[Acute retention of urine secondary to a congenital diverticulum of the bladder].

Bladder diverticula in children are mostly congenital, frequently associated with vesicoureteral reflux. Their positive diagnosis is based primarily on retrograde urethrocystography. One complication of this condition is acute urinary retention. We report the case of a 4-month-old infant who presented acute retention of urine secondary to bilateral congenital bladder diverticulum and review the literature on this subject.
