Case of Diagnosis of Congenital Hydronephrosis with Perirenal Pseudocyst in a Cat

Abstract

A 4-month-old female American Curl kitten was evaluated for right renomegaly. A diagnostic imaging series revealed structural abnormalities in the right kidney, indicating severe hydronephrosis or a cystic kidney. During an exploratory laparotomy, a retrocaval ureter was noted, but no calculi, masses or any other causes of ureteral obstruction were found. A nephrectomy of the enlarged right kidney was performed. The histopathological diagnosis was right hydronephrosis with perirenal pseudocysts.
