Ureteral distal ends combined and inserted into the ileum: a novel anastomotic technique for urinary diversion

This study aimed to introduce a novel method for ureteroileal anastomosis, explore its clinical effectiveness, observe the incidence of postoperative anastomotic stricture, and compare the postoperative complications with those of other types of ureteroileal anastomosis reported in the literature. Both ureters were first anastomosed at their distal ends and then inserted into the proximal end of the ileal loop. A postoperative follow-up analysis was performed to evaluate major complication indicators, including anastomotic stricture, anastomotic leak, and hydroureteronephrosis. We successfully performed ureteral distal ends anastomosis combined with end-to-end insertion into the ileum for 143 patients. The mean postoperative follow-up lasted 37 months (range: 10-68 months). There was no occurrence of an anastomotic leak. The incidence of anastomotic stricture combined with hydronephrosis, ileal conduit stones, urinary tract infection, and renal dysfunction were 2.1%, 0.7%, 2.1%, and 4.2%, respectively. Ureteral distal ends combined and inserted into the ileum were simple to perform and helped achieve precise anastomosis with fewer postoperative complications.
