Endourological management in a newborn with incomplete bladder duplication.

We report an unusual case of a newborn with incomplete bladder duplication and a complete sagittal septum. This malformation was associated with dysplasia of the right kidney, right cryptorchidism, single urethra, and no other genital or gastrointestinal anomalies. At birth, we found severe ureterohydronephrosis in a solitary left kidney caused by the collapse of the left bladder when the right bladder was filled. We performed a neonatal puncture of the bladder septum. At 3 months of life, the patient underwent complete resection of the septum by cystoscopy with monopolar electrocautery. There are no previously reported cases of a newborn with obstructed uropathy. This is the first reported case of incomplete bladder duplication with endourological management.
