Bladder Outlet Obstruction Secondary to a Brunn's Cyst

Gwen M Grimsby et al. Curr Urol. 2012 May.

Abstract

Introduction: Bladder outlet obstruction in younger men is often secondary to urethral stricture disease. In the older population it is often a result of benign prostatic hypertrophy.

Materials and methods: We describe the diagnosis, treatment, and outcome of a rare case of a Brunn's cyst causing bladder outlet obstruction in a 43-year-old male who was evaluated for obstructive urinary complaints.

Results: Ultrasound and cystoscopy revealed a cystic lesion at the bladder neck. Transurethral unroofing of the cyst resulted in resolution of the obstructive symptoms and resumption of normal voiding. Final pathology revealed a cystic structure with predominately denuded urothelium with multiple submucosal cystically dilated von Brunn's nests, most consistent with a Brunn's cyst. A search of the literate reveals only one similar case.

Conclusions: We present the rare case of a Brunn's cyst causing bladder outlet obstruction in a young man.

Keywords: Brunn's cyst; Obstruction; Prostate.
