Objective      To describe the clinical efficacy of modified pneumoeystoscopic Glenn-Anderson ureter reimplantation for congenital malformation of vesicoureteral junction in children.       Methods      A total of 66 children (aged from 2 months to 14 years

median 4.5 years ) with congenital malformation of the vesicoureteral junction in our department from February 2006 to February 2013 were enrolled in this study. Among the patients

12 had vesicoureteral reflux (2 bilateral) and 54 had congenital vesicoureteral junction obstruction (4 bilateral). Two of the congenital vesicoureteral junction obstruction and 3 of the vesicoureteral reflux had recurrent urinary infection. All of the patients underwent modified Glenn-Anderson ureter reimplantation. A Foley catheter was indwelled in each patient but no bladder fistula was made. The stenting catheters were removed in 6 d after surgery. B-scan ultrasonography was used to follow the degree of the dilatation of ureter and hydronephrosis. Urinalysis was used to detect the urinary tract infection. Voiding cystourethrography was used in the patients with dilated ureters to show ureteral reflux.       Results      The procedure was completed in all but 1 patient

who was converted to open surgery because of gas leakage led by displacement of the port. The mean operation time was 125 min (70 to 200 min)

95 min (70 to 140 min) for unilateral cases and 136 min (110 to 200 min) for bilateral cases. All patients were free from complications such as surgical site infection or urinary tract infection. One case of bladder port side bleeding was observed. The ratio of no ureter dilation was 80%

89%

and 95% 3 months

6 months

and 12 months after surgery

respectively. No aggravated case was observed. Voiding cystourethrography showed I and Ⅲ degree urine reflux in 1 bilateral obstruction case and 1 unilateral cases 12 months after surgery with no urinary tract infection.       Conclusion      The modified pneumoeystoscopic Glenn-Anderson ureter reimplantation is a safe

effective option with few complications for congenital malformation of vesicoureteral junction in children.
