Abstract

Objective: This study aimed to evaluate the outcomes of retrograde intrarenal surgery (RIRS) for the treatment of kidney stones, focusing on patient characteristics, stone-free rates, and perioperative management. Materials and Methods: This study is a combined retrospective and prospective, descriptive case series of 71 patients treated with flexible ureteroscopy for kidney stones at the Central Military Hospital 108 from August 2022 to June 2024. Patient data, including demographic information, clinical presentations, stone characteristics, and surgical outcomes, were collected and analyzed. Results: The study included 71 patients: 48 males (67.6%) and 23 females (32.4%), with a mean age of 50.4 ± 10.2 years (range 28-76). Mean stone size was 16.9 ± 4.6 mm (range 8-25 mm). Hydronephrosis was graded as Grade 1 in 42 patients (59.2%), Grade 2 in 27 (38%), and Grade 3 in 2 (2.8%). Stone-free rates immediately postoperatively, at 1 month, and at 3 months were 81.7%, 83.1%, and 84.5%, respectively. Mean operative time was 37.9 ± 16 minutes (range 13-81 minutes). Mean hospital stay was 1.6 ± 0.8 days (range 1-4 days), shorter than with other surgical methods. The overall complication rate was 12.7%, with all complications being Clavien-Dindo Grade I or II. Conclusions: The results of this study suggest that modular flexible ureteroscopy and Holmium laser lithotripsy can be considered a primary treatment option for renal and proximal ureteral calculi ≤25 mm in size, due to its high success rate, short hospital stay, and acceptable complication rate. Further studies are warranted to optimize treatment protocols and improve long-term stone-free rates.
