Laparoscopic extraperitoneal radical prostatectomy / 中华泌尿外科杂志

ABSTRACT

Objective To present the experience of laparoscopic extraperitoneal radical prostatectomy and evaluate its safety and efficacy. Methods A total of 91 patients diagnosed with localized prostate carcinoma were admitted from February 2003 to June 2008. The level of serum PSA ranged from 7. 5 - 47. 0 ng/ml(mean 14. 0 ng/ml). The volume of the prostate ranged from 35 - 75 ml(mean 52 ml). Biopsy was performed before the operation and the pathological results revealed prostate carcinoma with Gleason score no more than 8. CT, MR and ECT revealed there was no lymph node or seminal vesicle involvement and there was no bone metastasis. The procedures were performed with an-tegrade techniques and pelvic lymphadenectomies were performed in 32 cases and nerve-sparings were performed in 11 cases. Results The operation duration ranged from 105 - 270 min (mean 173 min). Intraoperative blood loss was 110 - 1200 ml(mean 315 ml). Incontinence occurred in 19 cases in early stage and 18 cases recovered within 3 months. Positive surgical margin occurred in 11 cases. There was no complication of urethra stricture during 3 - 30 months' follow-up. No lymph node was involved in 32 cases with pelvic lymphadectomy. Five of the 11 cases received nerve-sparing prostatectomy had normal erectile function during the follow-up. Conclusions Laparoscopic extraperitoneal radical prostatectomy is a safe, effective and efficient surgical procedure with the minimal invasion, less morbidity and rapid recovery. Laparoscopic radical prostatectomy is emerging as an alternative to open radical prostatectomy.
