Primary obstructive megaureter: the role of high pressure balloon dilation.

Background And Purpose: There is a growing interest in minimally invasive treatment of primary obstructive megaureter (POM) in children. The absence of long-term follow-up data, however, makes it difficult to establish the indication for an endoscopic approach. The aim of our study is to determine the long-term efficacy of endourologic high-pressure balloon dilation of the vesicoureteral junction (VUJ) in children with POM that necessitates surgical treatment.

Is intraoperative surgeon's opinion an accurate tool to assess the outcome of endoscopic treatment for vesicoureteral reflux?

Objective: Our experience in the endoscopic treatment of vesicoureteral reflux (VUR) has significantly increased during the last decade. To help develop diagnostic tests to check the success of this procedure, we evaluated the accuracy of surgeons' intraoperative observations as a predictor of treatment results.

Method: We performed a prospective study of patients with VUR who were endoscopically treated during 1 year (106 renal units).

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.
