OBJECTIVE: To determine the outcome of minimally invasive ureteral stent placement for @entity235 with @entity1695 . DESIGN-Retrospective case series. ANIMALS: 12 @entity235 (15 ureters) with @entity1695 secondary to a trigonal @entity189 . PROCEDURES: In all @entity1 , indwelling, double-pigtail ureteral stents were placed by means of percutaneous antegrade needle and guide wire access under ultrasound and fluoroscopic guidance. RESULTS: Stents were successfully placed in all @entity1 . In 11 of 12 @entity1 , percutaneous antegrade access was accomplished. One @entity1 required access via laparotomy because percutaneous access could not be achieved. The median survival time from the date of diagnosis was 285 days (range, 10 to 1,571 days), with a median survival time of 57 days (range, 7 to 337 days) from the date of stent placement. Three complications occurred in 1 @entity1 . Seven @entity1 required concurrent urethral stent placement for relief of @entity11044 . All animals were discharged from the hospital (median hospitalization time after stent placement, 18 hours [range, 4 hours to 7 days]) with an indwelling, double-pigtail ureteral stent (3 bilateral and 9 unilateral) in place. All stents evaluated 0.25 to 11 months after placement were considered patent. CONCLUSIONS AND CLINICAL RELEVANCE: Findings suggested that ureteral stent placement was safe, effective, and well tolerated in @entity1 with @entity1695 . Stents could be reliably placed in a minimally invasive manner and remain patent long-term. Ureteral stent placement should be considered as early as possible in @entity1 with @entity5 , prior to the development of permanent @entity8 .
