Comparison of ureterorenoscopy (URS) procedure performed under general and spinal anesthesia in ureteral stones

Aim: The objective of this study was to evaluate records of the patients who underwent ureterorenoscopy under general and spinal anesthesia and to determine whether the type of anesthesia affected the success of the operation and complications. Material and Methods: Medical records of 1548 patients who underwent ureterorenoscopy [URS] were retrospectively reviewed for 10 years. Patients were divided into two groups according to the type of anesthesia as general anesthesia and spinal anesthesia groups. Routine monitoring was performed in the operating. Two groups were compared in terms of demographic data, preoperative, operative and postoperative characteristics. Results: The mean age was statistically significantly higher in the general anesthesia group [49.57±15,31] compared to the spinal anesthesia group [47.21±13.19]
