Abstract
To determine the outcome in dogs undergoing urethral stent placement for management of urethral obstruction secondary to transitional cell carcinoma (TCC). Retrospective case series. 19 dogs with histopathologically confirmed TCC. Information regarding urethral stent placement and follow-up treatment was obtained from review of medical records. Quality of life assessment was performed with an owner questionnaire. Self-expanding nitinol stents were successfully placed in 17 of 19 dogs; stent placement was not possible in one dog, and another dog was euthanatized 2 days after stent placement, but before discharge from the hospital. Median survival time in 17 dogs following successful long-term stent placement was 78 days (range, 2 to 366 days). Complications following stent placement in 18 dogs included incontinence (n = 7), reobstruction from continued growth of urethral TCC (3), acute reobstruction shortly after the procedure (1), and stent migration (2). Of the 17 owners surveyed, 16 were satisfied with the outcome and would recommend urethral stent placement. The placement of self-expanding nitinol urethral stents was successful in alleviating TCC-induced urethral obstruction and providing good quality of life for most dogs.
