Prenatal hydronephrosis revealing a bladder diverticulum

Luiz G Freitas Filho et al. Urol Case Rep. .

Abstract

Bladder diverticula can be either congenital or acquired. They are the formation of a urothelial hernia through the muscle wall fibers of the bladder. Congenital bladder diverticula are rare and there are no previous reports showing them to have been found through an antenatal ultrasound exam revealing the presence of hydronephrosis. Here we describe the case of a large congenital bladder diverticulum revealed through an antenatal hydronephrosis diagnosis and whose proximity to the ureter led to its removal and a ureteral reimplantation.

Keywords: Congenital bladder diverticula; Hydronephrosis; Urinary tract infection.
