Introduction:
The objective of this study was to compare the results in terms of continence and quality of life between retropubic radical prostatectomy and laparoscopic radical prostatectomy, performed according to the same principle of retrograde dissection from the apex.
Material And Method:
The series was composed of 120 patients undergoing retropubic radical prostatectomy and 131 patients undergoing laparoscopic radical prostatectomy performed in the Limoges hospital, urology and andrology department, between January 2002 and September 2005. Continence was evaluated by anonymous self-administered questionnaire sent to the patient's home. Pain was evaluated by visual analogue scale and narcotic consumption. Predictive factors of continence were analysed.
Results:
The two groups were comparable in terms of pathological stage, Gleason score and age. The laparoscopy group comprised more patients with a history of transurethral resection of the prostate and more obese patients. No significant difference was observed between laparoscopy and laparotomy for degree of continence (71% versus 76%; p>0.05), time to return of continence (13 weeks versus nine weeks; p>0.05) and rate of mild (14% versus 13%), moderate (7% versus 6%) and severe (7% versus 5%) urinary incontinence. The anastomosis secondary stenosis rate was also identical in the two groups. Age was found to be a predictive factor for continence, especially for the mean time to return periods of continence. The patient's weight, prostate weight and TNM stage were not predictive factors for incontinence. The incontinence rate was 40% for salvage prostatectomies after radiotherapy. The mean duration of bladder catheterization was 6.9 days in the laparoscopy group and 7.2 days in the laparotomy group. Narcotic consumption was significantly lower in the laparoscopy group (21 mg versus 36 mg; p<0.05).
Conclusion:
Laparoscopic radical prostatectomy appears to give the same results in terms of continence as retropubic radical prostatectomy. However, these procedures were the first laparoscopic prostatectomies performed in the department, suggesting that, with greater experience, the results of laparoscopy could become superior to those of laparotomy. The laparoscopic technique also appeared to provide better patient comfort by decreasing postoperative pain.
