Abstract
Purpose:
We 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 Methods:
A 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.
Results:
The 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 mm2 and 731 ± 394 mm2, 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).
Conclusions:
We 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.
