Objective: To report our prelimilary experience of laparoscopic radical prostatectomy (LRP) for clinically localized prostatic cancer.Methods:23 cases with localized prostatic cancer underwent LRP in our institution from October 2000 to August 2003. The median age was 64.5 years old, the median PSA was 13 ng/ml and median Gleason score of biopsy specimens was < 7. The operations were performed according to Montsouris technique. Briefly, operations were carried out transperitonealty, combining posterior and anterior approachs to the prostate, transecting the bladder neck, lateral dissection of the prostate, urcthrovesical anastomosis, completing the operation.Results:No death and no conversion rate were observed in this series of 23 cases of LRP. No re-intervention was needed. The median operating time was 325 minutes (range 270 to 660 min) including the lymphadenectomy phase that was considered necessary in the case whose PSA value was 51ng/ml and pathological reading was negative to thoses lymph nodes; The median intraoperative blood loss was 430 ml(rang 200 to 1100 ml). Postoperative bladder catheterization time was 20 days. Surgical positive margin was found in I case of pathlogical stage of pT 2b and Casodex 50 mg had been used on this case for 3 mon after the PSA value was < 0.2 ng/ml. Postoperation follow-up of 3 to 24 mo. showed no signs of complications such as urethral stricture or urine incontinence. The PSA concentrations was < 0.3 ng/ml in all cases.Conclusions: LRP provides a clear and magnified anatomical image to allow a more precise and safer dissection.
