Three Cases of Bladder Duplication

Abstract Three cases of bladder duplication are described. Duplication of the bladder is a rare anomaly. In bladder duplication there may be a bilateral complete duplication of the bladder and urethra or an incomplete duplication, in which case there is a single urethra. Further, the bladder may be divided in two parts by a complete or incomplete sagittal septum or a complete or incomplete frontal septum. Complete bilateral duplication of the bladder and urethra is part of a rare and striking anomaly that involves the entire caudal end of the body. Diagnosis demands exploration of all orifices to determine the anatomic relationship and the functional possibilities. Treatment for duplication of the bladder may be complex because of the many associated anomalies and is usually limited to procedures for maintaining normal function. Initial treatment is directed at assuring that there is no obstruction or infection.
