title: Single-port laparoscopic surgery in urology: initial experience.
abstract: OBJECTIVE
  To present our initial experience with single-port laparoscopic urologic surgery using the Uni-X Single Port Access Laparoscopic System, a single port, multichannel cannula, with specially designed curved laparoscopic instrumentation.
  
  
  METHODS
  We performed single-port laparoscopic surgery in 10 patients, including renal cryotherapy in 4, wedge kidney biopsy in 1, radical nephrectomy in 1, and abdominal sacrocolpopexy in 4. For the transperitoneal approach, the multichannel port was inserted transumbilically, and for retroperitoneoscopy, the port was inserted at the tip of the 12th rib. Data were collected prospectively into our institutional review board-approved data registry.
  
  
  RESULTS
  Since September 25, 2007, a total of 10 patients have undergone single-port laparoscopic surgery for various upper abdominal and pelvic pathologic findings. All cases were completed successfully, without conversion to a standard laparoscopic approach. The total operative time for the various kidney procedures was 2.5 hours (range 2 to 3.2) and was 2.5 hours (range 2 to 3) for sacrocolpopexy. The mean blood loss was 100 mL for the renal procedures and 90 mL for sacrocolpopexy. The hospital stay was 2.8 days (range 1 to 8) for the kidney procedures and 2 days for sacrocolpopexy. One complication occurred in a patient with baseline congestive heart failure who underwent cryoablation and required oxygen mask ventilation postoperatively that delayed her hospital discharge for 1 week. The same patient, who was anemic preoperatively, was transfused with 3 U of packed red blood cells, although the postoperative computed tomography scan revealed a small perinephric hematoma.
  
  
  CONCLUSIONS
  Single-port laparoscopic renal cryotherapy, wedge kidney biopsy, radical nephrectomy, and abdominal sacrocolpopexy are safe and feasible. Additional experience and continued investigation are warranted.
