Rib resection for live-donor nephrectomy

Living-related kidney transplants yield more favorable results than cadaveric kidney transplant. Although multiple techniques have been described for living-related donor nephrectomy, operation is generally performed subcostally in lateral decubitis position or by an 11th or 12th rib resection. Recently laparoscopic donor nephrectomy is getting popular. The aim of this study is to determine the rib resection increase the morbidity or not. Between 1997 and 2004 in our center 118 living donor nephrectomies were performed. 15 of these patients did not come to follow-up controls. This study consists of 103 patients: 11th rib resection (30 patients) determined as group I, 12th rib resection (52 patients) determined as group II, subcostal incision (21 patients) determined as group III. All these three groups were compared with each other according to operation time, pleural or peritoneal defect, pneumothorax, blood transfusion, wound infection, length of hospital stay, postoperative analgesic requirement, return to threshold activities and incisional hernia. Patients whose 11th rib was removed had the shortest operation time. But pain due to surgery continued more than others in this group of patients. The risk of developing incisional hernia was seen most in patients who had subcostal incision. In this group of patients incidence of incisional hernia was 4 (19%). None of the patients had wound infection. We also did not experience any pneumothorax and blood transfusion requirement. Peritoneal or pleural opening occurred in 4 out of 103 patients accidentally and there was no difference between groups. There was also no difference between groups in terms of returning back to daily activation. Morbidity of nephrectomy done with removal of 12th rib was less compared with other groups. Resection of 11th should be reserved for patients with high residing kidneys and also for those with a polar artery of the upper pole.
