Abstract: Objective：To evaluate the efficacy and safety of transperitoneal laparoscopic radical nephrectomy with the modified Pfannenstiel incision. Methods: Between Aug. 2012 and Jul. 2013, the same surgeon performed transperitoneal laparoscopic radical nephrectomy for 12 patients with renal masses. The approach was usually performed through 3 ports or 4 ports placed in a traditional manner. After laparoscopic radical nephrectomy was completed, and the specimen was entrapped in a specimen retrieval bag, a 7 cm modified Pfannenstiel skin incision was made over the symphysis pubis, lateralized slightly toward the side of surgery. Results: All the procedures were completed without conversion to open radical nephrectomy. The operative time was 106 to 234 minutes and the blood loss was minimal. There was no intra- or post-operative complications. The pathological result was renal cell carcinoma. One patient died of multiple organ metastasis after 5 months. No recurrence was seen after 9 to 20 months’ follow-up. Conclusion:Laparoscopic radical nephrectomy with the modified Pfannenstiel incision where the kidney is removed offers the benefits of improved cosmesis over the traditional musclecutting extension of an upper abdominal, lateral port site. The modified Pfannenstiel incision combines the advantages of a low abdominal incision and improved cosmesis, and can be considered a potential alternative for traditional laparoscopic nephrectomy.
