Results of laparoscopic extravesical antireflux operation in vesicoureteral reflux in children

Abstract

The objective was to improve the results of surgical treatment of vesicoureteral reflux in children, using laparoscopic access. The prospective study was performed in 111 children (137 ureters) with the primary III–IV grade vesicoureteral reflux. The mean age was 34.7 months. The modified laparoscopic antireflux technique was performed on 73 children (91 ureters). We compared the perioperative complications and the medium-term outcome with a group of 38 children (46 ureters) who underwent classical laparoscopic extravesical reimplantation.3 In the modified group, the mean surgery time was 109.8 ± 31.5 minutes for unilateral cases and 176.5 ± 47.6 minutes for bilateral cases; in the classical group, it was 118.6 ± 34.3 and 209.5 ± 51.2 minutes respectively (p > 0.05). Postoperative vesicoureteral reflux had 2 (2.7 %) patients in the main group and 8 (21.1 %) children in the control group (p  =  0.002). There was no ureteral obstruction in the both groups. The success rate for ureters was 97.8 % with modified technique versus 82.6 % after classical laparoscopic reimplantation (p = 0.003). Laparoscopic extravesical ureteral reimplantation is a safe and effective surgical procedure. The modified technique may improve the surgical treatment results.
