Collateral bladder duplication with exstrophy of one moiety in a female infant

Abstract 

Complete bladder duplication with exstrophy of one moiety is an extremely rare condition. We report an unusual case of complete bladder duplication with exstrophy of one moiety, in which each bladder received one ureter and the internal bladder drained into a urogenital sinus. The patient was treated by combining the two bladder halves and using the bladder neck of the internal bladder, with excellent cosmetic result. This case underscores the importance of ultrasonography and computed tomography to detect the anatomy of the patient with exstrophy in whom the ureteric orifices cannot be clearly identified on both sides of the trigone.
