摘要
OBJECTIVE:To evaluate the outcomes of children with vesicoureteral reflux (VUR) and obstructive megaureter (OM) utilizing various laparoscopic and robot-assisted approaches. MATERIALS AND METHODS:Retrospective review of all pediatric laparoscopic and robot-assisted cases for lower ureter pathology was performed between 2016-2022 in 13 academic centers worldwide. Five surgical approaches were assessed: LEUR, LVCUR, LDECUR, RALUR, and RADECUR. RESULTS:One thousand three hundred forty-three patients (490 boys and 853 girls) with a median age of 30 months (IQR 12-63) were treated at 13 centers. Nine hundred and eight patients (68%) underwent reimplantation due to VUR (unilateral in 818 and bilateral in 90 patients). Four hundred thirty-five (32%) had a surgery due to ureterovesical junction (UVJ) obstruction. Mean length of follow-up was 14 months (IQR 8-33). Median operative time was 202 minutes (IQR 142-220) in the robotic arm compared to 240 minutes (IQR 160-267) in the laparoscopic (P = .45). Intracorporeal excisional tapering was performed in 118 (8%) of the patients. Six patients in the OM group required additional surgery due to progressive obstruction. In the VUR group, 84% underwent voiding cystourethrography postoperatively. 5.6% showed residual reflux. Grade 1-2 Clavien-Dindo complications occurred in 10 patients (0.7%) and 6 (0.4%) in the laparoscopic and robotic arm, respectively. Grade 3 complications occurred in 17 (1.2%) and 8 (0.5%) in both arms, respectively. Surgical success was achieved in 96% of patients. CONCLUSION:Laparoscopic and robot-assisted laparoscopic approaches are simple, safe, and effective for treating all grades of VUR and OM. Robot-assisted approach is beneficial in terms of operative time, intracorporeal suturing, and lower complications rate.
