Double J ureteral stenting in a cat with ureteral obstruction

The feline ureter is susceptible to obstruction caused by various factors, including lithiasis, stenosis, neoplasia and retrocaval ureter. However, lithiasis stands as the primary cause, followed by ureteral strictures. Clinical manifestations in affected cats are often nonspecific, contingent upon the degree and laterality of obstruction, with azotaemia being a prominent consequence. This study aims to document a surgical intervention employing a double J catheter in a cat presenting with ureteral obstruction. A 12‐year‐old, male cat presented with anuria, sporadic vomiting, weight loss and anorexia. Laboratory exams revealed severe azotaemia, corroborated by ultrasonography displaying a pseudocyst and signs indicative of ureteral obstruction. Consequently, hospitalisation ensued with exploratory laparotomy surgery. During the procedure, a left nephrectomy became necessary. Utilisation of the double J catheter in the right ureter was pivotal, alongside right ureteral transposition and catheter insertion for peritoneal dialysis. After surgery, peritoneal dialysis commenced promptly. A significant reduction in azotaemia was observed by the end of hospitalisation, along with normal urination and spontaneous feeding. The efficacy of employing the double J ureteral catheter was evident in restoring urinary flow and expediting the patient's recovery period, as evidenced by the data presented.
