Abstract
INTRODUCTION Urinary stone formation is a frequent complication after continent urinary tract diversion and can require complex surgical management. Therapy options include open, percutaneous, transurethral, or transstomal stone fragmentation and extraction. The transstomal approach is considered to be one of the more complex treatment modalities. The patient's individual anatomy, minor stoma diameter, and the existing continence mechanism in the majority of cases cause substantial technical challenges for the surgeon. We present here what we believe to be the first description of an analgesia-free flexible endoscopic removal of a large pouch stone in an out-patient care setting. Additionally, we provide a brief overview of competing techniques. CASE PRESENTATION A 30-year-old Caucasian woman with a history of lower urinary tract reconstruction with an ileal pouch and a continent umbilical stoma was admitted to our department with pouch urolithiasis in the urinary reservoir. We employed a minimally invasive approach to extract the stone using flexible ureteroscopy via a modified access sheath and laser lithotripsy. No analgesia is needed with this procedure and it can be performed in an out-patient setting. CONCLUSION The described clinical case highlights the difficulties of treating this high-incidence problem in patients with continent urinary diversions. Our presented technique is of particular interest to urologists and family doctors, and could improve the treatment of such patients by lowering the morbidity of the intervention.

Abstract
OBJECTIVE To present our experience in surgical management of urolithiasis in patients after urinary diversion. PATIENTS AND METHODS Twenty patients with urolithiasis after urinary diversion received intervention. Percutaneous nephrolithotomy, percutaneous based antegrade ureteroscopy with semi-rigid or flexible ureteroscope, transurethral reservoir lithotripsy, percutaneous pouch lithotripsy and open operation were performed in 8, 3, 2, 6, and 1 patients, respectively. The operative finding and complications were retrospectively collected and analyzed. RESULTS The mean stone size was 4.5 ± 3.1 (range 1.5-11.2) cm. The mean operation time was 82.0 ± 11.5 (range 55-120) min. Eighteen patients were rendered stone free with a clearance of 90%. Complications occurred in 3 patients (15%). Two patients (10%) had postoperative fever greater than 38.5 °C, and one patient (5%) suffered urine extravasations from percutaneous tract. CONCLUSIONS The percutaneous based procedures, including percutaneous nephrolithotomy, antegrade ureteroscopy with semi-rigid ureteroscope or flexible ureteroscope from percutaneous tract, and percutaneous pouch lithotripsy, provides a direct and safe access to the target stones in patients after urinary diversion, and with high stone free rate and minor complications. The surgical management of urolithiasis in patients after urinary diversion requires comprehensive evaluation and individualized consideration depending upon the urinary diversion type, stone location, stone burden, available resource and surgeon experience.

Abstract
PURPOSE We assess the feasibility, technique, complications and clinical outcomes of retrograde ureteroscopy in patients with orthotopic ileal neobladder. MATERIALS AND METHODS We retrospectively reviewed our ureteroscopy experience to identify procedures performed in patients who had previously undergone cystectomy with orthotopic ileal neobladder urinary diversion. These procedures were reviewed and data collected regarding patient characteristics, indication for endoscopic evaluation, surgical technique, findings, complications and followup. RESULTS Eight patients with neobladder diversion were taken for 9 sessions in the cystoscopy suite for attempted retrograde ureteroscopy on 13 renal units. The indication for ureteroscopy was an upper tract filling defect, positive cytology or calculi. The ureter and renal pelvis were successfully accessed and visualized in 10 of 13 renal units. The cause of failure in the 3 unsuccessful procedures was inability to access the ureteral orifice. Mean operative time +/- SD was 78 +/- 34 minutes. Urothelial abnormalities were identified in 4 patients, extrinsic compression in 2 and stones in 3. In 1 patient postoperative hematuria developed, which spontaneously resolved. Fluoroscopy was essential to identify the afferent limb of the reservoir, and a directional guide wire was helpful in engaging the ureteral orifice. CONCLUSIONS Ureteroscopic evaluation and treatment of upper tract abnormalities are feasible and practical in most patients with orthotopic neobladder urinary diversion. Identification of the ureteral orifice is challenging but can be accomplished with a combination of endoscopic and fluoroscopic techniques. This procedure avoids the morbidity of percutaneous access, and complications are minimal.

Abstract
PURPOSE OF REVIEW Patients who undergo urinary tract diversion are at an increased risk of urolithiasis for various reasons. The purpose of this article is to provide an up-to-date summary of the progress that has been made in the pathogenesis, diagnosis and treatment of stones in patients with urinary diversions. Finally, we will provide recommendations for follow-up in patients with urinary diversions who develop urinary tract calculi. RECENT FINDINGS In contemporary studies, the incidence of urolithiasis in patients with urinary diversion appears to be decreasing. Computed tomography scanning has been shown to be superior to ultrasound in the diagnosis of calculi in such patients. Endourological procedures have become the mainstay of therapy for stones in patients with urinary diversions. Since the introduction of extracorporeal shock wave lithotripsy, percutaneous nephrolithotripsy and ureteroscopy, the need for open surgery has decreased, even in this anatomically unique and surgically challenging patient population. SUMMARY Urolithiasis is an established long-term complication of urinary diversion. In recent years, significant advances have been made in the pathogenesis, diagnosis and treatment of such stones. As a result of potential stone-related complications, we recommend lifelong surveillance for all patients with urinary stones and diversions, with medical therapy when indicated, in order to minimize these complications.

Abstract
OBJECTIVE The purpose of this study was to review our experience with continent urinary diversions in patients with gynecologic malignancies and evaluate the presentation and management of early and late complications. METHODS A retrospective chart review was performed of all patients who underwent a continent urinary diversion on the Gynecologic Oncology Service at The University of Texas M. D. Anderson Cancer Center during the period January 1988 to March 2001. We analyzed our data to evaluate potential risk factors for complications. Renal status, conduit integrity, and overall patient outcomes were also studied. RESULTS We identified 40 patients who underwent a continent urinary diversion using an ileocolonic segment (Miami pouch technique). All patients had a history of gynecologic malignancies. The median age at the time of the procedure was 50 years (range 24 to 76 years), and the median weight was 69.6 kg (range 47 to 125 kg). A total of 39 patients (98%) had a history of radiotherapy. Continent urinary diversion was performed as part of an anterior pelvic exenteration in 12 patients (30%), in conjunction with a total pelvic exenteration in 18 patients (45%), and as the main procedure in 10 patients (25%). The median estimated blood loss was 2100 ml (range 200 to 8500 ml). The median length of hospitalization was 19.5 days (range 7 to 56 days). A total of 24 patients (60.0%) had a postoperative complications unrelated to the reservoir. Complications directly related to the continent urinary diversion were seen in 26 (65.0%) of 40 patients. None of the patients in this study group developed chronic renal failure, and there were no perioperative deaths. At last evaluation, 36 (90%) of 40 patients reported normal continent conduit function. CONCLUSIONS Continent urinary diversion using an ileocolonic segment is a reasonable alternative to the ileal and transverse colon conduit in bladder reconstruction in patients undergoing radical pelvic surgery. The routine use of postoperative total parenteral nutrition, the chronic use of antibiotics after discharge from the hospital, and the routine use of imaging studies remain controversial. In this group of patients, the majority of complications may be successfully managed conservatively.

Abstract
PURPOSE We review our initial cases of continent cystostomy to assess long-term functional results and complications after a minimum of 15 years of followup. MATERIALS AND METHODS Between 1976 and 1984, 23 continent cystostomies were performed on 15 boys and 8 girls with neuropathic bladders. Mean patient age at surgery was 8 years and 4 months (range 3 to 16) and mean followup was 20 years (range 15 to 23). The neurological lesions were due to 21 myelomeningocele (2 associated with an imperforated anus in 21 cases), spinal neuroblastoma in 1 and complex genitourinary malformation associated with an imperforated anus in 1. Closure of the bladder neck was performed in 21 cases (16 during the same procedure, 5 secondarily) and 2 did not undergo this procedure. The appendix was used as the catheterizable conduit in 20 cases, 1 ureter in 2 and a bladder tube in 1. Bladder augmentation was performed during the same procedure in 2 cases and at a later stage in 8. Five patients presented with unilateral or bilateral secondary vesicoureteral reflux. RESULTS One death occurred after conversion to cutaneous diversion due to a postoperative infection leading to a ventriculoperitoneal valve infection. The remaining 22 patients were followed every 6 to 12 months. No metabolic disorder, secondary malignancy or spontaneous bladder perforation was noted. Bilateral upper tract deterioration was found in 10 cases leading to secondary bladder augmentation by enterocystoplasty in 6 and creation of noncontinent diversion in 4. Leakage occurred after bladder neck closure in 5 patients. Bladder stones were found in 5 patients (2 had prior bladder augmentation). Complications related to the conduit included stomal stenosis or persistent leakage in 11 cases, which required surgical revision and/or repeated dilations and 1 noncontinent diversion after revision failure. Five patients presented with intestinal occlusion due to volvulus in 3 and adhesion in 2. We noted that after 10 years of followup complications were rare and concerned mostly the catheterizable conduit. Therefore, 16 patients had a good and stable result while 6 have noncontinent diversion. CONCLUSIONS The rate of complications has a tendency to decrease with time. The results obtained in this series may appear less satisfactory than those of more recent series, which may be due to the fact that these oldest continent cystostomies correspond to acquisition of experience of this novel approach, and to a period when the concept of low pressure reservoir was not yet established and bladder augmentations were not routinely performed. Since 1984 no continent cystostomy performed at our institution was converted into a noncontinent diversion. This series with long followup demonstrates that continent cystostomy is a procedure with lasting efficiency.

Abstract
BACKGROUND Endourologic management of stones and strictures in patients with a urinary diversion is often cumbersome because of the absence of standard anatomic landmarks. We report on our technique of minimally invasive management of urinary diversion-associated pathology by means of a combined antegrade and retrograde approach. PATIENTS AND METHODS Five patients with urinary diversion-associated pathology were treated at our institution between May 1997 and October 1998. Their problems were: an obstructing ureteral stone in a man with ureterosigmoidostomy performed for bladder extrophy; two men with a valve stricture in their hemiKock urinary diversions; an anastomotic stricture in a man with an ileal loop diversion; and a long left ureteroenteric stricture in a man with a right colon pouch diversion. After percutaneous placement of an guidewire across the area of interest, the targeted pathology was accessed via a retrograde approach using standard semirigid or flexible fiberoptic endoscopes. Postoperative follow-up with intravenous urography, differential renal scan, or both was performed at 3 to 24 months (mean 12 months). RESULTS The combined antegrade and retrograde approach allowed successful access to pathologic areas in all patients. Holmium laser/Acucise incision of stenotic segments or ballistic fragmentation of stones was achieved in all cases without perioperative complications. None of the strictures with an initially successful outcome has recurred; however, in one patient, the procedure failed as soon as the internal stent was removed. The patient with the ureteral calculus remains stone free, and his ureterosigmoidostomy is patent without evidence of obstruction on his last imaging study, 24 months postoperatively. CONCLUSIONS Combined antegrade and retrograde endoscopic access to the area of interest is our preferred method of approaching pathologic problems in patients with a urinary diversion. An antegrade nephrostogram provides better delineation of anatomy, while through-and-through access enables rapid and easier identification of stenotic segments that may be hidden by mucosal folds. Furthermore, this approach allows the use of larger semirigid or flexible endoscopes in conjunction with more efficient fragmentation devices, resulting in enhanced vision from better irrigation. Finally, an initial endoscopic approach may be preferred because its failure does not compromise the success of future open surgery.

Abstract
To various degrees, all continent pouch designs are subject to stones, which often are infected. We report on the endourologic management of large stone burdens in three types of continent reservoirs. Stone in a UCLA and a Kock pouch were managed endoscopically, and stones in an augmented pouch with a Mitrofanoff valve were managed percutaneously. Recommendations are made with regard to the optimal endourologic management of significant stone burdens in each of the common continent urinary reservoirs.
