Hour-glass bladder was detected by X-ray investigation in a newborn female infant with delayed postpartum micturition. No signs of difficulty in micturition or urinary tract infection were subsequently detected. Control X-ray investigation at the age of 5 1/2 months showed a completely normal-shaped urinary bladder. This finding contrasts with the general opinion that hour-glass bladder is caused by a congenital malformation.
