Abstract

Objective: The objective of this work is to evaluate the safety and short-term outcomes of laparoscopic dismembered pyeloplasty (LDP) for ureteropelvic junction obstruction (UPJO) in children, based on a single-surgeon experience using a transabdominal suspension technique.

Methods: We retrospectively analyzed children with UPJO between January 2023 and October 2024 who underwent transperitoneal LDP with a transabdominal suspension maneuver performed by a single surgeon. The diagnosis was confirmed by ultrasonography and magnetic resonance urography. The outcomes were operative time, complications, hospital stay, and postoperative hydronephrosis reduction, assessed by ultrasonography at least 3 months after the operation.

Results: A total of 60 children with a mean age of 58.5 months (range: 6-168 months) underwent surgery during the study period; of these, 47 were boys. The mean operative time was 140 min (range: 120-200 min). No open conversions or major complications occurred. The mean hospital stay was 3.5 days. The median pelvic diameter decreased from 35.6 mm (range: 25-50 mm) preoperatively to 13.5 mm (range: 8-22 mm) postoperatively (p < 0.05). All patients were free from symptoms with reduced hydronephrosis during the follow-up period.

Conclusions: Transperitoneal laparoscopic dismembered pyeloplasty is a safe and effective option in the treatment of UPJO, and a transabdominal suspension technique may facilitate the procedure.

腹腔镜下肢解肾盂成形术治疗儿童肾盂输尿管连接处梗阻：一名外科医生的经验。

目的：本研究的目的是基于单外科医生使用经腹悬吊技术的经验，评估腹腔镜解离性肾盂成形术（LDP）治疗儿童输尿管肾盂连接处梗阻（UPJO）的安全性和短期效果。方法：我们回顾性分析了2023年1月至2024年10月期间由一名外科医生进行经腹膜LDP和经腹膜悬吊术的UPJO患儿。经超声及磁共振尿路造影证实。结果是手术时间，并发症，住院时间，术后肾积水减少，术后至少3个月超声评估。结果：研究期间共有60例儿童接受手术治疗，平均年龄58.5个月（范围：6-168个月）；其中47人是男孩。平均手术时间140 min （120 ~ 200 min）。无开放性转换或重大并发症发生。平均住院时间为3.5天。盆腔中径由术前35.6 mm（范围：25-50 mm）降至术后13.5 mm（范围：8-22 mm）。(p)结论：经腹腔腹腔镜分型肾盂成形术是治疗UPJO安全有效的选择，经腹悬吊技术可促进手术。
