Abstract :Objective: The aim of this study was to compare the efficacy and safety of lithotripters used in supine mini percutaneous nephrolithotomy. Material and Methods: Medical record of patients who underwent mini percutaneous nephrolithotomy in supine position between January 2023 and June 2024 due to kidney stone larger than 2 cm were evaluated. Thirty-nine patients were operated with Ho:YAG laser lithotripter (LL) and 54 patients were operated with pneumatic lithotripter (PL). Results of patients’ demographics, stone size, stone density, operation time, stone-free rate (SFR), complications were compared. Results: Mean age was 49.56±13.02 in LL group and 50.20±14.24 in PL group (p=0.825). Mean stone size was 3184±2117 mm³ in LL group and 4117±2975 mm³ in PL group and the results were similar between groups (p=0.097). Operation time was significantly higher in LL group than PL group (99.8±24.7 min, 85.7±28.1 min, respectively). SFR at postoperative 3rd month was similar between groups (92% in LL, 87% in PL) (p=0.512). Hemoglobin decrease rate (1.5±1.1 g/dL (IQR 1.5 g/dL) (LL) vs. 1.6±1.0 g/dL (IQR 1.6 g/dL) (PL), p=0.513) and overall complication rates (20% vs. 18%, p=0.897, respectively) were similar in the groups. Conclusion: Both lithotripters can be preferred effectively in supine percutaneous lithotomy. Ballistic lithotripters are still a safe and effective option for mini-PNL with the advantage of reduced operation time.
