Synopsis:
The aim of this study was to assess the efficiency of two different methods of anesthesia on endocrine and metabolic responses of patients undergoing PNL (Percutaneus nephrolitotomy). Combined epidural analgesia, added to general anesthesia, may be a comfortable anaesthesia method in PNL with suppression of intraoperative and postoperative stress response and less pain scores in the early postoperative period.
