A rare cause of acute urinary retention in a male infant.

Acute urinary retention is an uncommon entity in childhood, and is associated with a variety of causes. Congenital bladder diverticulae are a rare cause of this condition, and occur almost exclusively in boys. True congenital diverticulae are most often solitary. Acute urinary retention is an extremely rare complication of congenital bladder diverticulae. Voiding cystourethrography is considered the most reliable method for detection. We report a case of a 3-month-old male infant who was presented with several episodes of acute urinary retention caused by bilateral congenital bladder diverticulae. Clinical and radiological evaluation and surgical correction are discussed.
