OBJECTIVE

To explore the effectiveness of modified Politano-Leadbetter reimplantation for the treatment of congenital malformation of the vesicoureteral junction in children.

METHODS

A retrospective analysis was made on the clinical data of 53 patients with congenital malformation of the vesicoureteral junction treated with modified Politano-Leadbetter reimplantation between June 2000 and October 2014. Of 53 cases, there were 24 boys and 29 girls, aged from 8 months to 7 years (mean, 2.1 years); 23 had congenital vesicoureteral junction obstruction (14 left, 5 right, and 4 bilateral), and 30 had vesicoureteral reflux (12 unilateral, 18 bilateral), which were verified by voiding cystourethrography. The disease duration was from 1 month to 1 year (mean, 5 months).

RESULTS

All of the patients underwent modified Politano-Leadbetter reimplantation successfully. The mean operation time was 74 minutes (range, 65-85 minutes) for unilateral cases and 105 minutes (range, 98-130 minutes) for bilateral cases. There was no dysuria, infection of incision, or incision dehiscence after urinary catheter removal. The follow-up time was 6 months to 14 years (median, 28 months); all patients were free from complications of fistula, vesicoureteral reflux, vesicoureteral junction obstruction, or hypertension. The new ureteral orifices had good appearance at 1 month after operation. Urologic ultrasound showed that hydronephrosis relieved at 3 months after operation. Urinary tract infection rate was 13.2% (7/53) during 6 months after operation, which was cured by antibiotics. Voiding cystourethrography showed no vesicoureteral reflux in 32 cases at 6 months after operation.

CONCLUSION

The modified Politano-Leadbetter reimplantation simplifies he operation course, which has the longitudinal ureter after operation and is similar to physiological state. It is a safe and effective option for congenital malformation of vesicoureteral junction in children with few complications, especially for patients with unilateral megaloureter.
