction syndrome, enabling earlier diagnosis.

Abstract
Purpose To investigate the puncture accuracy and feasibility of contrast-enhanced ultrasound (CEUS) guided percutaneous nephrolithotomy (PCNL) in flank position for patients with no apparent hydronephrosis. Methods Between May 2018 and June 2020, 72 kidney stone patients with no or mild hydronephrosis were randomized into two groups: a CEUS-guided PCNL group and a conventional ultrasound (US)-guided group. Patients’ demographics and perioperative outcomes were compared, including the success rate of puncture via calyceal fornix, the success rate of a single-needle puncture, puncture time, operative time, postoperative hemoglobin loss, stone-free rate, incidence of complications and postoperative stay. Results The success rate of puncture via calyceal fornix for CEUS-guided group was significantly higher than that for conventional US-guided group (86.1 vs. 47.2%, p = 0.002). Patients performed with CEUS-guided PCNL required shorter renal puncture time than those guided with conventional US (36.5 s vs. 61.0 s, p < 0.001). The median postoperative hemoglobin loss in the CEUS-guided group was significantly lower than that in conventional US-guided group (2.5 vs. 14.5 g/L, p < 0.01). There was no statistically significant difference in the success rate of a single-needle puncture, operative time, stone-free rate, incidence of complications and postoperative stay between the two groups. Conclusion CEUS guidance facilitates identification of the renal calyx fornix, and benefits more precise renal puncture and less hemoglobin loss in PCNL. CEUS-guided PCNL in flank position is a feasible approach to the treatment of kidney stone patients with no apparent hydronephrosis.

Abstract
Acquired hydronephrosis following cystectomy and ileal conduit urinary diversion for bladder cancer is most commonly caused by stricture of the ureter or the ureteroenteric anastomosis. Nevertheless, malignant obstruction due to ureteral tumor recurrence must be ruled out. Neuroendocrine tumors of the ureter are extremely rare and an unlikely cause of hydronephrosis in this setting. We present the first reported case of a patient with a history of bladder cancer and an ileal conduit presenting with hydronephrosis secondary to an obstructing carcinoid tumor of the ureter.

Abstract
A 47-year-old woman with a complaint of weight loss for the past 5 months was referred to our hospital. Colonoscopy revealed advanced rectal cancer 20 cm from the anal verge. The patient had left hydronephrosis caused by ureteral invasion. Firstly, we performed transverse colostomy and left nephrostomy. After 8 courses of capecitabine, oxaliplatin plus bevacizumab( CAPOX plus Bmab)therapy, colonoscopy and computed tomography revealed shrinkage of both the primary and metastatic lesions. Laparoscopic high anterior resection was performed, and the left ureter was successfully preserved. The patient received chemotherapy after surgery. Neither local recurrence nor enlargement of metastases has been observed 8 months after surgery.

[PMID: 34521599 DOI: 10.1016/j.jpurol.2021.08.013] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/02/2021] [Revised: 06/24/2021] [Accepted: 08/12/2021] [Indexed: 11/19/2022]
Abstract
INTRODUCTION AND OBJECTIVE The value of diuretic renography drainage times in congenital hydronephrosis (AHN) decision making is controversial. Recently, a group suggested a modification to the classically described diuretic drainage time cut-off values. They found that a drainage half-time (T1/2) < 5 min was normal whereas a T1/2 exceeding 75 min predicted pyeloplasty. In addition, they reported on the benefit of a delayed drainage image obtained with gravity assistance. We sought to evaluate the ability of these modified T1/2 criteria to predict pyeloplasty, alone or in combination with a delayed drainage image referred to as Global Washout (GWO). METHODS We retrospectively reviewed 113 patients, including consecutive pyeloplasties for AHN from 2004 to 2018. Patients who underwent pyeloplasty due to low differential renal function (DRF) < 30% or infection were excluded. The control group comprised high grade AHN managed non-operatively. The initial renal ultrasound and MAG 3 Lasix renogram were reviewed for grade, differential renal function (DRF), T1/2 and GWO. A ROC curve was used to evaluate the T1/2 and GWO cut-off points that can predict pyeloplasty, using a p-value of less than 0.05. RESULTS The pyeloplasty group consisted of 62 patients and the control group consisted of 51 patients. Two patients (3%) in the pyeloplasty group had a T1/2 < 5 min whereas 21 (34%) had T 1/2 > 75 min (p < 0.001). In the control group, 25 patients (49%) had T 1/2 < 5 min and none had T1/2 >75 min (P < 0.001). The ROC curve for T1/2 < 5 min demonstrated 94% sensitivity and 51% specificity whereas a T1/2 >75 min demonstrated 100% specificity and 34% sensitivity. Analysis of the GWO using a ROC curve revealed that a cut-off of 50% GWO has 100% specificity and 52% sensitivity for pyeloplasty. Overall, a T1/2 > 75 min or GWO <50% predicted 53% of pyeloplasties (Fig A) and was absent in all conservatively managed cases. DISCUSSION The limitations of the present study include its retrospective nature. Secondly, the lack of a gold standard diagnostic test for uretero-pelvic junction obstruction hampers objective quantification of diagnostic test utility performance. CONCLUSIONS We confirm the utility of the modified diuretic half-time criteria and delayed gravity assisted imaging. A T1/2 > 75 min or GWO <50% are indicators of severity whereas a T1/2 of <5 min or GWO >90% is reassuring. Gravity assisted delayed imaging can be especially helpful in cases with indeterminate T 1/2 times and should be included in the standard assessment of hydronephrotic kidneys. These parameters can be used to tailor the frequency and invasiveness of imaging within observation protocols.

Abstract
Xanthogranulomatous pyelonephritis (XGPN) is an uncommon chronic destructive granulomatous inflammation of the kidney with variable clinical and radiological presentation. Due to its similarities to other benign and malignant pathologies, a high index of suspicion is required for preoperative diagnosis, which will ensure appropriate management of this condition. The invasion into the surrounding structures such as pararenal spaces, psoas muscle, small bowel, diaphragm, lung or soft tissues has been reported. However, involvement of ureter is very rarely reported. We report a rare case of left-sided gross hydronephrosis with staghorn calculus with giant uretic calculi, postnephrectomy on the biopsy diagnosis of XGPN was made, which also revealed involvement of ureter also.

Abstract
INTRODUCTION Late diagnosis of renal tuberculosis leads to complications that cannot be eliminated by treatment. CLINICAL CASE A clinical observation of patient Ch., born in 1976, who was admitted to TB Research Institute of Ministry of Health of Russia on 17.02.2020. A diagnosis was cavernous renal tuberculosis. Tuberculosis of the ureter. MBT (-). Right ureteral stricture (obliteration), complicated by ipsilateral hydronephrosis. Right nephrostomy tube (2018). Clinical cure of disseminated pulmonary tuberculosis. He underwent planned laparoscopic bowel substitution of the right ureter on 10.03.2020. In the postoperative period, pyelonephritis developed, which was resolved by drug therapy. CONCLUSION In this case, there is the correct tactics of outpatient urologists. When hydronephrosis was diagnosed, a nephrostomy tube was put, which allowed to preserve the kidney, Then the patient was immediately referred to a phthisiatrician to exclude urogenital tuberculosis. In the local TB dispensary, the patient did not have the opportunity to receive necessary treatment, and he was transferred to the TB Research Institute of Ministry of Health of Russia, where a reconstructive laparoscopic procedure was performed.

Abstract
Pelvic lipomatosis is a rare benign entity characterised by excessive deposition of adipose tissue in the perirectal and perivesical spaces. We describe a 43-year-old man with bilateral distal ureteral obstruction secondary to pelvic lipomatosis with concomitant proliferative cystitis resulting in severe hydronephrosis. We performed urinary diversion with percutaneous nephrostomy tube insertion to prevent further renal impairment. The patient was advised close follow-up to monitor the increased risk of bladder adenocarcinoma transformation observed in patients with cystitis glandularis. This report, compliant with the CARE (CAse REport) guidelines for clinical case reporting, presents another case of pelvic lipomatosis associated with acute kidney failure, bilateral hydronephrosis and proliferative cystitis without urodynamic evidence of bladder outlet obstruction that may serve to guide urologists in managing patients with a similar profile.

Abstract
RATIONALE Ureteral obstruction of the graft kidney is a common complication of kidney transplantation. However, ureteral obstruction caused by inguinal hernia has rarely been reported. We present a rare case of ureteral obstruction with allograft dysfunction caused by an inguinal hernia. PATIENT CONCERNS A 76-year-old man, who was a renal transplant recipient, presented with bilateral pitting oedema, reduced urine output, and right inguinal hernia. DIAGNOSES Abdominal computed tomography revealed severe hydroureteronephrosis of the kidney allograft. A right inguinal hernia with ureteral incarceration was observed. INTERVENTIONS The patient underwent graft percutaneous nephrostomy, followed by antegrade insertion of a double-J tube (DJ). Gradual improvement was observed in his renal function. Right inguinal herniorrhaphy was performed 5 days later. OUTCOMES The renal function returned to normal after percutaneous nephrostomy and insertion of the DJ. A right inguinal direct-type hernia with ureter adhesion to the hernial sac was observed during the surgery. The posterior wall defect was repaired by the McVay technique. The DJ was removed after 1 month. The patient's renal function remained stable at 6-month follow-up. LESSONS The orientation of the graft kidney has a significant influence on the location of the ureter. Upward orientation of the hilum will result in superficial location of the ureter, rendering it close to the hernial sac and susceptible to incarceration. The transplant surgeon should be aware of such a presentation of graft dysfunction with inguinal hernia to prevent a delay in the diagnosis and graft loss.

Abstract
INTRODUCTION This work reports a patient with recurrent renal calculi subjected to three surgeries in half a year to be in the same position, and the high-throughput sequencing data showed different species in the renal pus and urine samples, which suggested that partial renal infection or stone formation can be judged by the bacteria in urine. PATIENT CONCERNS The female patient aged 43 years was referred to the authors' department on April 13, 2020, due to left waist pain and fever for 3 days. DIAGNOSIS Kidney stones and hydronephrosis were determined by a urinary system computed tomography scan. INTERVENTIONS On April 20, 2020 and June 15, 2020, the patient was successfully treated with left percutaneous nephrolithotomy twice under general anesthesia. An investigation on the health and eating habits of the patient within 6 months was completed at the last admission. The components of the second renal calculus sample were analyzed with an infrared spectrum analyzer. The third renal stone (renal pus, triplicates) was subjected to microbial metagenome sequencing, and urine samples before and after surgery were subjected to 16S RNA sequencing by SEQHEALTH (Wuhan, China). OUTCOMES After percutaneous nephrolithotomy, the left kidney stones were basically cleared, stone analysis revealed that the main components were calcium oxalate monohydrate, silica, and a small amount of calcium oxalate dehydrate. Although the urine samples exhibited differences, the renal pus and urine sample shared a single species. CONCLUSION It is not clear that the prospects of partial renal infection or stone formation can be judged by the bacteria in urine.

Abstract
CASE DESCRIPTION An 8-month-old 41.2-kg (90.6-lb) sexually intact male Dogue de Bordeaux with urinary incontinence and signs of nausea was referred for further evaluation and treatment of bilateral hydronephrosis, hydroureter, and ectopic ureters. CLINICAL FINDINGS Clinicopathologic analyses revealed urine specific gravity and serum concentrations of urea nitrogen and creatinine within reference limits. Abdominal ultrasonography and CT revealed unilateral abdominal cryptorchidism, ureters that bilaterally passed dorsal to and appeared compressed by the external iliac arteries (retroiliac ureters), and bilateral hydronephrosis, hydroureter, and ectopic ureters. On CT, minimal uptake of contrast medium by the right kidney indicated either a lack of renal function or ureteral obstruction. TREATMENT AND OUTCOME The dog underwent exploratory laparotomy, right ureteronephrectomy, left neoureterocystostomy, bilateral castration, and incisional gastropexy without complication and was discharged 2 days postoperatively. Eleven days after surgery, the dog had improved but continued urinary incontinence, improved left hydronephrosis and hydroureter, and serum concentrations of urea nitrogen and creatinine within reference limits. At 24 months after surgery, the dog was reportedly clinically normal, other than having persistent urinary incontinence. CLINICAL RELEVANCE To our knowledge, this was the first report of a dog with retroiliac ureters and compression-induced ureteral obstruction with secondary hydroureter and hydronephrosis. Retroiliac ureters should be considered as a differential diagnosis in young dogs with ureteral obstruction. Our findings indicated that a good outcome was possible for a dog with retroiliac ureters treated surgically; however, the presence of additional congenital anomalies should be considered and may alter the prognosis in dogs with retroiliac ureters.

Abstract
Introduction and Objective: Forniceal rupture due to obstructing ureterolithiasis (FROU) is a seldom encountered radiographic finding, but the impact of this diagnosis and influence on stone management has not been well studied in the literature. The purpose of the study is to examine stone characteristics and intervention patterns of patients with radiographic evidence of FROU. Materials and Methods: A retrospective analysis of all patients with radiographic evidence of FROU was compared with patients with obstructing ureteral stones without forniceal ruptures (noFROU). All patients presented to our Emergency Department from January 2015 until December 2018. Data analyzed included patient demographics, clinical presentation, stone characteristics, and management pattern. Primary outcome was need for hospital admission and surgical intervention. Results: Thirty-two patients with FROU (mean age = 45) were compared with 50 patients with noFROU (mean age = 57). Univariate analysis revealed that age, history of diabetes mellitus, history of hypertension, days of symptoms, degree of hydronephrosis, and degree of perinephric stranding were associated with forniceal rupture (p ≤ 0.05). On multivariate analysis, only degree of perinephric stranding remained significant (p ≤ 0.05). Average maximum axial stone diameter in the FROU group was 5.1 mm vs 4.7 mm in the noFROU group (p = 0.66). Overall, 68.8% of stones were located within the distal ureter in the FROU group vs 48.8% in the noFROU group (p = 0.09). There was no difference in hospital admission (FROU 37.5% vs noFROU 44%, p = 0.56) and need for surgical intervention (FROU 50% vs noFROU 48%, p = 0.86). There were no 30-day complications in patients with FROU. Conclusions: Ureteral stone location and size does not seem to impact the presence of FROU. FROU may be an alarming reported finding but its presence does not appear to impact clinical outcomes or affect urological management, including admission or need for urologic intervention.
