Aim: The indications for retrograde intrarenal surgery (RIRS) have greatly increased, however, there is still no consensus on the use of spinal anesthesia (SA) during this procedure. The aim of this study was to evaluate the comparability of surgical outcomes of RIRS performed under SA versus general GA for renal stones. Materials and methods: This was a retrospective, observational study in patients scheduled for RIRS in a single teaching hospital in Turkey. Inclusion criteria were age > 18 years and the presence of single or multiple renal stones. We recorded information concerning the site of lithiasis, the number of calculi, total stone burden, and the presence of concomitant ureteral stones or hydronephrosis. Results were evaluated in terms of surgical outcome, intraoperative and postoperative complications. Patients were followed-up until day 90 from discharge. Results: The data of 502 patients, 252 in GA group and 250 in SA group, were evaluated. The stone-free rate was 81% in the GA group and 85% in the SA group (p = 0.12). No cases of conversion from SA to GA were recorded. Complication rates were similar in the 2 groups (19% vs 14.5%, p = 0.15). Conclusions: In our cohort, RIRS performed under SA and GA was equivalent in terms of surgical results and complications.
