Uretero-intestinal anastomoses: which method to choose? History, current state of the issue and own experience

Introduction. At the moment, after performing a cystectomy, one of the most urgent issues remains the choice of technique for performing uretero-intestinalanastomoses.Materials and methods. The search of the information was conducted in the Pubmed and Scopus databases, with a scientific electronic library Elibrary.ru andwebsites of professional urological and oncological associations. The search was performed for the keywords «Radical cystectomy», «uretero-intestinal anasto-mosis», «bladder cancer», and «neobladder». For citation in the article, 44 publications were selected. We also present our own data - long-term functional results of radical cystectomy for muscle-invasive bladder cancer for the period from 2016 to 2020. Results. The article presents a literature review on the development of modern methods for creating uretero-intestinal anastomoses in various clinical situations.The methods are presented in chronological order of their description in the literature, indicating the advantages, disadvantages and long-term results. In all 75 cases included in the analysis, a direct uretero-intestinal anastomosis was performed. In the early postoperative period, the failure of the anastomosiswith the development of urinary peritonitis was detected in 2 (2.7%) patients. Six months after the operation, unilateral anastomotic stricture was detected in2 patients (2.7%). Reflux of urine, without radiological signs of expansion of the renal cavity system and decreased renal function, was observed in 1 patientafter orthoptic plastic surgery of the bladder.Conclusion. Performing urinary-intestinal anastomoses without antireflux mechanisms does not lead to deterioration of long-term functional results and is as-sociated with a low frequency of strictures
