Congenital Bladder Diverticula as a Cause of Bladder Outlet Obstruction in Children

Introduction

Bladder diverticulum develops as herniation of bladder mucosa between defects of bladder smooth muscle fibers. Bladder diverticula can be congenital or acquired. The majority of bladder diverticula are asymptomatic and are discovered accidentally. However, some may cause problems such as repeated urinary tract infection or, rarely, outflow obstruction, particularly the congenital variety. Obstructing diverticula can lead to loss of kidney function. Awareness of this condition helps in early diagnosis and avoid kidney damage.

Here we review our experience over the last 13 years with urinary bladder diverticula which had enlarged enough to cause obstruction at the bladder neck level.
