Abstract
While upper tract access through the insensate conduit following urinary diversion takes less time and incurs fewer costs than percutaneous kidney access does for the treatment of ureter and kidney pathology, endoscopic ureteroenteric anastomoses (UEA) identification can be difficult. We injected India Ink into the bowel mucosa near the UEA during ileal conduit diversion (IC) to determine the safety and feasibility of ink tattooing. Patients undergoing IC were prospectively randomized to receive ink or normal saline (NS) injections. The injections were placed 1 cm from UEA in a triangular configuration, and loopogram exams and looposcopy were performed to identify reflux (UR), UEA, the tattooing site and strictures in 10 and 11 patients randomized with respect to ink and NS injections, respectively. Ink patients were older (72 vs. 61 years old, p = 0.04) and had a higher Charlson Comorbidity Index (5 vs. 2, p = 0.01). Looposcopy was performed in three ink and four NS patients. Visualization of UEA was achieved in 100% of the ink and 75% of the NS patients (p = 0.26). The ink ureteroenteric anastomotic stricture (UEAS) rate was higher (N = 3 vs. N = 1) and six patients vs. one patients underwent surgery, respectively, for UEAS (p = 0.31). The study was halted early due to safety concerns. Our pilot study demonstrates that ink can be well visualized following injection near UEA during IC. However, the ink cohort had more UEAS than previously cited in the literature and our prior institutional UEAS rate of 6%. While this study sample is small, the higher incidence of UEAS after ink injection led us to question the utility and safety of ink injection following IC.

Abstract
OBJECTIVES To analyse the risk of uretero-enteric anastomotic stricture in patients randomised to open (ORC) or robot-assisted radical cystectomy (RARC) with extracorporeal urinary diversion. PATIENTS AND METHODS We included 118 patients randomised to RARC (n = 60) or ORC (n = 58) at a single, high-volume institution from March 2010 to April 2013. Urinary diversion was performed by experienced open surgeons. Stricture was defined as non-malignant obstruction on imaging, corroborated by clinical status, and requiring procedural intervention. The risk of stricture within 1 year was compared between groups using Fisher's exact test. RESULTS In all, 58 and 60 patients were randomised to RARC and ORC, respectively. We identified five strictures, all in the ORC group. In patients with ≥1 year of follow-up, the increase in risk of stricture from open surgery was 9.3% (95% confidence interval 1.5%, 17%). Of the five strictures, three were managed endoscopically while two required open revision. There was no evidence that perioperative Grade 3-5 complications were associated with development of a stricture (P = 1) and no evidence of a difference in 24-month estimated glomerular filtration rate between arms (P = 0.15). CONCLUSIONS In this study at a high-volume centre, RARC with extracorporeal urinary diversion achieved excellent ureteric anastomotic outcomes. Purported increased risk of stricture is not a reason to avoid RARC. Future research should examine the impact of different surgical techniques and operator experience on the risk of stricture, especially as more intracorporeal diversions are performed.

Abstract
Objective: To evaluate the safety and efficacy of endoscopic procedures for ureteroenteric anastomotic strictures (UESs) after radical cystectomy and urinary diversion. Methods: We performed a meta-analysis of relevant articles through March 2020 using PubMed, Embase, and Cochrane Central Register to assess the efficacy of endoscopic procedures in UES according to the PRISMA and PICOS criteria. The main endpoints were success rate and complications, and we also compared the efficacy of different methods and stricture length and side in UES. Cochrane Collaboration's Revman version 5.3 and Stata version 15.1 software were used for statistical analysis. Results: A total of 18 retrospective studies with 697 patients were included. The median follow-up ranges from 12 to 62.5 months. Patients treated with endoscopic procedures had an overall success rate of 46%. The pooled rate of Clavien-Dindo ≥ 3 complications was 3.8% among included studies. Laser vaporization and stent insertion (48 and 47%) had a relatively high success rate than balloon dilatation (35%). In subgroup analysis, the success rate of endoscopic procedures for ≤ 1-cm strictures was significantly higher than that for >1-cm ones [odds ratio (OR), 8.65; 95% confidence interval (CI), 3.53-21.21; P < 0.00001]. In addition, the success rate in cases with strictures of the right side was relatively higher than that in cases with strictures of the left side (OR, 1.72; 95% CI, 1.05-2.81; P = 0.03). Conclusion: Our pooled studies showed that endoscopic operation is feasible and associated with a moderate success rate along with a relatively low incidence of perioperative complications in the treatment of UES, especially with length ≤ 1 cm and right side. Although there is still no consensus on endoscopic technique for UES regarding balloon dilatation, stent insertion, and laser vaporization, we believe that endoscopic management is a safety and available approach for UES with close follow-up.

Abstract
Objective: To present our technique of ureteroileal bypass to treat uretero-enteric stric- tures in urinary diversion. Materials and Methods: One hundred and forty-one medical records were reviewed from patients submitted to radical cystectomy to treat muscle-invasive bladder cancer between 2013 and 2015. Twelve (8.5%) patients developed uretero-enteric anastomotic stricture during follow-up. Five patients were treated with endoscopic dilatation and double J placement. Four were treated surgically with standard terminal-lateral im- plantation. Three patients with uretero-enteric anastomotic stricture were treated at our institution by “ureteroileal bypass”, one of them was treated with robotic surgery. Results: All patients had the diagnosis of uretero-enteric anastomotic stricture via computerized tomography and DTPA renal scan. Time between cystectomy and diag- nosis of uretero-enteric anastomotic stricture varied from five months to three years. Mean operative time was 120±17.9 minutes (98 to 142 min) and hospital stay was 3.3±0.62 days (3 to 4 days). Mean follow-up was 24±39.5 months (6 to 72 months). During follow-up, all patients were asymptomatic and presented improvement in ure-terohydronephrosis. Serum creatinine of all patients had been stable. Conclusions: Latero-lateral ureter re-implantation is feasible by open or even robotic surgery with positive results, reasonable operation time, and without complications.

Abstract
Approximately 9.2% of patients who undergo radical cystectomy are reported to develop ureteral stricture as a result of both benign and malignant conditions. A metallic stent is a continuous, unfenestrated all-metal double-pigtail ureteric stent with no end or side holes. The patient was a 74-year-old man who underwent radial cystectomy with the creation of an ileal conduit due to advanced bladder cancer 7 years previously. Although he had no radiographic recurrence, he developed bilateral hydronephrosis. We herein report the first case of a patient with ureteral stricture after radial cystectomy with the creation of an ileal conduit who was successfully treated by the insertion of a metal stent by a combined antegrade and retrograde approach.

Simultaneous antegrade and retrograde endoscopic treatment of non-malignant ureterointestinal anastomotic strictures following urinary diversion. BMC Urol 2017; 17:61. [PMID: 28789635 PMCID: PMC5549397 DOI: 10.1186/s12894-017-0252-0] [Citation(s) in RCA: 6] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/03/2017] [Accepted: 08/03/2017] [Indexed: 11/17/2022] Open
Abstract
Background The ureterointestinal anastomosis stricture (UAS) is a common complication of urinary diversion after radical cystectomy. For decades, open anastomotic revision remained the gold standard for the treatment of UAS. However, with the advancement in endoscopic technology, mini-invasive therapeutic approaches have been used in its management. Here, we report our experience with and long-term results of combined simultaneous antegrade and retrograde endoscopy (SARE) in the treatment of non-malignant UASs after urinary diversion in a consecutive series of patients. Methods From March 2012 to January 2015, there were 32 consecutive patients with 32 non-malignant UASs following radical cystectomy and urinary diversion. Twenty-nine patients were treated with SARE technique and comprised the study group. Using simultaneous antegrade flexible ureteroscope combined with retrograde semi-rigid ureteroscope or nephroscope, partial or complete strictures were managed with laser incision and balloon dilation under direct visualization. A 7/12 Fr graded endopyelotomy stent was left for 3–6 months after the procedure. Success was defined as symptomatic improvement and radiographic resolution of obstruction. Results With a median followup of 22 months (6–36), the overall success rate for SARE was 69.0%. Twenty patients with partial stricture had a success rate of 85%, and 9 patients with complete stricture had a success rate of 33.3%. Renal function, hydronephrosis grade, stricture type, and stricture length were significant influences on the outcome (P < 0.05). No complication was observed. Conclusions The SARE is a safe and effective treatment for UAS, and may be the only endoscopic treatment approach for complete UAS. While success rate for complete strictures is low compared to open revision, it should be considered as an initial approach given its low overall morbidity. For partial strictures, prudent patient selection results in higher success rates that are nearly comparable to open revision.

Abstract
Radical cystectomy and urinary diversion is the gold-standard treatment for muscle-invasive and high-risk non-muscle-invasive bladder cancer. Ureteroenteric anastomotic stricture is a well-known complication of urinary diversion and is associated with serious sequelae that lead to total or partial loss of kidney function, infectious complications, and the need for additional procedures. Although the exact aetiology of benign ureteroenteric anastomotic strictures is unclear, they most likely occur secondary to ischaemia at the anastomotic region. Diagnosis can be achieved using retrograde contrast studies, CT scan or MAG3 renography. Open revision remains the gold-standard treatment for ureteroenteric anastomotic strictures; however, endourological techniques are being increasingly used and, in select patients, might be the optimal approach.

Abstract
Background and Aims: The aim of this study was to compare the feasibility and early postoperative outcomes between patients undergoing double-barreled wet colostomy and patients undergoing terminal colostomy and ileal conduit for simultaneous urinary and fecal diversion. Material and Methods: Between 1995 and 2012, we had 181 patients in whom it was necessary to make simultaneous urinary and fecal diversion. This is a retrospective study and patients were divided into two groups, depending on the technique applied for the fecal and urinary diversion. The first group consisted of patients undergoing ileal conduit and terminal colostomy and the second group consisted of patients undergoing double-barreled wet colostomy. Results: Ileal conduit and terminal colostomy was performed in 77 (43%) cases, while wet colostomy was performed in 104 (57%) cases. Median length of stay was shorter for double-barreled wet colostomy (13.1 vs 18.1, p < 0.0001). Median operating times for urinary and fecal diversion were shorter for double-barreled wet colostomy (32 vs 64 min, p < 0.0001). The morbidity was lower for double-barreled wet colostomy (11.5% vs 23.4%, p = 0.0432), retrospectively. The mortality was 3.8% for double-barreled wet colostomy and 10.3% for ileal conduit and terminal colostomy group (p = 0.1282). Conclusions: Double-barreled wet colostomy is a safe, fast, and simple alternative to traditional ileal conduit and terminal colostomy diversion. The technique is relatively easy to learn, and it reduces the time for urinary and fecal diversion, length of stay, and morbidity rate.

Abstract
PURPOSE We compared the long-term results of minimally invasive endourological intervention and open surgical revision in patients with a nonmalignant ureteroileal stricture. MATERIALS AND METHODS We retrospectively evaluated the records of 74 patients (85 renal units) treated for unilateral or bilateral nonmalignant ureteroileal strictures. Overall, 96 endourological and 35 open surgical procedures were performed. Balloon dilatation and Acucise® or Ho:YAG laser endoureterotomy were used as minimally invasive endourological interventions. Open surgical revision with stricture resection and open ureteroileal end-to-side-reanastomosis was the alternate therapy. Treatment success was defined as radiological normalization or improvement of upper urinary tract morphology combined with absent flank pain, infection, ureteral stents or percutaneous nephrostomies. RESULTS Median followup was 29 months (range 2 to 177). The overall success rate was 26% (25 of 96 cases) for endourological intervention vs 91% (32 of 35) for open surgical revision (p <0.001). Subgroup analysis showed a significant difference in the success rate of minimally invasive endourological interventions vs open surgical revision for strictures greater than 1 cm (3 of 52 cases or 6% vs 19 of 22 or 86%, p <0.001). The success rate of endourological and open surgical procedures for strictures 1 cm or less was 50% (22 of 44 cases) and 100% (13 of 13), respectively. After adjusting for multiple preoperative stricture characteristics, only stricture length was strongly and inversely associated with a successful outcome (p <0.001). CONCLUSIONS Open surgical revision produces better results than minimally invasive endourological intervention for ureteroileal strictures, particularly those greater than 1 cm. The success rate of endourological intervention is acceptable only for ureteroileal strictures 1 cm or less. Therefore, ureteroileal strictures greater than 1 cm should be primarily managed by open surgical revision.

Experience with ureteroenteric strictures after radical cystectomy and diversion: open surgical revision. Urology 2011; 78:459-65. [PMID: 21492915 DOI: 10.1016/j.urology.2011.01.040] [Citation(s) in RCA: 52] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/09/2010] [Revised: 01/18/2011] [Accepted: 01/18/2011] [Indexed: 11/22/2022]
Abstract
OBJECTIVES To evaluate the long term results of the treatment of benign ureteroenteric strictures as a serious complication after urinary diversion and to highlight on the precautions for the active intervention. The outcomes of endoureteral and open surgical revisions in our patients are described. METHODS Of 658 patients who had undergone radical cystectomy for bladder cancer from 1999 to 2009, 58 had developed benign stricture. The diversions used in this subgroup were orthotopic neobladder (53.4%), ileal conduit (27.6%), and ureterocolic (19%). The median interval to the diagnosis was 6 months, and 63.8% were on the left side. Endouretral interventions (dilation and stent or endoureterotomy) were the initial treatment in 37 patients. Thirty-two patients including patients who failed endoluminal interventions and patients with bilateral strictures underwent open surgery. Success was defined as radiologic improvement and the absence of flank pain, infection, or the need for a ureteral stent or nephrostomy tube. RESULTS Endoscopic intervention was successful in 19 (51.3%) of 37 patients, principally those with strictures <1 cm with no difference between side, diversion type, or implantation technique. A total of 32 patients underwent open stricture resection and repair by direct implantation or tissue interposition to bridge long defects (6 Boari flaps and 7 ileal segments). At a median follow-up of 47 months, 25 patients had long-term success (78%) and 36 (83.7%) of 43 repaired units had improvement. Improvement was superior for right-sided strictures compared with left-sided strictures (100% vs 75.8%) and for neobladder compared with other diversions (90% vs 69%). Both anastomotic and ureteral strictures were repaired with equivalent results (87.5% vs 82.8%). CONCLUSIONS Although endouretral procedures are viable treatment alternatives, open surgical revision is the preferred long-term definitive treatment. Bilateral and long left-sided strictures >1 cm long are indications for early open surgery.

Abstract
PURPOSE Open surgery after cystectomy can be a challenge. We report the incidence of postoperative urinary diversion-enteric fistula and ureteral strictures in patients undergoing radical cystectomy, and discuss the diagnosis and management of these complications, including our surgical approach to these patients. MATERIALS AND METHODS We preformed a retrospective review of 553 patients undergoing radical cystectomy and urinary diversion for bladder cancer between April 1999 and January 2007. Patients in whom a ureteral stricture or fistula developed were identified by serial laboratory and imaging evaluations. A chart review was preformed to identify symptoms, time to stricture or fistula development, radiological findings, type of diversion, estimated blood loss and whether the original anastomosis was stented. Management and outcomes were assessed. RESULTS Of 553 patients reviewed ureteral stricture developed in 41 (7.4%) with a mean followup of 20.2 months (range 1 to 98). Strictures developed in 11% (31 of 272) of the orthotopic ileal neobladder, 2.5% (6 of 236) of ileal conduit and 8% (4 of 45) of Indiana pouch cases. Open repair led to an overall success rate of 87%. Urinary diversion-enteric fistula developed in 12 (2.2%) of the 553 patients with a mean followup of 28.4 months (range 3 to 94), all of whom had undergone orthotopic neobladder diversion. No patient had recurrence after surgical repair of the fistula. CONCLUSIONS Open revision remains the gold standard management for ureteral strictures and urinary diversion-enteric fistulas occurring after radical cystectomy. The addition of the chimney modification to the orthotopic neobladder facilitates surgical repair.

Abstract
Up to 10% of patients who undergo ileal conduit urinary diversion may go on to develop ureteroileal anastomotic stenosis (UIAS); this can lead to recurrent urinary tract infections and deterioration in renal function. Classical management has been open revision of the anastomosis. We describe a novel technique that allows balloon dilatation and ureteral stent placement in a retrograde fashion. All patients in this study had undergone radical cystectomy and ileal conduit formation with Wallace type end-to-end refluxing uretero-intestinal anastomosis. After initial retrograde loopogram, a 6F MPA-1 catheter and an 0.035 inch extra stiff guide was passed to the distal ostium. Subsequently, a customised 8F bright tip MPA-1 guiding catheter was advanced over the guide wire which allowed effective splinting of the equipment to facilitate greater control of a second catheter and guide wire combination to access the stenotic or occluded anastomosis. Results show that a total of ten anastomoses were treated; nine anastomoses were successfully treated with a primary retrograde approach with no intra or post-procedural complications. After a mean follow-up of 19 months (5-33 months), as assessed by ascending loopograms, all anastomoses remained open. In conclusion, morbidity of open surgery has resulted in the popularization of endourological techniques in treating anastomotic stenoses. However, key to these endourological techniques is access to the anastomosis; typically, this has been via a percutaneously placed nephrostomy. The ideal route to the anastomosis is via a retrograde approach; we have illustrated a safe and successful novel technique that utilized two guidewires and a guiding catheter, allowing retrograde ureteral access.

Abstract
PURPOSE We describe a new surgical endoscopic technique for nonmalignant ureterointestinal anastomotic strictures. This procedure involving endoureterotomy by intraluminal invagination (the Lovaco technique) is performed by adopting a combined percutaneous antegrade and endoscopic retrograde approach. The results obtained by this technique are reviewed with long-term followup. MATERIALS AND METHODS A total of 25 ureterointestinal anastomotic strictures were subjected to endoureterotomy by intraluminal invagination, including 12 left, 7 right and 3 bilateral cases. Surgical success was defined by radiological improvement and/or the ability to recover normal activity in the absence of flank pain, infection, or the need for ureteral stents or nephrostomy tubes. RESULTS At a median followup of 51 months (range 2 to 145) the success rate for endoureterotomy by intraluminal invagination was 80% (20 of 25 ureterointestinal anastomotic strictures). No complications were recorded in the patients following endoureterotomy. CONCLUSIONS This new endoureterotomy technique for ureterointestinal strictures following urinary diversion can be applied to any type of urinary diversion. It allows direct visualization of the stricture and stricture tissue biopsy. Intraluminal invagination makes it possible to increase the distance between the stricture, and the retroperitoneal vessels and bowels. The technique provides the control required to ensure full-thickness and full-length stricture incision. The success rate is high and it persists after long-term followup.

Abstract
PURPOSE To summarize the status of endoscopic treatment for ureterointestinal anastomotic strictures after radical cystectomy. MATERIALS AND METHODS We reviewed the English-language literature identified by PubMed and MEDLINE to evaluate the efficacy of various treatment options for these strictures. RESULTS Cumulative success rates from multiple studies analyzing patency after balloon dilation, endoureterotomy, and metal stenting specifically for ureteroenteric strictures were 18%, 63%, and 83%, respectively. Studies have not clearly shown any significant advantage over any specific cutting modality. The use of metal stents appears promising but is still fraught with complications of tissue ingrowth and recurrent obstruction. Clinical factors that appear to be associated with a poor prognosis are age >60 years, left-sided strictures, length >1 cm, stenting <4 weeks, and poor function in the affecting kidney. CONCLUSION Ureteroenteric strictures remain the most challenging and difficult of all ureteral strictures to treat. An evolution of technology has helped advance the therapeutic options available. Given the rarity of this condition, limited study designs, and small numbers of patients, conclusive statements regarding the optimal treatment for this condition are difficult. Given its patency rates and possible complications, endoureterotomy should be considered the initial treatment of choice in properly selected patients.

Abstract
OBJECTIVE To highlight the current status of ureteroscopic endoureterotomy (UE) by reporting extensive experience with the endoscopic management of ureteric strictures, with special emphasis on factors determining success, and by reviewing publications on the minimally invasive management of ureteric strictures. PATIENTS AND METHODS The study comprised 50 patients (mean age 53 years, range 18-85, equal sex distribution) with ureteric strictures of varying causes; all had their stricture treated endoscopically. The follow-up was 0.5-9 years; 10 patients with recurrent strictures had two ipsilateral stents placed to try to improve the outcome, and eight patients with completely obliterating strictures were treated by ureteroscopic re-canalization. RESULTS The site of stricture had no bearing on the eventual outcome. Patients with uretero-enteric and malignant strictures did not fare so well. The most important predictor of failure was the length of the stricture, with failure in all seven patients with strictures of > 2 cm. In the 10 patients treated with two ipsilateral stents, eight were successful, which was very promising considering that these patients had recalcitrant strictures and placing one stent had previously failed. The overall success rate was 74%. CONCLUSION UE has become the procedure of choice for the initial management of ureteric strictures. Simple balloon dilatation is also effective in certain situations. The characteristics of the stricture often govern the eventual outcome. In properly selected cases success rates of approximately 75% can be expected.

Abstract
OBJECTIVE To evaluate the outcome of patients with continent urinary diversions who had a solitary functioning kidney at the time of surgery. PATIENTS AND METHODS In all, 62 patients with continent urinary reservoirs and a solitary functioning kidney were reviewed (51 men and 11 women). The indications for surgery were bladder cancer in 54 and a contracted bladder in eight. The surgical procedures included an orthotopic ileal neobladder in 36 patients, a continent cutaneous ileal reservoir in 13 and rectal diversion in 13. Kidneys were evaluated using serum creatinine level, ultrasonography, intravenous urography and other radiological studies. RESULTS The follow-up was 6-173 months; 44 renal units (71%) remained stable during this period. Serum creatinine was increased in four patients with an orthotopic neobladder, with no evidence of obstruction or reflux, in one with preoperative renal impairment and one with voiding dysfunction, reflux and bacteriuria. Six renal units deteriorated because of uretero-intestinal strictures; of these patients, two were treated endoscopically, two with open ureteric reimplantation, one with conversion from a rectal reservoir to an ileal loop conduit, and one was maintained on JJ stenting. Six patients with a rectal diversion had renal deterioration because of chronic pyelonephritis. CONCLUSIONS A regular follow-up of renal function is mandatory in patients with a continent urinary diversion. Rectal diversion is associated with a higher risk of renal deterioration (54%) than are orthotopic (28%) and cutaneous reservoirs (8%).

Abstract
PURPOSE Prior studies have demonstrated that while endoureterotomy offers a reasonable initial treatment option, open anastomotic revision should remain the gold standard for managing ureteroenteric strictures. However, to our knowledge the results of contemporary endoureterotomy series have not been compared with those of open anastomotic revision, and no study has assessed the morbidity or success rate of secondary open anastomotic revision after failed endoureterotomy. MATERIALS AND METHODS Between May 1997 and August 2002 a total of 31 renal units in 22 patients were treated for ureteroenteric strictures after radical cystectomy and urinary diversion. A total of 16 renal units were treated endoscopically, including 9 on the left and 7 on the right side, and open revision was performed in 15 renal units, including 9 on the left and 6 on the right side. Success was defined as radiological improvement and/or the ability to return to full activity in the absence of flank pain, infection, or the need for ureteral stents or nephrostomy tubes. RESULTS At a median followup of 35 months (range 17 to 62) for endoureterotomy and 34 months (range 5 to 54) for open revision the success rate of endoureterotomy and open revision was 50% (8 of 16 renal units) and 80% (12 of 15), respectively. One of the 3 patients in whom open revision failed underwent prior pelvic external beam radiation and the other 2 underwent prior endoureterotomies. Overall interventions for right strictures were more successful 85% or 11 of 13 cases than those on the left side (50% or 9 of 18) (p = 0.037). Average operative time was longer and average estimated blood loss was higher in patients treated with open repair after failed endoureterotomy (p = 0.009 and 0.016, respectively). No complications developed in patients following endoureterotomy. CONCLUSIONS Open revision remains the gold standard for the management of ureteroenteric strictures. Left strictures are considerably more resistant to management. Patients with left anastomotic strictures should be cautioned that endoureterotomy might have a lower success rate, and failure may limit the success and increase the morbidity of subsequent open anastomotic revision.

Abstract
PURPOSE We describe a modification of the cut to the light and core-through procedures using a laser fiber to gain through and through access for treatment of complete occlusion of the ureter or urethra. MATERIALS AND METHODS Three patients presented with complete obliteration of the ureter (2) and vesicourethral anastomosis (1). In each case the laser fiber was advanced through the obliterated segment under direct vision and then exchanged for a standard guide wire using an open ended catheter. RESULTS Through and through access was obtained in all 3 cases and allowed subsequent incision for repair. In all 3 patients the area of incision was stented and urinary continuity was restored. CONCLUSIONS Loss of access can lead to complications and termination of any endoscopic procedure. Use of the laser fiber to incise through the obliterated segment and subsequently act as a guide wire in our experience minimized the possibility for loss of access. The disadvantage is the cost of the laser fiber, which cannot be reused. Use of a laser fiber as a guide wire can be a viable and effective option for gaining access across strictures when alternative methods fail.

Abstract
OBJECTIVES To evaluate the long-term results of cold-knife incision (CNI) of nonmalignant ureterointestinal anastomosis strictures (UASs) after urinary diversion in a consecutive series of patients. METHODS Since 1994, we have evaluated retrospectively 40 patients with 43 UASs, who were primarily treated with CNI (group 1). Six patients from group 1 with 7 UASs who failed primary CNI comprised group 2. After placement of an 8F nephrostomy tube, a 0.035-inch guidewire bypassed the stricture in an antegrade fashion under guidance of a centrally opened ureteral catheter (5F). A wire-mounted cold-knife was pulled through the strictured area in retrograde fashion under fluoroscopic control. Postoperatively, an 8 to 12F stent was left indwelling for 6 to 12 weeks. Successful treatment was defined as radiographic and scintigraphic resolution of obstruction and symptomatic relief. RESULTS In group 1, after removal of the stent, the ureteroenteric area remained patent in 26 (60.5%) of 43 UASs during a follow-up period of 38.8 months (range 12 to 85). The success rate at 1, 2, and 3 years was 86%, 67.8%, and 60.5%, respectively. In group 2, no success occurred. The diameter and length of the stricture, kidney function, hydronephrosis grade, presence of urinary infection at presentation, past CNI or radiotherapy, number of incisions with the cold-knife, and premature appearance of the anastomosis stricture were statistically significant influences on the outcome (P <0.05). Considering only the patients (n = 8) with the most favorable predictive factors (interval to stricture formation 12 months or longer, stricture length 1.5 cm or less, and hydronephrosis grade I-II), the success rate was 100%. No complications were observed. CONCLUSIONS CNI is an effective and minimally invasive treatment for primary UASs, providing durable results compared with other modalities used for endoureterotomy, and should be considered as an initial approach. The selection of patients with the most favorable prognostic factors leads to excellent results. As a secondary procedure, CNI was not successful.

Abstract
UNLABELLED We report our experience in the treatment of uretero-enteric anastomotic strictures. Our incidence in this complication is 3.8% in orthotopic bladder substitution and 8.3% in ileal conduict. MATERIAL AND METHODS We have treated this complication in 6 patients with orthotopic bladder substitution and 4 with ileal conduict. We tried to perform a dilatation with a high pressure balloon and to place a Double-J catheter. RESULTS In 4 cases we could not introduce the guidewire through the stricture because there was a total stop. In the others 6 cases, one is doing well without Double-J, another one did not tolerate the catheter and we performed an open surgical reanastomosis, 2 kept the catheters until their death due to metastases and the other two continue alive with their catheter periodically replaced. CONCLUSIONS The direct uretero-enteric anastomoses present less stenoses risk. Endourological techniques should be the first option in treatment of these patients.

Abstract
PURPOSE The functional results and complications of 2 different ureteroileal anastomoses were evaluated in patients with bladder cancer undergoing radical cystectomy and orthotopic ileal bladder substitution. MATERIALS AND METHODS Between 1989 and 1995, 102 patients underwent creation of a low pressure neobladder. In the first 50 cases the ureteroileal anastomosis was created with a split-cuff nipple technique as an additional antireflux mechanism. In the next 52 cases the ureteroileal anastomoses were constructed via the direct end-to-side technique counting on the antireflux protection of the afferent tubular limb. RESULTS Stenosis occurred in 7 of the 100 ureters (6 patients) treated with the split-cuff nipple technique and 7 of 104 treated with a direct end-to-side anastomosis. This complication occurred more commonly in the left ureter (11 of 14 patients). Reflux was noted at cystography in 10 cases with the split-cuff nipple method and 12 with end-to-side anastomoses, and was symptomatic in only 3 patients. Four ureteral strictures were treated successfully with primary open repair. Percutaneous dilation and stenting were performed for 8 ureteral strictures: 2 cases were successful, 3 failed and 3 are unresolved. CONCLUSIONS We observed no differences between the antireflux split-cuff and end-to-side anastomoses with regard to stricture formation or ureteral reflux. Therefore, we do not believe that there is a need to create antireflux ureteral anastomoses due to the tubular afferent ileal segment and given that the reflux is asymptomatic in most patients. Strictures may be treated with percutaneous balloon dilation and stenting but open repair appeared to be more effective.

Abstract
OBJECTIVE To evaluate the glomerular filtration rate (GFR) and incidence of anastomotic stenosis in patients with urinary diversion by ileal or colonic conduit (refluxing or anti-reflux uretero-intestinal anastomosis) or with a continent caecal reservoir. PATIENTS AND METHODS All conduit urinary diversions performed from 1977 to 1984 were randomized by type (ileal or colonic) and by the method of ureteric implantation (with or without anti-reflux technique). In continent caecal reservoirs anti-reflux implantation was used for both ureters. Total and separate GFR were measured pre-operatively and after a mean follow-up of 123 months (range 36-198) with 51Cr-EDTA and scintillation renography. RESULTS Of the 56 evaluable patients, 18 had an ileal and 20 a colonic conduit, and 18 had a continent reservoir. The total mean GFR fell from 88 to 71 mL/min in the ileal group, from 84 to 65 mL/min in the colonic group and from 100 to 85 mL/min in the reservoir group. Separate GFR did not differ significantly between kidneys with and without reflux protection in the patients with a conduit diversion. Strictures occurred in 15 uretero-intestinal anastomoses and were unrelated to the mode of ureteric implantation (in the conduit groups). Renal function improved after ureteric reimplantation in six of seven kidneys, but after balloon dilatation in only one of five. CONCLUSION GFR fell moderately in all three groups, with no significant intergroup difference, and the continent caecal reservoir compared favourably with conduit diversion. The fall in separate GFR did not differ significantly between kidneys with and without reflux protection. Surgical exploration of uretero-intestinal stenosis is recommended if renal function is threatened.

Abstract
We present a technique used in two patients with Bricker urinary diversion for the approach of ureteroileal anastomosis. The right lateral extraperitoneal approach provides fast access to the site, is virtually bloodless and appears to have no major complications. Although this method is extensively used by urologists, it does not appear in the literature on repairs of ureteroileal strictures.
