Plain-English summary
A group of 95 cats underwent a procedure called subcutaneous ureteral bypass to treat severe urinary issues. Unfortunately, 10 of these cats did not survive the hospital stay, and 40 more died or were euthanized after going home, with a median survival time of about 530 days. Many cats experienced complications, including urinary tract infections, but most were manageable. Cats with lower kidney function at the start had a shorter survival time compared to those with better kidney health. Overall, the procedure can lead to a median survival of over 2 years for many cats.

Abstract
OBJECTIVES: To report the complications and factors affecting outcome for cats following placement of a subcutaneous ureteral bypass (SUB™). MATERIALS AND METHODS: In this retrospective study, complications, the presence of a urinary tract infection and survival time were recorded following subctutaneous ureteral bypass placement. Factors affecting survival time were assessed using a Kaplan Meier curve and log rank test. RESULTS: Ninety-five cats had 130 subcutaneous ureteral bypasses placed. Ten cats did not survive to discharge. Forty cats died or were euthanised after discharge (42%); the median survival time of these cats was 530 days (range 7 to 1915). Minor complications occurred in 18 cats (19%) and major complications occurred in 46 cats (48%), the majority of which were after hospital discharge. Twenty-seven cats were diagnosed with a urinary tract infection (UTI) post-operatively. A significant association between long-term survival and creatinine at presentation was identified. The median survival time for cats presenting with creatinine concentration ≥440 μmol/L (International Renal Interest Society stage acute kidney injury (AKI) 4 and 5) was 530 days (95% CI 273-787 days), compared to a median survival time of 949 days (95% CI 655-1243 days; Log Rank P=0.024) for those cats presenting with creatinine <440 μmol/L (International Renal Interest Society stage AKI 1-3). CLINICAL SIGNIFICANCE: In this population of cats, subcutaneous ureteral bypass placement was associated with an approximately 10% in-hospital mortality and a high complication rate. Most complications were manageable, resulting in an overall median survival time of over 2 years.
