[Transurethral transumbilical laparoendoscopic single-site surgery for radical prostatectomy].

OBJECTIVE

To investigate the feasibility and advantages of transurethral transumbilical laparoendoscopic single-site surgery (TU-LESS) for radical prostatectomy.

METHODS

Five patients with prostate cancer underwent TU-LESS for radical prostatectomy, with a four-channel single-port device inserted into a 2. 5 cm periumbilical incision and another placed through the urethra, followed by analysis of the perioperative data.

RESULTS

All the operations were successfully accomplished, with neither conversion to open surgery nor additional channel. The mean operation time, intraoperative blood loss, and postoperative hospital stay were 168 min, 120 ml, and 15 d, respectively. No severe perioperative complications were observed. TNM stage classification manifested T2cN0M0 in 2 cases and T2bN0M0 in the other 3. Postoperative pathology showed no negative surgical margins in any of the cases.

CONCLUSION

TU-LESS is safe and feasible for radical prostatectomy and can reduce the complication of low urinary tract surgery by single-site laparoendoscopy.
