Congenital bladder diverticulum causing acute urinary retention in an infant.

Congenital bladder diverticula (CBD) are unusual but not rare in childhood. Report of acute urinary retention due to congenital bladder diverticula are rarely found in the literature. Here we report a case of congenital bladder diverticulum with acute urinary retention in a ten months old male infant. Urinary tract infection and urinary retention are the most frequent presentation forms. In this case CBD produce urinary obstruction as a result of compression of the urethra which causes urinary retention. Voiding cystourethrogram revealed a large bladder diverticulum. Bladder diverticulum should be a differential diagnosis in male children, presenting with urinary retention, fever and an abdominal mass. Ultrasonography, voiding cystourethrogram & cystoscopy confirm the diagnosis and diverticulectomy was successfully done for the child.
