Laparoendoscopic single-site (LESS) radical prostatectomy (RP) has been performed through different approaches. A new DuoRotate manual system developed by Richard Wolf (KeyPort; Richard Wolf GmbH, Knittlingen, Germany) can be applied to RP.
Our aim was to describe the surgical technique and report early outcomes of KeyPort LESS-RP to determine if this procedure is feasible and safe.
Design, setting, and participants
Prospective study performed between October 2011 and January 2012 to standardize LESS-RP. A total of 31 procedures were performed (10 with and 21 without neurovascular preservation, 8 with and 23 without pelvic lymph node dissection).
LESS-RP was performed using the methods outlined in the manuscript. All patients underwent LESS RP by the same surgical team. Access was achieved via a tri-channel reusable KeyPort and one 3.5-mm extra port to facilitate urethrovesical anastomosis and drainage extraction.
Outcome measurements and statistical analysis
Preoperative, perioperative, and pathologic outcomes data are presented.
Results and limitations
The mean age of the patients was 64 yr; mean body mass index: 30.7
The KeyPort system allows performance of umbilical RP with few complications, a low positive-margin rate, excellent aesthetic results, and very low postoperative pain levels.
