Influencing factors of laparoscopic pelvic urethroplasty in the treatment of children with hydronephrosis

OBJECTIVE: The purpose of this study was to evaluate the clinical efficacy of lap-aroscopic pyeloureteroplasty in the treatment of children suffering from hydronephrosis.PATIENTS AND METHODS: Our pediatric de-partment received 160 children with hydrone-phrosis from January 2019 through December 2021. These children were randomly assigned to either the control group or the study group with 80 cases in each group. The control group under-went traditional open pyeloureteroplasty, while the study group underwent laparoscopic pyelo-ureteroplasty. After assessing the results of both groups, the clinical outcomes were compared.RESULTS: The study group had a significant-ly shorter operating time, lower intraoperative bleeding rate, and shorter hospital stay than the control group. On the first day after the opera-tion, there was no significant difference between the control and study groups, and on the sev-enth day after the operation, the study group's OPS was significantly lower than that of the con-trol group. A significant difference was observed after treatment between the study group and the control group in terms of the anteroposterior di-ameter of the renal pelvis. Both groups' GFR in-creased significantly with time, and the GFR of the study group was significantly greater than that of the control group at 3 months after the op-eration, but there was no significant difference at 6 months after the operation. Postoperative ad-verse effects did not differ significantly between the two groups. CONCLUSIONS: Pediatric laparoscopic py-eloureteroplasty can reduce intraoperative bleeding, shorten operation time and hospital stay, alleviate postoperative pain, and promote the recovery of postoperative renal morpholo-gy and function in children with hydronephrosis, which merits further discussion.
