[Endoprosthesis of the ureter].
A stent made of titanium nikelide monothread was used in the treatment of 37-63 year old male patients with recurrent and long strictures of the ureters. A metal stent was used in 3 patients with recurrent and long structures of the ureter. A long pyeloureteral stricture developed in two patients with allotransplanted kidney after several operations. The stricture in one patient was caused by a failed resection of the pyeloureteral segment and subsequent attempts of endoscopic correction of the upper urinary tract. Metal stents were used in all the cases. No serious postoperative complications were observed. The operations were effective. No lethal outcomes occurred. Follow-up for 6 to 13 months stated normalization of urodynamics and function of the affected kidney. Thus, a metal stent in some cases of recurrent and long ureteral strictures reestablishes passability of the upper urinary tract and improves quality of life.
