Outcomes were compared between device types.<\/jats:p>\n<jats:p><jats:bold>RESULTS<\/jats:bold> Median durations of surgery and hospitalization were significantly longer in the stent versus UB group. Perioperative mortality rate was 18% (5\/27) in the stent group and 13% (3\/23) in the UB group. Median survival time was shorter in the stent versus UB group. Stent placement was associated with a greater risk of lower urinary tract\u2013related signs, such as hematuria (52% [14\/27]) and pollakiuria or stranguria (48% [13\/27]). The risk of device occlusion was also greater in the stent (26% [7\/27]) versus UB (4% [1\/23]) group. The percentage of cats requiring additional procedures to treat complications was greater in the stent (44%; complications included uroabdomen, stent occlusion, and refractory cystitis) versus UB (9%; complications included UB occlusion and urethral obstruction) group.<\/jats:p>\n<jats:p><jats:bold>CONCLUSIONS AND CLINICAL RELEVANCE<\/jats:bold> Although the benefits of stent placement in the treatment of ureteral obstruction in cats have been established, results suggested that cats treated with UB devices had a lower risk of complications and a longer survival time than those treated with double-pigtail ureteral
