Background: Pediatric urolithiasis has become increasingly prevalent worldwide, necessitating safe and effective treatment options that ensure complete stone clearance while preserving renal function. Objective: This study aimed to compare the efficacy and safety of laser lithotripsy versus SWL in the management of pediatric urinary stones.
Methodology: This comparative cross-sectional study was conducted at Type-D hospital Latamber Karak from June 2023 to June 2024. A total of 143 pediatric patients aged 2–16 years diagnosed with urolithiasis were included and divided into two groups: Group A (laser lithotripsy, n = 72) and Group B (SWL, n = 71). Data regarding demographics, stone characteristics, treatment outcomes, complications, and hospital stay were recorded.
Results: The mean age of participants was 9.0 ± 3.5 years, with a male predominance (60.8%). Both groups were comparable in baseline characteristics. The stone-free rate after one session was significantly higher in the laser group (90.3%) compared to the SWL group (71.8%) (p = 0.006), which further increased to 96.0% and 85.9%, respectively, after two sessions (p = 0.04). Patients in the laser group required fewer treatment sessions (1.2 ± 0.4 vs. 1.6 ± 0.5; p < 0.001) and had shorter hospital stays (1.9 ± 0.7 vs. 2.6 ± 0.8 days; p < 0.001). Minor complications such as fever and hematuria occurred in both groups, with no significant difference (p > 0.05) and no major complications reported.
Conclusion: It is concluded that both laser lithotripsy and shock wave lithotripsy are effective and safe in managing pediatric urolithiasis; however, laser lithotripsy offers superior efficacy with higher stone-free rates, fewer sessions, and shorter hospital stays.
