Extraperitoneal laparoscopic radical prostatectomy for prostate cancer and functional recovery of urinary continence / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the surgical technique,urinary continence and clinical efficacy of extraperitoneal laparoscopic radical prostatectomy for prostate cancer. Methods This series included 28 cases of prostate cancer aged 60 -75 years (mean,68 years). The PSA level ranged from 0. 7 ng/ml to 23. 6 ng/ml. TNM classification showed T1N0M0 tumor in 11 cases, T2N0M0 tumor in 15 and T3aN0M0 tumor in 2. All cases underwent extraperitoneal laparoscopic radical prostatectomy. The functional reconstructive technique consisted of preservation of the urethral and bladder outlet sphincter muscles, and reconstruction of the bladder neck. Results All the operations were successful. The operative time was 180 - 380 min( mean, 240 min) ,and the blood loss was 400 - 1200 ml( mean,800 ml) . All the catheter were removed 2 weeks after surgery. Mild urinary incontinence occurred in 3 cases, and it improved after supportive treatment. The PSA level was 0. 02 -0. 10 ng/ml 3 months after operation. No recurrence of prostate cancer was found during the follow-up of 1 month-2 years. Conclusions Extraperitoneal laparoscopic radical prostatectomy is safe and effiective for the treatment of prostate cancer. It can be widely applied in clinical practice.
