Abstract
Objective
To assess the clinical efficacy of laparoscopic Lich–Gregoir (LLG) and transvesicoscopic Cohen reimplantation (TCR) in the treatment of vesicoureteral junction obstruction (VUJO) and vesicoureteral reflux (VUR).
Methods
This study retrospectively analyzed the clinical data of 66 pediatric patients with VUJO and VUR. They were classified into two groups, undergoing either the laparoscopic Lich–Gregoir operation (LLGO) (n = 35) or transvesicoscopic Cohen reimplantation operation (TCRO) (n = 31). The surgeries were performed between April 2018 and September 2022 at the First Affiliated Hospital of Guangxi Medical University, China. General characteristics, preoperative attributes, postoperative complications, renal function recovery, and improvement of hydronephrosis were compared between the two groups.
Results
All surgical procedures were successful with no requirement for reoperation. Both groups were comparable with respect to gender, affected side, weight, and postoperative complications. Nonetheless, the LLGO group contained a greater number of children younger than 12 months. The LLGO group demonstrated superiority over the TCRO group regarding the duration of the operation, intraoperative blood loss, and length of postoperative hospital stay. In contrast, postoperative complications, recovery of renal function, and hydronephrosis improvement did not exhibit statistically significant differences between the two groups.
Conclusion
Both LLGO and TCRO were demonstrated to be precise, safe, and reliable surgical methods for treating pediatric VUJO and VUR. LLGO ureteral reimplantation offers particular advantages in selecting cases and appears more suitable for children younger than 12 months who have a small bladder capacity.
