Use of indwelling, double-pigtail stents to treat malignant ureteral obstruction in dogs

A. C. Berent, C. Weisse, M. W. Beal, D. C. Brown, K. Todd, D. Bagley

INDWELLING ureteral stents are routinely used in human medicine to maintain urine flow from the renal pelvis into the urinary bladder. This retrospective study determined the outcome of minimally invasive ureteral stent placement in dogs with ureteral obstructions.

Medical records of dogs examined at two veterinary hospitals in the USA were reviewed between 2006 and 2009. Dogs were selected if percutaneous placement of a double-pigtail ureteral stent had been attempted to treat ureteral obstruction secondary to a trigonal urothelial carcinoma. In all animals, stents was placed using antegrade needle and guide-wire access under ultrasound and fluoroscopic guidance. Information analysed included signalment, medical history, diagnostic imaging results, procedure time, any associated complications, and follow-up data.

A total of 12 dogs were included in the study, with stents being placed successfully in all animals (three bilateral and nine unilateral). Percutaneous antegrade access was accomplished in 11 of 12 cases; in one case, access via laparotomy was required. The median survival time from the date of diagnosis was 285 days (range 10 to 1571 days), with a median survival time of 57 days (range seven to 337 days) from the date of stent placement. One dog …
