[Pyeloureteral junction syndrome. Associated vesicoureteral reflux]

Abstract

We reviewed our series comprised of 106 children that had undergone surgery for congenital hydronephrosis from ureteropelvic junction obstruction. Following our protocol, all patients were evaluated by serial micturition cystourethrography. The only anomaly that had been detected was vesicoureteral reflux in 11.32% of the cases. This incidence is reduced to 8.25% if only the renoureteral systems with both congenital anomalies are considered. This finding is not statistically significant (p less than 0.05) relative to patient age, sex or clinical symptoms. The results of the present study show that children with ureteropelvic junction obstruction are not at risk of developing vesicoureteral reflux. Thus, routine serial micturition cystourethrography appears to be unwarranted.
