The Journal of Small Animal Practice (JSAP) has published a study which shows that if non-specific clinical signs are recognised correctly, ureter injuries during neutering can be treated successfully. 

For the study1, treatment and outcomes of ureter injuries due to ovariohysterectomy complications in cats and dogs was undertaken at the Royal Veterinary College. A retrospective case series of cats and dogs with ureteric injuries resulting from ovariohysterectomy was obtained from patient records at the Queen Mother Hospital for Animals. Fourteen female cats and five female dogs were included in the analysis. Descriptive statistics were used to report presenting clinical signs, clinical pathology, treatment and outcomes.

Professor Vicky Lipscomb, lead author of the paper, said “Presenting clinical signs of ureter injury following neutering in this study were non-specific, such as anorexia, vomiting and lethargy. Importantly, the clinical signs consistently developed immediately or shortly after surgery in the majority of animals. Therefore, the appearance of one or more clinical signs following neutering should raise suspicion of a neutering complication.

"The overall outcome for the 19 animals was excellent in 13 (68%), good in one (5%), fair in one (5%) and poor in four (22%). Ureteroneocystostomy (ureteral re-implantation) is preferred to ureteronephrectomy (removal of kidney and ureter) to preserve renal function and is usually a requirement for bilateral ureteric injuries but carries a high complication rate resulting in additional surgery, albeit often with an excellent final outcome.”

Nick Jeffery, editor of JSAP said: “Ovariohysterectomy is a common surgical procedure in cats and dogs, but the procedure carries a (low) risk of injury to one or both ureters due to the close proximity of the female reproductive tract and the ureters. This research highlights the need for vigilance regarding clinical signs following neutering but demonstrates that surgical treatment of ureteric injuries can have good patient outcome."
