Abstract
The pulmonary response to nephrectomy was studied in 16 patients undergoing laparoscopic (n = 8) or open (n = 8) nephrectomy using a standardized anesthetic technique. Although there was no significant difference between the two groups at 24 hours, postoperative pulmonary function measures (P = 0.02–0.03) and oxygenation (P = 0.03) were significantly better in the laparoscopic surgery group at 48 hours. The median opiate analgesic requirement (P = 0.02) and the number of nights spent in the hospital (P = 0.003) also were significantly lower in this group. The results of this study suggest that laparoscopic nephrectomy offers a real biological advantage in terms of postoperative preservation of lung function and that this might therefore be the safest technique for nephrectomy in patients with limited respiratory reserves.
