Objective: To introduce a novel technique of ureterointestinal anastomosis for urinary diversion and report the preliminary clinical data.
Methods: Between June 2007 and June 2011, a total of 50 patients underwent radical cystectomy and ileal neobladder for invasive bladder carcinoma or carcinoma in situ. A novel, separate and direct end-to-end technique for ureteral reimplantation to the entrance of a segment of ileum was applied. in all patients. Details are as follow. The entrance of afferent loop was divided equally in to two lumens. Then each ureter was directly, end-to-end anastomosed to the above lumens respectively after lengthwise incisions for 1.5 cm. The mean follow-up period was 22 months (range, 3 - 48 months).
Results: Ureterointestinal anastomosis was performed successfully in 100 units. The operative durations were (18.4 ± 4.2) minutes. Ureteral stricture developed in 4 of 100 (4%) units and refluxing in 6 of 100 (6%) units. One patient with stricture was successful repaired by balloon dilation.
Conclusion: With low stricture and reflux rates, this novel procedure of ureterointestinal anastomosis is simple to handle and worthy of further promotion.

Introduction: Studies comparing refluxing versus non-refluxing ureteric implantation in continent cutaneous urinary diversion (CCUD) are scarce and often characterized by heterogeneous study populations. This work therefore aimed at comparing both techniques regarding long-term outcomes in a propensity-scored approach.
Methods: We identified n = 19 patients, totaling n = 38 renal units (RU), who underwent CCUD surgery at our hospital out of a pool of 120 patients.

Introduction: Benign ureterointestinal anastomotic stricture (UIAS) is a recognized long-term complication following radical cystectomy with urinary diversion (UD). The incidence of UIAS following robotic-assisted radical cystectomy varies, with reported rates ranging from 6.5%-25.

We reported radical cystectomy (RC), bilateral lymphadenectomy and orthotopic ileal neobladder reconstruction in a patient with history of kidney transplant. A 71-year-old man was referred to us with bladder tumor, elevated serum creatinine (1.9 mg/dl), hydroureteronephrosis in transplanted kidney and a 5-6-cm sessile mass in the right bladder wall with involvement of transplanted ureter orifice.

Background: Radical cystectomy (RC) has been considered the standard management of muscle-invasive bladder cancer. Despite the improvements in surgical techniques and perioperative care, RC is still associated with high perioperative morbidity and mortality.
Objective: This study aims to evaluate the effect of retroperitonealization of ureteroileal anastomosis on perioperative complications of RC with ileal conduit urinary diversion.

Background: We evaluated the feasibility and safety of stentless uretero-intestinal anastomosis (UIA) during radical cystectomy (RC) with an ileal orthotopic neobladder.
Methods: We retrospectively reviewed 403 patients who underwent RC for bladder cancer between August 2014 and December 2018. The primary objective was to study the effect of stentless UIA on uretero-intestinal anastomosis stricture (UIAS), and the secondary objective was to evaluate the association between stentless UIA and other complications, including paralytic ileus, febrile urinary tract infection (UTI), and urine leakage.
