RESEARCH COMMUNICATIONS OF THE 28th ECVIM-CA CONGRESS

The most frequent postoperative complications were transient worsening of the azotemia and severe polyuria. The most serious complications related to the SUB placement included a severe postoperative acute kidney injury that required 8 days of peritoneal dialysis for the case with communication between the pelvis and subcapsular space. The case of subcutaneous leakage was discharged the day after its surgical correction. Another case with bilateral obstruction was euthanized 4 days post surgery for persistent severe azotemia, hypotension and coagulopathy. One case of dysequilibrium syndrome was suspected secondary to a severe diuresis with rapid decrease of the azotemia. Fifteen of the 21 cats are still alive at the time of writing. All but 2 of their SUB device remain patent. The 2 cases with a non patent device did not present with recurrent hydronephrosis, leading to the suspicion of a patent ureter secondary to the ureterotomy performed at the time of SUB placement.
