Abstract
BACKGROUND Both mini-percutaneous nephrolithotomy (mPNL) and retrograde intrarenal surgery (RIRS) are two major strategies for the endourological management of kidney stones. In the current study, we aimed to compare the efficacy and safety of mPNL and RIRS for the treatment of 10-20 mm kidney stones in patients with ileal conduit. METHODS Patients with a history of bladder cancer and ileal conduit who had undergone mPNL or RIRS for unilateral kidney stones 10-20 mm in size between January 2015 and June 2022 were retrospectively included. Baseline characteristics and perioperative outcomes were analyzed and compared between mPNL and RIRS. RESULTS The failure rate of the initial surgery was 2.5% and 18.9% for mPNL and RIRS, respectively (P=0.025). In total, 39 and 30 patients were finally included in the mPNL and RIRS groups. One-session stone-free rate (SFR) was higher in the mPNL group than the RIRS group (97.4% vs. 66.7%, P=0.002). However, there was no statistically significant difference between the two groups with regard to operation time, postoperative hospitalization, complications according to Clavien-Dindo classification, as well as the change in hemoglobin, creatinine, procalcitonin, and pain Visual Analogue Scale Score before and after the surgery. Moreover, Results were consistent across subgroup analyses in patients stratified by years (2015-2018 and 2019-2022). CONCLUSIONS Both mPNL and RIRS were feasible and safe for the treatment of 10-20 mm kidney stones in patients with ileal conduit. However, mPNL achieved superior SFR outcomes with a similar incidence of complications, and it might be a sensible alternative for selected patients.

Abstract
OBJECTIVE To investigate the safety, efficacy, and surgical approach of percutaneous bladder calculi removal in adult patients with prior lower urinary tract reconstruction utilizing bowel using a single-institution database. METHODS Twenty patients with prior history of lower urinary tract reconstruction (continent cutaneous urinary reservoir, augmentation enterocystoplasty with catheterizable channel, or ileal neobladder) who underwent percutaneous cystolitholapaxy from 2014 to 2020 were identified from an IRB-approved database. Analysis of patient demographics, operative details, stone composition, stone-free rates, recurrence, and associated complications was performed. RESULTS Percutaneous access and either ultrasonic lithotripter or laser lithotripsy were utilized to remove bladder stones. Over half of the patients also underwent concomitant renal stone removal via percutaneous removal or retrograde ureteroscopy. Postoperative computed tomography imaging revealed complete bladder stone clearance in 90% of patients. There were no notable complications from percutaneous bladder stone removal and most patients were discharged either the same day or within 24hours. Urine and stone analysis revealed infection was present in the majority of patients. Bladder stones recurred in 45% of patients after more than 2years of follow-up, on average. CONCLUSION Percutaneous cystolitholapaxy is a safe and effective approach for the removal of moderate-sized bladder calculi in adults with prior lower urinary tract reconstruction utilizing bowel. Its efficacy and minimally invasive nature make it the approach of choice at our institution.

Abstract
Ureteral calculi management in patients with urinary diversion is challenging for most urologists. The surgeon should consider the patient's diversion type, BMI, stone size and location, and his/her experience with the procedure. We report an 85-year-old ileal conduit diversion man presented with ureteral calculi and treated via antegrade ureteroscopic lithotripsy.

Abstract
Background General anesthesia is used in the majority of patients undergoing percutaneous nephrolithotomy. To reduce the general anesthesia-related risks and complications, this study evaluated the efficacy and safety of the paravertebral block as a novel and alternative anesthetic method for percutaneous nephrolithotomy. Methods This was a retrospective study. A total of 198 patients under percutaneous nephrolithotomy were included. Among them, 76 patients received paravertebral block and 122 received general anesthesia. Patients' characteristics, surgical outcomes, anesthetic outcomes, and perioperative complications and the visual analog scale (VAS) were recorded to evaluate the efficacy and safety of paravertebral block compared with general anesthesia. Intergroup differences of the parameters were analyzed using an independent t-test and χ2-tests appropriate. Results Seventy-six patients who underwent paravertebral block completed the surgery successfully, three patients were supplemented with propofol for discomfort during ureteroscopy, and two patients were supplemented with remifentanil for incomplete nerve blockade. Patients who underwent paravertebral block had a higher American Society of Anesthesiologists grade and heart function grade, including patients with contraindications to general anesthesia. Intraoperative and postoperative adverse events and the anesthesia costs were less in patients who underwent paravertebral block. VAS pain scores during the postoperative period in patients who underwent paravertebral block were lower than those in patients who underwent general anesthesia without the use of patient-controlled intravenous analgesia. Conclusion In this retrospective study, paravertebral block was found to be effective and safe in providing intraoperative anesthesia for percutaneous nephrolithotomy, and had less adverse events and anesthesia costs. Paravertebral block is an attractive alternative anesthesia for patients at increased risk of comorbidities following general or neuraxial anesthesia.

Abstract
Background: Continent urinary diversion is a procedure commonly performed in patients after cystectomy who wish to not have a urostomy. Well-documented complications after continent urinary diversion include urinary tract infections and formation of urinary stones. However, these are typically late complications, and few reports have described the onset of these urinary symptoms within 12 months of initial continent urinary diversion. Case Presentation: Herein we report a case of a 41-year-old woman with history of cystectomy with continent urinary diversion who presents with recurrent infections and a calculus in the pouch 10 months after the initial procedure. Upon surgical exploration for removal of the stone, it was discovered that the stone was in fact a calcified retained catheter tip. Conclusion: This case further highlights that stone formation within 12 months of a urinary diversion is unusual and should prompt additional work-up for foreign body.

Abstract
Since their introduction into clinical practice in the 1950s, ileal conduits have been the most common type of urinary diversion used after radical cystectomy worldwide. Although ileal conduits are technically simpler to construct than other forms of urinary diversion, a variety of complications can occur in the early and late postoperative periods. Early complications include urine leakage, urinary obstruction, postoperative fluid collection (eg, urinoma, hematoma, lymphocele, or abscess), and fistula formation. Late complications include ureteroileal anastomotic stricture, stomal stenosis, conduit stenosis, and urolithiasis. Although not directly related to ileal conduits, ureteroarterial fistula can occur in patients with an ileal conduit. Interventional radiologists can play a pivotal role in diagnosis and management of these complications by performing image-guided minimally invasive procedures. In this article, the authors review the surgical anatomy of an ileal conduit and the underlying pathophysiology of and diagnostic workup for complications related to ileal conduits. The authors also discuss and illustrate current approaches to interventional radiologic management of these complications, with emphasis on a collaborative approach with urologists or endourologists to best preserve patients' renal function and maintain their quality of life. ©RSNA, 2020.

Abstract
INTRODUCTION AND OBJECTIVES The study was conducted to identify the risk factors of upper tract stone formation in patients with diversions after radical cystectomy (RC). MATERIALS AND METHODS All patients with diversion after RC were collected in our center from January 2005 to December 2013. Three different common diversions were included: Orthotopic neobladder (ON: 168 patients), Ileal Conduit (IC: 93 patients) or Ureterocutaneostomy (UC: 104 patients). Univariable and multivariable logistic regression analysis were conducted to identify the independent predictors of stone formation in the upper tract. RESULTS A total of 365 consecutive patients (316 males, 49 females) were included. At a median follow-up of 48 months (range 12-65 months), 36 patients (9.9%) developed upper tract stone. Among them, 26 (72.2%), 5 (13.9%) and 5 (13.9%) patients underwent ON, IC and UC, respectively. 25 patients had renal stone and 11 ureter stone. Minimally invasive operations (endoscopic laser lithotripsy via the anterograde or retrograde approach in 24 cases, percutaneous nephrolithotomy in 9 cases and shock wave lithotripsy in 3 cases) were carried out successfully in all stone cases. On univariable and multivariable logistic regression analysis, diabetes mellitus, hypertension, urinary tract infection (UTI), anastomotic stenosis and types of diversions (P<.05) were positively associated with upper tract stone formation. CONCLUSIONS The variable predictors of upper tract stone may contain diabetes mellitus, hypertension, UTI, anastomotic stenosis and types of diversion.

Abstract
OBJECTIVE We present our experience of the treatment of reservoir stones using a percutaneous approach in patients with Indiana pouch urinary diversions. MATERIAL AND METHODS Patients who were treated percutaneously for Indiana pouch reservoir stones between January 2008 and December 2018 were identified from the hospital database, and their data were retrospectively analyzed. Patient charts were reviewed for stone burden, surgery details, and postoperative complications. The Indiana pouch was punctured under a direct ultrasound guidance, and a 30F sheath was placed into the pouch. A urologist removed the stones by inserting a rigid nephroscope through the sheath. A Foley catheter was left in the pouch through the percutaneous tract and opened to drainage. RESULTS Seven patients (mean age: 47.3±14.7 years) were included. All patients were stone free after the procedure. The median stone number was 3 (range: 1-8). The mean maximum stone diameter was 24.4±4.9 mm (range: 19-33 mm). Six patients were successfully treated in one session, whereas 1 patient required two treatment sessions. The median postoperative hospital admission was 1 day (range: 1-5 days). The Foley catheters were removed after a median of 18 days (range: 10-19 days). No major complications were reported. CONCLUSION The percutaneous approach for Indiana pouch reservoir stones treatment ensures direct and safe management without major periprocedural complications.

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
Renal transplantation involving anatomically or functionally altered recipient urinary reservoirs is a challenging procedure. Initial reports discouraged kidney transplantation in patients with urinary diversion due to inferior outcomes. However, more recent studies have shown that although there are more infectious complications, patients with urinary diversions have comparable long-term graft survival with those with native anatomy. Careful preoperative assessment of these candidates is mandatory. Unique technical and surgical concepts must be considered before embarking on transplanting this specific cohort of kidney transplantation candidates.

Abstract
Kidney stones in patients with ileal conduit and multiple sclerosis are secondary to postoperative anatomical changes and ascending urinary tract infections by urea-splitting bacteria. PNL is the preferred treatment option in patients with urinary diversion and infectious renal stones.
