Primary obstructive megaureter in children; 10 years' experience from a tertiary care center

Abstract

Introduction: Primary obstructive megaureter (POM) is a congenital dilatation of the ureter due to an adynamic segment of vesicoureteric junction obstruction. Surgical intervention is needed if nuclear scan shows obstructive curve. We analyzed our data and outcome of conservative and surgical treatment in such cases at our tertiary care hospital. Materials and Methods: We evaluated all cases of POMs during the study period. Investigations included ultrasonography (USG), voiding cystourethrogram, diethylene pentacetic acid (DTPA) scan, and dimercaptosuccinyle acid scan. In antenatal cases, any pelvic dilatation ≥12 mm after 6 weeks were subjected to reonography. Patients with anterior-posterior pelvic diameter (APPD) ≥12 mm had to undergo DTPA scan to look for DRF and drainage. Follow-up USG was done in all cases of mild-to-moderate hydroureteronephrosis, with APPD 5% split function deterioration in the subsequent renal scan.
