URETERAL REPLACEMENT TECHNIQUES

摘要

Ileal-ureteral substitution has been performed in people with generally favorable results.Surgery of the feline ureter presents a variety of challenges to the veterinary surgeon.Ileal-ureteral substitution can be performed successfully in the catThe feline ureter can provide many challenges to veterinary surgeons. Current options for a stenotic feline ureter include resection and anastomosis, division of the ureter proximal to the obstruction and reimplantation into the bladder (ureteroneocystostomy), nephrectomy, and anastomosis into the contralateral ureter to provide diversion of the urine flow. The small diameter and limited length of the ureters of cats make it difficult to perform resection and anastomosis, even with high-powered magnification. Postoperative complications, including stricture and urine leakage, complicate recovery and reduce the chances for a successful outcome. Because of a lack of ureter length, strictures in the mid to proximal portion of the ureter may eliminate theability to perform a ureterneocystostomy, even with cranial mobilization of the urinary bladder and caudal mobilization of the kidney. When possible, stenting of the ureter can be performed successfully to relieve ureteral obstruction.
