(Purpose) We report the clinical results and efficacy of laparoscopic radical prostatectomy for localized prostate cancer.
(Patients and methods) Between December, 1999 and June, 2000 we performed transperitoneal laparoscopic radial prostatectomy on 10 patients with T1 or T2 organ confined prostate cancer according to the techniques as described by Guillonneau et al. Different points were as follows: 1) We placed double J catheters during surgery to prevent ureteral injury. 2) We treated dorsal vein complex using an Endo-GIA-stapler. 3) We dissected the bladder neck from the prostate using an ultrasound scalpel in the manner to preserve the bladder neck.
(Result) We could not completed laparoscopic prostatectomy on two patients because of massive bleeding from drosal vein and consuming too much time to suture urethra-bladder anastomosis. The average operating time in all cases was 8.1 hours including 1.8hours in laparoscopic pelvic lymphadenectomy. The average estimated blood loss in all cases was 859ml. There were 2 surgical complications with bladder injury and port site hernia.
The histological examination revealed prostate cancer; pT2pNO in 8, pT3pNO in 2. The surgical margin and lymph nodes were negative in all patients. The duration of an indwelling catheter ranged from 5 to 40 days mean 17 days. The duration to recovery of normal micturition was 6 to 90 days, mean 40 days.
(Conclusion) Long-term follow-up and extensive studies are necessary to evaluate the efficacy of this procedure. It might provide shorter duration of an indwelling catheter and earlier recovery of normal micturition as compared with the conventional open surgery.
