[Single-port laparoscopic surgery for radical nephrectomy: report of 22 cases].

Objective: [corrected] To evaluate the method and technique of single-port laparoscopic radical nephrectomy.

Methods: Form January 2009 to September 2011, 22 patients with renal carcinoma were treated with single-port laparoscopic radical nephrectomy. An incision about 5 cm in length was made through the umbilicus or in the postaxillary line under the 12th rib to establish the peritoneal or retroperitoneal working space. A single-port cannulation was deployed and the operation was carried out using standard and crooked laparoscopic equipment.

Results: The operations were completed successfully in all the 22 cases without conversion to open surgery, but additional trocar was needed in 5 cases. The mean operative time of radical nephrectomy was 150 min (90-240 min). The mean postoperative hospital stay was 7.6 days (3-15 days). The operation left a roughly 5-cm-long scar in all the cases.

Conclusion: Single-port laparoscopic radical nephrectomy is safe and feasible with good cosmetic effect and shows much potential in radical resection of renal carcinoma.
