Ectopic intra-scrotal supernumerary kidney

Abstract

Background: Supernumerary kidney is a rare congenital urologic malformation, of which approximately a hundred cases exist to date in the literature. This anomaly is an accessory kidney that possesses its own collecting system, blood supply and encapsulated parenchyma. Case presentation: We report the case of an eleven-month-old male infant presenting with multiple urinary tract infections and a dilated left ectopic ureter with grade II vesicoureteral reflux. The diagnosis of ectopic intra-scrotal supernumerary kidney was evoked following MRI, scrotal ultrasound and endoscopic exploration. Surgical resection by laparoscopy was subsequently performed and the postoperative course was uneventful. Conclusions: Supernumerary kidney is an extremely rare urologic malformation that requires multimodal preoperative imaging and management in a specialized pediatric surgical facility.
