Transperitoneal laparoscopic pyeloplasty for the treatment of ureteropelvic junction obstruction in children: Experience from Hue Central Hospital

Objective: This study aims to evaluate the safety and effectiveness of transperitoneal laparoscopic pyeloplasty in treating ureteropelvic junction obstruction (UPJO) in children. Methods: This was a prospective study, including pediatric patients aged ≤16 years who underwent transperitoneal laparoscopic pyeloplasty from June 2021 to June 2024. Recorded parameters included operation time, blood loss, intraoperative and postoperative complications, hospital stay, and surgical outcomes. Success was defined as improvement in symptoms and/or resolution of obstruction on postoperative renal scintigraphy. Results: We performed transperitoneal laparoscopic pyeloplasty using the Anderson-Hynes technique on 30 patients. The mean age was 30.2 ± 8.6 months, with male-to-female ratio of 2.75. The average operative time was 122.38 ± 21.11 minutes, with minimal blood loss. The average postoperative hospital stay was 4.76 ± 1.34 days. One patient experienced a postoperative fluid collection. The average follow-up duration was 14.7 ± 4.2 months (ranging from 8–18 months). The overall success rate was 100%. Conclusion: Transperitoneal laparoscopic pyeloplasty is a safe, effective, and minimally invasive surgical method for children with ureteropelvic junction obstruction. This technique provides favorable long-term outcomes with a low complication rate.
