Obstructed kidney secondary to a benign renal fibroepithelial polyp: A rare and interesting case

Abstract

Renal fibroepithelial polyp (FEP) is a very rare tumour and we describe a case causing acute ureteric obstruction. A 56 year old lady presented with presumed pyelonephritis and left hydronephrosis, without calculi. She was transferred to a tertiary hospital urology service where after an unsuccessful retrograde attempt at stent insertion, a nephrostomy was inserted. Subsequently, the patient underwent a ureteropyeloscopy and excision of a FEP arising from the renal pelvis. Renal FEP is a very rare cause of obstruction and was successfully managed endoscopically.
