PurposeWe analyzed the results of patients who underwent percutaneous nephrolithotomy (PCNL) for management of kidney stone disease under combined spinal-epidural anesthesia and compared surgical parameters and outcomes with a matched control group who underwent PCNL under general anesthesia.Patients And MethodsA total of 82 patients were studied in two groups. Group 1 (n = 45) consisted of the patients who underwent general anesthesia, and group 2 (n = 37) comprised those who received combined spinal-epidural anesthesia.ResultsThe mean ages of patients in groups 1 and 2 were 45 +/- 15 and 44 +/- 15 years, respectively. The mean areas of the stones in groups 1 and 2 were 734 +/- 386 mm(2) and 731 +/- 394 mm(2), respectively. There were no significant differences between groups 1 and 2 among surgical parameters, including age, stone area, operative time, irrigation fluids, fluoroscopy time, delta hemoglobin, and hospitalization time (P = 0.439). At the end of the surgery, stone-free rates were 76% in group 1 and 81% in group 2; clinically insignificant residue fragments rates were 24% in group 1 and 19% in group 2. The difference was statistically insignificant between the groups (P = 0.543).ConclusionsWe consider that combined spinal-regional anesthesia is a feasible technique in PCNL operations because the efficacy and safety were not affected. Further investigations with larger series are needed.
