Evaluation of ureterointestinal anastomosis: Wallace vs Bricker

PURPOSE: There are no published reports to our knowledge comparing the complication rates of the 2 most frequently used ureterointestinal anastomoses. We compared the Bricker method vs the Wallace method in terms of stricture rate. MATERIALS AND METHODS: A retrospective review of the cystectomy database at our institution covering 1997 to 2003 was conducted. Patients were reviewed in terms of type of anastomosis, stricture formation, intervention, radiation therapy, type of diversion, operating room time, sex and age. RESULTS: A total of 237 patients at our institution underwent cystectomy during the time evaluated. Of these patients, 33 had incomplete data, 2 were anephric and did not require diversion, and 4 patients underwent LeDuc anastomosis. These patients were excluded from analysis, leaving 198 patients, 86 (43%) undergoing Bricker and 112 (56%) undergoing Wallace. Bricker anastomoses were considered 2 anastomotic units while Wallace anastomoses were considered a single unit. Therefore, there were 162 (59%) total Bricker anastomoses compared to 112 (41%) Wallace anastomoses. There was no statistically significant difference between the 2 groups in terms of type of diversion, number of patients undergoing adjuvant or neoadjuvant radiation therapy, operating room time, and days of followup. There were 3 strictures (1.85%) in the Bricker group and 5 strictures (4.46%) in the Wallace group. There was no statistically significant difference between the stricture rate in these 2 groups (p = 0.21). Stricture rates for patients undergoing neoadjuvant or adjuvant radiation were not statistically significant from the patients with no adjuvant therapy. CONCLUSIONS: Overall the stricture rate for ureterointestinal anastomosis was 2.92%. There was no difference in stricture rate between the 2 types of ureterointestinal anastomosis.     

Treatment of benign ureterointestinal anastomotic strictures with permanent ureteral Wallstent after Camey and Wallace urinary diversion: long-term follow-up

BACKGROUND AND PURPOSE: Ureterointestinal anastomotic stricture follows urinary diversion in 4% to 8% of patients and may lead to a progressive deterioration of renal function. There are problems with all current management techniques: surgical revision, endourologic incision, nephrostomy drainage, external ureteral stents, and dilation with a high-pressure angioplasty balloon. The authors present their long-term results with permanent ureteral Wallstents for the treatment of benign ureterointestinal stricture. PATIENTS AND METHODS: Eight patients with 10 strictures were treated by placement of self-expanding permanent indwelling stents via percutaneous nephrostomy between September 1993 and January 1998. The mean age of the group was 59.2 years. Development of strictures occurred a mean of 20.9 months after urinary diversion. There were seven complete and three partial strictures. Of 49 patients treated by the Camey procedure, 7 patients (14%) developed 9 (18%) strictures. Of 28 patients having the Wallace procedure, 1 patient (3.5%) developed one stricture. After recanalization of the distal ureter by a Terumo guidewire and dilation with a high-pressure angioplasty balloon, a Wallstent was placed across the stricture via a percutaneous approach. RESULTS: The endourologic placement of the Wallstent was well tolerated by all patients. The hospital stay averaged 2 days. Seven patients with nine strictures after the Camey procedure are doing well with a follow-up of 7 to 68 months (mean 22.4 months). One major complication was observed in one patient necessitating an additional procedure (lithotripsy) because of stone formation at the lower part of the stent extending into the neobladder in order to maintain patency after 68 months. The other patient, who had a Wallace procedure, is doing well 1 year 8 months afterward. CONCLUSION: An endourologic ureteral Wallstent approach to ureterointestinal stricture is a successful alternative, providing satisfactory management of the problem in most patients. No complication such as stent migration, hematuria, pain, or recurrent stricture was observed.     

The anterior ileal conduit: results of 100 consecutive cases

PURPOSE: The ileal conduit of Bricker is still widely used for urinary diversion after radical cystectomy for bladder carcinoma. We have modified the standard technique with the aim of reducing the complication rate and facilitating treatment. MATERIALS AND METHODS: We leave the conduit in its natural isoperistaltic anterior position, the ureters are anastomosed in an anterior position on their own side, using a short ileum segment. The incision of the peritoneum is made in a particular manner to allow on its closure to extraperitonealize the anastomoses and the bottom of the conduit and to support and fasten the loop. RESULTS: A total of 100 consecutive patients after radical cystectomy for bladder cancer had anterior ileal conduit. The complication rates were 5% temporary ureteroileal leakage, 1% reoperation rate, 5% long-term stenoses and 3% renal function deterioration. The surgical revision and the treatment of ureteroileal stenoses with anterograde percutaneous ureteral stenting were not complicated procedures. A comparison with conventional Bricker series shows a significant decrease in the complication rate. CONCLUSIONS: The anterior ileal conduit reduces the technique complication rate and facilitates the treatment of complications, and it is a recommended operation for these reasons.

膀胱全切原位回肠新膀胱术后输尿管肠吻合口良性狭窄的处理

目的：探讨膀胱全切原位回肠新膀胱术后输尿管肠吻合口良性狭窄的处理方法。方法：我科自2003年1月～2012年6月采用膀胱全切原位回肠新膀胱术治疗395例膀胱癌患者。术后发生输尿管肠吻合口良性狭窄10例,采用输尿管镜扩张、内镜下逆行／经皮穿刺顺行球囊扩张、内镜下狭窄段内切开、开放输尿管膀胱再植术,并留置双J管3～6个月。结果：本组10例中,1例（1处）因导丝不能通过狭窄段而改行开放手术,术后随访36个月,肾积水明显改善。其余9例（11处）采用腔内技术处理,其中3例（4处）采用输尿管镜扩张,2例（3处）采用内镜下狭窄段内切开,4例（4处）采用内镜下逆行／经皮穿刺顺行球囊扩张。术后随访9～72个月（中位25个月）。5例（7处）肾积水明显改善,2例（2处）肾积水长期随访无加重,2例（2处,狭窄段长分别为1．2cm、1．5cm）再发狭窄,遂采用开放手术,分别随访16及24个月,肾积水改善。结论：腔内技术操作简单,创伤小,可作为输尿管肠吻合口良性狭窄的首选治疗方案。开放手术仍然是治疗输尿管肠吻合口狭窄的金标准。对于狭窄段〉1cm的患者,应首先考虑开放手术。     

膀胱全切及双"拖入式"改良Bricker术治疗结核性膀胱挛缩和炎性尿道狭窄

目的探讨膀胱全切并双"拖入式"改良Bricker术治疗结核性膀胱挛缩和尿道狭窄的安全性及可行性。 方法回顾性分析2020年4月至2020年9月喀什地区第一人民医院诊治的4例结核性挛缩膀胱患者临床资料特征，总结该手术要点及步骤。4例男性患者（36~76岁），术前影像学及T-SPOT诊断为泌尿系结核，膀胱容量<40 ml，合并后尿道炎性狭窄。4例患者均施行挛缩膀胱切除并双"拖入式"改良Bricker术。术中取中下腹正中切口，先切除挛缩膀胱，术中膀胱颈部多点活检后最大限度保留膀胱颈口组织并封闭。双"拖入式"改良Bricker术步骤：游离输尿管并保护其血运，置入7 F尿流改道支架管并固定；距离回盲部20 cm以上，寻找血管分支适合的回肠段（15~18 cm），近端3-0可吸收线缝合封闭；直线切割闭合器回肠侧侧吻合；将取出的回肠段清洁；拖入右侧造口腹壁，回肠末端浆肌层与皮下组织缝合两次固定，形成自然乳头3 cm突出于皮肤；将输尿管"拖入式"错位植入回肠对侧系膜腔内。 结果手术时间131~178 min，术中出血为50~400 ml。术后5~7 d拔除尿流改道支架管，术后住院时间5~7 d，无严重并发症。术后随访3~8个月肾功能恢复良好，Bricker造口乳头满意。3例患者恢复正常性生活。 结论膀胱全切并双"拖入式"改良Bricker术可作为难治性结核性膀胱挛缩和尿道狭窄的手术选择方式，其远期安全性尚需进一步验证。

Our own experience in application of a combined percutaneous-retrograde approach for recanalization of the urethral structures in 4 patients in presented. Metallic guide is placed via the previously created percutaneous nephrostomy while dilatation or insertion of the metallic stent is performed retrogradely. The approach is used in the strictures in which percutaneou's placement of the recanalization balloon catheter into the stricture site was impossible. The method was successfully applied in all 4 cases in absence of any complications.
