2015 ACVIM Forum Research Abstract Program

All three methods tested provided GFR measurements within the reported reference range for cats (1.5-3.5 mL/kg/min). However, only the recently developed Tk-GV method provided stable and precise results. This allowed detection of a difference between sequential studies suggesting superior utility for detecting interval changes in kidney function in healthy cats. Due to the heightened prevalence in the number of cats diagnosed with obstructive ureterolithiasis in recent years, surgery on the feline upper urinary tract has become more commonplace. Several techniques have been described for treatment of ureteral pathology in cats, including ureterotomy, neoureterocystostomy, ureteral stenting, and subcutaneous ureteral bypass. However, there is currently a paucity of veterinary literature documenting the success of these procedures. The objective of our study was to report on the perioperative complications and mortality rate in cats undergoing ureterotomy, neoureterocystostomy, and surgical ureteral stent placement. We also describe the long-term success of intervention, both with regards to the prevalence of persistent clinical signs of urinary tract dysfunction and the prevalence of urinary tract re-obstruction.
