Aim: To present the results and technical features of forming the ureterointestinal anastomoses in intestinal ureteral substitution.
Material And Methods: From 1998 to December 2016, 168 patients (mean age 51 +/- 8.7 years) underwent ureteral substitution using intestinal segments at the Urology Clinic of the I.I. Mechnikov NWSMU. Of them, 76 (45.2%) were males. In 119 (70.8%) patients, intestinal segments were used to replace various parts of the ureters (iliac in 92, colonic in 4, appendix in 23), and in 49 (29.2%) patients ureteroplasty was combined with orthotopic ileocystoplasty. 96 patients underwent isolated ureteral substitution with segments of the small and large bowel.
Results: Among the 96 patients, early postoperative complications occurred in 8 (8.3%) patients, whereof 5 (5.2%) required reoperations. Among them, 2 (2.1%) had a proximal anastomotic failure. Late postoperative complications occurred in 7 (7.3%) patients whereof 4 (4.2%) required surgical treatment. These patients developed strictures of the proximal ureter-intestinal anastomoses over 3 or more months after the operation. The urinary flow was restored by antegrade dilation. Vesicoureteral reflux occurred in 2 (2.1%) patients. However, it was not clinically evident and was not accompanied by hydroureteronephrosis and recurrent urinary tract infection.
Conclusion: A perfect ureterointestinal anastomoses should be easy to create and have a low risk of stenosis and reflux. These requirements are met by direct anastomosis, which is associated with a minimal risk of stricture, and with isoperistaltic positioning and sufficient length (not less than 15 cm) of the graft provides antireflux protection. It should be noted that proximal (ureterointestinal) anastomoses are vulnerable in these operations and prone to the stricture formation. Unlike proximal, the distal anastomosis of the graft with the bladder is always wider, and therefore the risk of its narrowing is minimal. Isoperistaltic positioning of the graft prevents reflux formation.

Aim: To present the results and technical features of forming the ureterointestinal anastomoses in intestinal ureteral substitution.
Material And Methods: From 1998 to December 2016, 168 patients (mean age 51 +/- 8.7 years) underwent ureteral substitution using intestinal segments at the Urology Clinic of the I.
147 patients who underwent urinary intestinal diversion from 2004 to 2014 were selected for the retrospective study. The authors carried out a comparative analysis of rates of complications that arise from the direct ureterointestinal anastomosis. The mean age of patients was 54.

Objective: To evaluate the long-term renal function, continence, and voiding function in 64 patients, surviving for 5 or more years after W-shaped ileal neobladder with a short afferent limb and refluxing ureterointestinal anastomoses.
Materials And Methods: Kidney morphology and function were evaluated using nuclear renography, creatinine, and glomerular filtration rate. Continence and voiding function were evaluated with a diary on frequency, voided volumes, number of pads, and with the incontinence severity index (ISI) questionnaire, the American Urological Association-Symptom Index (AUA-SI), and the American Urological Association-Symptom Problem Index.

Purpose: Benign ureterointestinal anastomotic stricture is not uncommon after radical cystectomy and urinary diversion. We studied the impact of the running vs the interrupted technique on the ureterointestinal anastomotic stricture rate.
Materials And Methods: From July 2007 to December 2008 interrupted end-to-side anastomoses were created and from January 2009 to July 2010 running anastomoses were created.
Unlabelled: Substitution of the bladder with segment of the digestive tract, within the radical treatment of bladder cancer, as well as treatment of the other bladder abnormality, is extremely demanding surgical procedure, that aims adequate treatment of the underlying disease and provide patient's renal function within physiological level. Surgical implantation of the ureter into the intestinal segment are an important part of the surgical technique, the formation of ileal conduit, with the ultimate aim of providing a more natural way of evacuation of urine from the upper urinary tract in terms of maintaining the adequate quality of renal function. Which of the existing surgical method of implantation of ureter in the intestinal segment will be applied, it is for urologist to decided, according to his affinity and/or his operating school of origin.
