Comparison of Regional and General Anesthesia in Ureterorenoscopic Management of Distal Ureteral Stones: A Prospective Randomized Study

Objective: To compare the effects of regional (spinal) and general anesthesia (GA) on surgical outcomes, perioperative complications, postoperative pain, and surgeon comfort in patients undergoing ureterorenoscopy (URS) for distal ureteral stones. Method:This prospective, randomized clinical study included patients undergoing URS for distal ureteral calculi at a tertiary academic center between January 2024 and March 2025.Patients were allocated to either the GA or regional anesthesia (RA) group.Baseline demographics, operative parameters, postoperative pain scores [visual analogue scale (VAS)], analgesic requirements, and surgeon comfort were recorded and statistically compared.Results: A total of 180 patients were included (90 in each group).Demographic and stone characteristics were similar between the two groups.The mean operative time was significantly shorter in the GA group (22.98.3 vs. 27.99.5 min, p=0.001).VAS were significantly lower in the GA group at the 6 th and 12 th hours: median VAS scores were 5.0 [interquartile range (IQR) 4.0-6.0]vs. 6.0 (IQR 5.0-6.3) at 6 hours (p=0.001), and 4.0 (IQR 3.0-5.0)vs. 6.0 (IQR 4.0-6.8)at 12 hours (p=0.001),respectively.Surgeon comfort scores were also significantly higher in the GA group (p=0.001).Success and complication rates did not differ significantly between groups.Ama: Distal reter talar iin reterorenoskopi (URS) uygulanan hastalarda blgesel (spinal) ve genel anestezinin (GA) cerrahi sonular, perioperatif komplikasyonlar, postoperatif ar ve cerrah konforu zerindeki etkilerini karlatrmaktr.Yntem: Bu prospektif, randomize klinik almaya
