Endoscopic trigonoplasty in pediatric patients with primary vesicoureteral reflux: preliminary report.

Abstract

We investigated the preliminary surgical results of endoscopic trigonoplasty in pediatric patients with primary vesicoureteral reflux. We performed endoscopic trigonoplasty in 6 pediatric patients (11 refluxing ureters). Reflux was grade II in 4 reno-ureteral units, grade III in 5, grade IV in 1 and grade V in 1 (international classification). Surgery was done using laparoscopic and endoscopic instruments. Vesicoureteral reflux disappeared 3 to 12 months postoperatively. Analgesics were administered postoperatively to 4 patients for 24 hours and to 2 for 48 hours. No bladder irritability or postoperative upper urinary tract dilatation was observed in the early postoperative period. Minimally invasive endoscopic trigonoplasty can be an effective surgical procedure for pediatric patients with vesicoureteral reflux.
