| Summary: | Background: Pediatric urolithiasis, while less common than in adults, is increasing in incidence. However, current guidelines on the optimal management of this condition vary. Technological advances have led to improvements in the quality and size of ureteroscopes, thus enabling their use in children. Despite this, there remains some hesitancy about using ureteroscopic lithotripsy in the pediatric population, particularly in cases of large stones ⩾10 mm. Objectives: In this study, our aim was to evaluate the efficacy and safety of ureteroscopy and laser stone fragmentation (URSL) for managing pediatric patients with a cumulative stone burden of ⩾10 mm in our tertiary referral center. Methods: A dataset was collected of pediatric renal tract stone patients treated at a single tertiary urological center between June 2010 and May 2024 (15 years). Pediatric patients undergoing URSL procedures for a minimum cumulative stone burden ⩾10 mm were included. A retrospective analysis of the dataset was conducted. The primary outcomes measured were stone-free rates (SFR), complications classified according to the Clavien-Dindo classification, and hospital length of stay. Results: A total of 61 pediatric patients with a mean age of 10 years (range: 2.3–16) underwent 83 URSL procedures in a tertiary endourology pediatric center over a 15-year period (2010–2024). The median initial stone burden was 17 mm (IQR: 12.5–24 mm), acquired from preoperative ultrasonography (USS). Results showed a first-pass SFR of 63.9% and a cumulative SFR of 93.4% (on USS) following one or multiple URSL procedures (1.4 procedures/patient). Immediate postoperative complications were minimal, with 6% experiencing complications classified as Clavien-Dindo I or II. The average hospital length of stay was 1.4 days. Conclusion: The findings in this study support that URSL is effective in treating pediatric urolithiasis, even for larger stone burdens. Further research is needed to standardize guidelines and optimize management strategies in this population. |
