Improvement of continence by laparoscopic reconstructive radical prostatectomy / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the therapeutic effects of functional reconstructive technique of laparoscopic radical prostatectomy (LRP) for organ confined prostate cancer. Methods From October 2000 to September 2004,54 patients with organ confined prostate cancer (TNM stage of T 1b-T 2) underwent LRP.After completion of the first group of 15 consecutive cases (group A) by Monstouris techniques, the functional reconstructive surgical technique, which is basically composed of anatomical radical prostatectomy,was introduced to LRP in the second group of 39 consecutive cases (group B).These techniques mainly consisted of preservation of urethral and bladder outlet sphincter muscles,reconstruction of bladder neck,and fine anastomosis between urethra and bladder neck with fixation of anterior wall of anastomotic stoma and retropubic vascular complex.The operative time, bleeding volume,complications,continence recovery time and PSA level were comparatively analyzed between the 2 groups. Results All the operations were successful in 54 patients.In group A and group B,the mean operative time was 390 min(range,270-660 min)vs 240 min(range,180-360 min);the mean bleeding volume was 430 ml(range,200-1100 ml) vs 160 ml(100-400 ml);the complication rate was 40% (6/15) vs 13% (5/39) and the continence recovery time was on average 6 months vs 3 months,respectively. There were statistically significant differences in these parameters between the 2 groups (P
