Surgical treatment of primary obstructive megaureter is generally recommended when ureteral dilatation is likely to contribute to symptoms such as pyelonephritis or calculi. The authors’ objective for this study was to present the surgical results performing ureteral reimplantation, combined with modified Lich-Gregoir antireflux procedure (using anchoring stitch) over a 10 year period. The average operative time for ureteral reimplantation was 259.64 minutes. The authors’ success rate was 92% and all patients had no postoperative ureteral obstruction from intussusception of reimplanted ureter. Follow-up postoperative renal sonography at 22 weeks showed a decrease in hydronephrosis in 92%. The authors concluded that the surgical results were comparable with surgical results of other techniques and an anchoring stitch should be considered to prevent postoperative ureteral obstruction from ureteral intussusception.
