Abstrakt:	Background: Urolithiasis prevalence varies globally between 1-20%, influenced by regional factors. Robotic pyelolithotomy (RPL) presents an interesting alternative to PCNL, considered the gold standard for symptomatic stones smaller than 20 mm, as it carries a risk of significant complications. However, studies on RPL are limited, especially in anatomically complex cases, where RPL proves to be particularly useful. The study aims to update and review outcomes of RPL in a high-volume robotic center. Methods: A retrospective analysis of 153 patients treated with RPL for staghorn kidney stones at a single center from February 2016 to December 2023 was conducted. Data including demographics, preoperative renal function, stone characteristics, operative and postoperative outcomes, and costs were collected. Stone-free rates (SFR) and complications were assessed at follow-up intervals up to 12 months post-surgery. Results: The study showed an initial 3-month stone-free rate (SFR) of 93.5%, which decreased to 83.5% at 12-months. This trend may reflect new stone formation rather than procedure failure. Sub-analysis revealed a significant difference in SFR between patients with pelvic and pyelocalyceal stones at each follow-up. Multivariate regression analysis identified in the pyelocalyceal group that higher BMI and larger stones were associated with higher failure rates at both 6 and 12 months. Conclusions: RPL is a safe and effective treatment for large renal stones, offering a high SFR and low complication rate. It is particularly beneficial in cases with complex anatomy or requiring concurrent renal procedures. However, patient selection is crucial, considering factors like stone location and size. Further research is needed to compare RPL with other treatment methods.
