The vesical orifice may be contracted due to fibromuscular hyperplasia, to muscular hypertonia or to fibrosis. Each of these conditions may be either congenital or acquired, and may occur in either male or female children or adults. When the contracture is acquired it is usually a fibrous contracture, and is due to infection or is a sequela of operative procedures on the bladder neck.
