Laparoscopic radical prostatectomy: surgical, oncological and functional outcomes.

OBJECTIVE

To report the first results of laparoscopic radical prostatectomy (LRP) at our institution.

MATERIAL AND METHODS

The surgical, functional and oncological outcomes of all patients who underwent LRP at Helsinki University Central Hospital between May 2002 and May 2006 were prospectively evaluated. The first eight patients were operated transperitoneally and the next 72 extraperitoneally.

RESULTS

The mean operative time was 328+/-73 min (range 210-510 min). The mean estimated blood loss was 769+/-906 ml (range 50-5500 ml), and 18 patients (22.5%) had transfusions. The mean catheterization time was 13.2+/-4.0 days (range 9-35 days). Mean hospital stay was 5.7+/-3.1 days (range 3-15 days). Nineteen patients (23.8%) had perioperative complications. The conversion rate to open surgery was 11.3% and 6.3% required an immediate re-operation. Three anastomotic strictures (5.7%) and two cases of ileus (3.8%) were observed. The cancer was intracapsular (pT1-2) in 68 patients (85.0%) and extracapsular (pT3-4) in 12 (15.0%). Positive surgical margins were noted in 20 patients (25.0%) in total: 17.6% of pT1-2 cases and 66.7% of pT3-4 cases. Prostate-specific antigen recurrence (> or =0.2 ng/ml) was noted in 5/53 patients (9.4%), who were followed for >12 months. The continence rate (no daily pad use) was 86.8% and the potency rate was 34.6% at 12 months.

CONCLUSIONS

The surgical, functional and oncological results of our first LRPs compare fairly well with the early experience of others. LRP is feasible outside high-volume centers but the learning curve is expected to be long.
