Abstract
Purpose We undertook a prospective planning study to describe the delineation of ileal conduit (IC) loop on radiotherapy planning computed tomography (RTP CT) scan as an organ at risk (OAR) and its sparing using volumetric modulated arc therapy (VMAT) during adjuvant irradiation of bladder malignancies. Materials and Methods Fifteen patients with bladder malignancy needing adjuvant radiotherapy postoperatively and having normal renal function underwent delayed phase RTP CT from June 2020 to March 2021, with certain modifications (Foley's catheter through stoma, additional delayed scans). We identified the course of ureters, external stoma, IC, and uretero-ileal (right and left) anastomotic sites. VMAT plans were generated. Results A step-by-step description is given. Genitourinary OARs include kidneys, ureters, uretero-ileal anastomoses, and IC. The contrast on delayed scan opacifies ureters and IC. IC can be seen three-dimensionally as a structure with two fixed ends (blind proximal end anterior to the right sacroiliac joint and the open distal end over the right anterior abdominal wall in parasagittal location) and a 15-20 cm hanging intraabdominal loop that lies adjacent to the right iliac vessels. For prescription doses (PD) of 50.4 gray and 54 gray, respectively, VMAT plan achieved IC dose maximum to less than PD and V50 lower than 10 cc. Stoma sparing traditionally used as a surrogate for IC sparing is insufficient due to the variable intraabdominal location of IC loop. Conclusions Delineation of IC as an OAR is feasible with slight modifications in the RTP protocols. VMAT (or other forms of intensity modulated radiation therapy) can help IC sparing and should be considered when it lies in close proximity to target volumes and the risk of additional morbidity is considerable.

Abstract
INTRODUCTION In patients with a history of radical cystectomy and with intestinal diversion, urolithiasis in the upper urinary tract is a frequent event. MATERIAL AND METHODS We describe for the first time a case of retrograde endoureterotomy used to treat a calculus proximal to the ureterointestinal junction. RESULTS This technique is of interest when antegrade access is not possible. In our example, after passing the guidewire percutaneously, and externalize it through the stoma, the left meatus was reached with a resectoscope inserted through the ileal duct. After the use of a balloon to prevent migration of the calculus, a retrograde endoureterotomy was performed with a Collins knife and the stone removed. The patient's progress was satisfactory. CONCLUSION Endoscopic management of calculi in patients with intestinal diversion can be performed with different approaches. We recommend retrograde endoureterotomy as a feasible treatment option for the removal of impacted calculi at the ureterointestinal junction.

Abstract
There are needs to evaluate the risk factors for urinary infection after retrograde upper urinary lithotripsy, to provide insights into the management and nursing care of patients with retrograde upper urinary lithotripsy.Patients who received retrograde upper urinary lithotripsy with a Foley 20 urinary tube insertion from June 1, 2019 to December 31, 2020 in our hospital were selected. Patients were grouped urinary infection and no infection group according to the culture results of urine, and the clinical data of the 2 groups of patients were collected and compared. Single factor and logistic regression analysis were used to analyze the risk factors of urinary tract infection after retrograde upper urinary lithotripsy.Four hundred ten patients with retrograde upper urinary lithotripsy were included, of whom 62 patients had the urinary tract infection, the incidence of urinary tract infection was 15.12%. There were significant differences in the gender, age, diabetes, stone diameter, duration of urinary tube insertion and duration of surgery between infection and no-infection group (all P < .05). The Escherichia coli (62.90%) was the most commonly seen bacterial in patients with urinary tract infection. Female (odds ratio [OR]: 1.602, 95% confidence interval 95% [CI]: 1.132∼2.472), age >50 years (OR: 2.247, 95% CI: 1.346∼3.244), diabetes (OR: 2.228, 95% CI: 1.033∼3.451), stone diameter ≥2 cm (OR: 2.152, 95% CI: 1.395∼3.099), duration of urinary tube insertion ≥3 days (OR: 1.942, 95% CI:1.158∼2.632), duration of surgery ≥90 minutes (OR: 2.128, 95% CI: 1.104∼3.846) were the independent risk factors for the postoperative urinary tract infection in patients with retrograde upper urinary lithotripsy (all P < .05).The incidence of urinary tract infection in patients undergoing retrograde upper urinary lithotripsy was high, counteractive measures targeted on those risk factors are needed to prevent and reduce the postoperative urinary infection in clinical settings.

Abstract
Acute obstructive uropathy is a medical emergency, which often is accompanied by acute renal failure or sepsis. Treatment options to resolve the acute obstructive process include conservative medical management, retrograde ureteral stenting, or placement of percutaneous nephrostomy or nephroureteral catheters. It is important to understand the various treatment options in differing clinical scenarios in order to guide appropriate consultation. Prompt attention to the underlying obstructive process is often imperative to avoid further deterioration of the patient's clinical status. A summary of the data and most up-to-date clinical trials regarding treatment options for urinary tract obstruction is outlined in this publication. The American College of Radiology Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision include an extensive analysis of current medical literature from peer reviewed journals and the application of well-established methodologies (RAND/UCLA Appropriateness Method and Grading of Recommendations Assessment, Development, and Evaluation or GRADE) to rate the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances where evidence is lacking or equivocal, expert opinion may supplement the available evidence to recommend imaging or treatment.

Abstract
Objective To present our experience in minimally invasive management of urinary tract stones in patients with urinary diversion. Materials and Methods We retrospectively reviewed 26 patients with urinary tract stones after cystectomy and urinary diversion. The types of urinary diversion were ileal conduit, colon conduit, ileal orthotopic neobladder in 19, 4, and 3 patients, respectively. At postoperative days 2, a plain KUB and urinary ultrasonography were performed in order to assess stone fragmentation or hydronephrosis. According to postoperative imaging, stone free rate (SFR) was defined as complete absence of fragments or residual stones less than 4mm. Results 19 patients were treated with minimally invasive percutaneous lithotripsy (MPCNL) and 2 patients required second-look MPCNL. Anterograde flexible ureteroscopy was performed in 2 patients, while in 2 patients a combined anterograde and retrograde approach was required. Three reservoir stones were treated by transurethral neo-bladder lithotripsy. Postoperative significant complications occurred in 2 patients (7.7%). The highest percentage of stone composition was struvite, as a result of chronic urinary tract infection (UTI). SFR was 88.5% (23 of 26). Conclusions Our experience showed that MPCNL is a safe and effective treatment modality with little morbidity for renal and upper ureteral stones in patients with urinary diversion. For middle and lower ureteral stones, an anterograde approach could be also considered as a first line treatment, but a combined anterograde and retrograde approach was required when the anterograde access alone cannot provide acceptable results.

Abstract
The advantage of a retrograde over an antegrade approach in ileal conduit diversion is the lower morbidity. Furthermore, in cases in which there are bone deformities and no ureteral reflux from the reservoir into the upper tract, percutaneous access can be challenging. Thus, a retrograde approach should be considered as the first-line option for the treatment of renal stones in patients with an ileal conduit, but the urologist should keep in mind that an antegrade or combined approach may be possible in the case of failure.

Abstract
INTRODUCTION Patients with ileal conduit urinary diversions are at an increased risk of long-term upper urinary tract (UUT) complications, including anastomotic strictures, infections, and urolithiasis. The reconstructed urinary system poses challenges for endoscopic manipulation. We present and describe our dual-center experience in performing retrograde ureteroscopy to treat or diagnose UUT abnormalities in patients with ileal conduit incontinent diversion. PATIENT AND METHODS We performed a retrospective analysis of medical records for all patients with previous urinary diversion who underwent retrograde ureteroscopic procedures via the ileal loop in our institutions over a 9 year period (between June 2007 and August 2016). RESULTS Fifty-four procedures were performed in 36 patients. Mean age was 61 (28-90) years. Average time from diversion to ureteroscopic procedure was 13.0 (0.08-53) years. Stone disease was the most common indication for intervention in 35.2% (19/54) of cases, with a stone-free rate of 78.9% (15/19). Other indications included surveillance of transitional-cell carcinoma in 22.2% (12/54), diagnostic flexible ureteroscopy (fURS) in 20.4% (11/54), stricture management in 11.1% (6/54), removal of encrusted stent/nephrostomy in 7.4% (4/54), urine leak after diversion in 1.9% (1/54), and miscellaneous in 1.9% (1/54). Successful retrograde access was possible in 74% (40/54) of cases. A long and tortuous ileal segment, too difficult to negotiate, was the most common cause of failure to access the UUT. In 13 out of 54 (24.1%) cases, retrograde fURS was combined with simultaneous percutaneous antegrade access. Six patients (11.1%) developed postprocedural pyrexia requiring additional antibiotic therapy, and one (1.9%) patient required embolization of the renal artery for ongoing bleeding. Median length of stay was 1 day (0-55), with 13 (24%) being performed as day-case procedures. CONCLUSIONS Retrograde ureteroscopy in patients with ileal conduits can be technically challenging due to distorted anatomy. This procedure can be safely performed in experienced hands with standard endourological equipment. An antegrade approach can be carried out simultaneously, which may be required in a small number of patients.

Abstract
PURPOSE Ureteroenteric strictures represent the most common complication requiring reoperation after radical cystectomy. We investigated the prevalence, outcomes, predictors and management of ureteroenteric strictures. MATERIALS AND METHODS We retrospectively reviewed our quality assurance, robot assisted radical cystectomy database to identify patients in whom ureteroenteric strictures developed. Data were reviewed for demographics, perioperative outcomes and ureteroenteric stricture characteristics. The Kaplan-Meier method was used to calculate time to ureteroenteric stricture and multivariable stepwise regression was done to evaluate predictors of ureteroenteric strictures. RESULTS Ureteroenteric strictures developed in 12%, 16% and 19% of 51 patients (13%) at 1, 3 and 5 years after robot assisted radical cystectomy, respectively. All patients were initially treated endoscopically or percutaneously, including 57% treated only endoscopically or percutaneously and 43% who required surgery, which was open repair in 6 and robot assisted repair in 16. At a median followup of 23 months 33 patients (65%) were free of disease, including 13 after endoscopic or percutaneous treatment, 15 after robot assisted repair and 5 after open revision. Open and robot assisted revisions showed comparable perioperative outcomes. On multivariable analysis the predictors of ureteroenteric anastomotic strictures were body mass index (OR 1.07, 95% CI 1.01-1.13, p = 0.02), intracorporeal urinary diversion (OR 3.28, 95% CI 1.41-7.61, p = 0.006), length of the right resected ureter (OR 0.66, 95% CI 0.50-0.88, p = 0.004), estimated glomerular filtration rate 30 days after assisted radical cystectomy (OR 0.85, 95% CI 0.74-0.98, p = 0.03), urinary tract infection (OR 2.68, 95% CI 1.31-5.49, p = 0.007) and leakage (OR 3.85, 95% CI 1.05-14.1, p = 0.04). Male gender (OR 0.19, 95% CI 0.04-0.96, p = 0.04) and higher body mass index (OR 0.85, 95% CI 0.72-0.996, p = 0.05) were associated with lower odds of successful endoscopic management. CONCLUSIONS Multiple modifiable factors were associated with ureteroenteric anastomotic strictures following robot assisted radical cystectomy. Surgical revision can provide a definitive management with comparable outcomes for open and robotic repairs.

Abstract
OBJECTIVE To assess the outcomes of patients following a first-line systematic endourologic procedure used to treat ureteroenteric anastomotic strictures (UEAS). MATERIALS AND METHODS All data from patients treated using a first-line endourologic approach for UEAS between 2010 and 2015 were reviewed retrospectively. The following data were analyzed: age, type of urinary diversion, initial symptoms, surgical endoscopic approach (antegrade or retrograde), pre- and postoperative creatinine levels, and postoperative complications and outcomes. Follow-up visits occurred at 6 weeks, 3 months, and 6 months postoperatively, and at least annually thereafter. RESULTS A total of 27 patients (median age: 62.5 years) were included. Overall, 28 UEAS were treated endoscopically (ileal conduit: n = 25; neobladder: n = 3). Most UEAS developed following radical cystectomy for bladder cancer (n = 19). Overall, the endoscopic approach was successful in 20 cases (71.4%). The UEAS length was >1 cm in 21 cases (75%). All UEAS of <1 cm were treated successfully (n = 7). There were three grade II and five grade III complications. The median follow-up period was 25 months. The median creatinine levels before surgery and at last follow-up were 1.3 mg/dL and 0.9 mg/dL, respectively. CONCLUSION An endourologic procedure is a reasonable option for first-line treatment for UEAS and has promising functional outcomes and limited morbidity.

Abstract
The focus of this guideline is the management of ureteral stones. Specifically, the topics covered include: conservative management, medical expulsive therapy, active intervention with either shockwave lithotripsy (SWL) or ureteroscopy (URS), factors affecting SWL treatment success, optimizing success, and special considerations (e.g., pregnancy, urinary diversion). By performing extensive literature reviews for each topic evaluated, we have generated an evidence-based consensus on the management of ureteral stones. The objective of this guideline is to help standardize the treatment of ureteral stones to optimize treatment outcomes.

Abstract
PURPOSE There is a paucity of data regarding the operative management of complications after robot-assisted radical cystectomy. We reviewed operative management of robot-assisted radical cystectomy specific complications during our 10-year experience with this procedure and assessed the feasibility, safety and outcomes of robot-assisted reoperations. MATERIALS AND METHODS We retrospectively reviewed the records of all patients who underwent surgical interventions for robot-assisted radical cystectomy specific complications between 2005 and 2015. Univariable and multivariable logistic regression models were fit to evaluate predictors of surgical intervention after robot-assisted radical cystectomy. Kaplan-Meier curves were used to describe time to surgical interventions. RESULTS A total of 92 patients (23%) underwent surgical intervention after robot-assisted radical cystectomy. Mean followup was 27 months. Average time to any surgical intervention after cystectomy was 14 months. The reoperation rate was 5%, 2% and 16% at 30, 31 to 90 and greater than 90 days, respectively. Using the Kaplan-Meier method surgical interventions occurred at a rate of 30% at 2 years and 46% at 5 years. Interventions for ureteroileal complications were the most common (48 cases) followed by interventions for bowel obstruction, fistulas and abdominal wall related complications (11 cases). Clavien 3 or greater complications and neoadjuvant chemotherapy were associated with surgical intervention. CONCLUSIONS Even in experienced hands the long-term complications of robot-assisted radical cystectomy are notable. Of our patients 23% required surgical interventions after the procedure. Our initial experience with robot-assisted management of robot-assisted radical cystectomy complications appears safe and feasible, although the decision to proceed is determined primarily by surgeon experience.

Abstract
A ureteral stricture is a rather rare urological event defined as a narrowing of the ureter causing a functional obstruction and renal failure, if left untreated. The aim of this review article is to summarize and discuss current knowledge on the incidence, pathogenesis, management, and follow up of proximal, mid, and distal ureteral strictures.

Abstract
PURPOSE We assessed our experience performing retrograde ureteroscopy (URS) in patients with a continent urinary diversion. METHODS A retrospective review was performed of patients with a continent urinary diversion necessitating URS for diagnostic or therapeutic purposes from 2002 to 2013. RESULTS We identified 11 male and 1 female patients with a continent urinary diversion with a mean age of 62.5 years (27-77) who underwent 13 procedures on 17 renal units. Indication for URS was diagnostic in 10 (77%), stone disease in 2 (15%), and stricture in 1 (8%). URS was attempted a median of 6.2 years (1.3-14.5) after diversion creation. Retrograde URS was attempted in 17 renal units with 10 (59%) accessed successfully. One procedure was staged with antegrade wire access obtained before retrograde URS. Inability to identify the afferent limb or ureteral orifice one (20%), tortuosity of afferent limb two (40%), angulation one (20%), and length of the afferent limb one (20%) were causes for unsuccessful retrograde URS. Of the successfully attempted retrograde URS, 75% occurred within the past 5 years. There were no complications in the successful retrograde URS group. Ureteral stents or nephrostomy tubes were left in place postprocedure in six (50%) patients. CONCLUSION While technically challenging, retrograde URS can be performed successfully in patients with an orthotopic neobladder once the learning curve for the procedure is overcome.

Abstract
PURPOSE To determine the yield of CT urography (CTU) in the surveillance of patients with bladder cancer following cystectomy. MATERIALS AND METHODS In this IRB-approved, HIPAA-compliant, retrospective study of 5,404 CT urograms performed at our institution between March 2000 and February 2011, 225 CT urograms were performed in 105 patients [79 men, 26 women; mean age 65 years (43-85)] following cystectomy for bladder cancer. Median follow-up after cystectomy was 63 months (range 1-234), median time between cystectomy and CTU was 39 months (range 0-229), median follow-up after CTU was 34 months (range 1-111). CTU examinations were reviewed by two radiologists in consensus and findings were categorized into those related to surgery, locoregional recurrence, metastases, or metachronous upper tract urothelial tumor (UTT). FINDINGS Findings were present in 69 (65.7 %) of 105 patients, including findings related to surgery in 60 (57.1 %) patients, locoregional recurrence or metastatic disease in 21 (20 %) patients, and UTT in 3 (2.9 %) patients. Of surgery-related findings, hydronephrosis (23/105, 21.9 %) and parastomal hernia (17/105, 16.2 %) were the most common findings. Visceral metastases (16/105, 15.2 %) and lymph node metastases (13/105, 12.4 %) were the most common manifestations of recurrent disease. CONCLUSION CTU findings in the surveillance of patients with bladder cancer after cystectomy are common and include those related to surgery, spread of the disease, and metachronous tumors. Our study supports current published guidelines on the use of CTU in these patients.

Abstract
We report the case of a 24-year old man with a past history of vesical extrophy and ureterosigmoidostomy in childhood, admitted with acute left flank pain and acute renal failure. The complaints started the day following the endoscopic resection of a sigmoid polyp. The stricture of the ureterosigmoid junction was diagnosed by intravenous urography. Conservative treatment with endo-ureteral dilatation was successfully performed. At 2 years of follow-up, the patient is still asymptomatic, without any residual hydronephrosis.

Abstract
Stones in abnormal situations present a management conundrum to the urologist. Many of these situations are relatively rare and literature is scanty on the appropriate management. We review the current literature on the management of stones in the setting of pregnancy, calyceal diverticulum, urinary diversions, pelvic kidneys, transplant kidneys, autosomal dominant polycystic kidney disease, horseshoe kidneys, and other renal anomalies. The aims of treatment are complete stone-free status. The modality of treatment should be individualized to the size and location of stone and type of abnormal situation confronted.

Abstract
Patients undergoing urinary diversion are at high risk for developing stone disease due to the metabolic and structural features intrinsic to the creation of a urinary reservoir. The utilization of shockwave lithotripsy as well as antegrade and retrograde endoscopic techniques in appropriately selected patients affords a relatively safe and effective means of stone removal. This review focuses on the etiology of stone formation in patients with urinary diversion and examines the most relevant and current reports on expulsive techniques and their associated outcomes for patients within this population who develop upper urinary tract calculi.
