Dérivation pyélo-vésicale extra-urétérale sur un cas de rupture urétérale chez un chat

This report describes a cat that was presented with abdominal distension and pain with mild hyperthermia two weeks after the successful treatment of a traumatic diaphragmatic hernia. Further diagnostic investigations confirmed mild retroperitoneal and peritoneal effusion associated with mild azotaemia. Biochemical analysis of the abdominal fluid was compatible with uroperitoneum. An intravenous urography revealed an unilateral left ureteral rupture. Surgical treatment was elected. Conventional techniques such as ureteronephrectomy or ureteral anastomosis were judged inappropriate to treat this cat either in order to preserve his mild impaired renal function or given the extent and proximal location of the rupture, respectively. New minimally invasive techniques were favored. A ureteral stent could not be placed because of a major ureteral stricture. The cat was finally managed surgically by a subcutaneous ureteral by-pass (SUB) system. The immediate and long-term (11 months) clinical and biological outcome was good with a normal renal function at the last recheck.
