BACKGROUND There are many reports on the application of minimally invasive technology in the correction of children's VUJO, but there is no report on the treatment of children's VUJO by the TU-LESS Lich-Gregoir method. We aimed to comparatively analyze the therapeutic outcomes of transvesicoscopic ureteral reimplantation Cohen procedure (TUR-C) and TU-LESS surgery Lich-Gregoir procedure (TU-LESS-LG) in pediatric VUJO. METHODS The data of 49 children with VUJO admitted from January 2016 to January 2020 were retrospectively analyzed. Based on different surgical methods, they were divided into the TUR-C group (23 cases) and the TU-LESS-LG group (26 cases). The demographic characteristics, perioperative characteristics, postoperative complications, the recovery of renal function, and the improvement of hydronephrosis were compared between the two groups. RESULTS There were no statistical differences in demographic characteristics and preoperative data between the two groups. The TU-LESS-LG group was superior to the TUR-C in terms of average operation time and postoperative hospital stay. There was no statistical difference between the two groups in terms of postoperative complications, postoperative recovery of renal function, and improvement of hydronephrosis. CONCLUSION The two surgical methods can achieve a similar curative effect in the treatment of VUJO. The TU-LESS-LG has more advantages in operation time, postoperative hospital stays, the wider age selection range of cases, megaureter tapering, and cosmetic incision, but the operation is more difficult.
