Continence after radical prostatectomy with bladder neck preservation

Bladder neck preservation during radical prostatectomy has been advocated for improving urinary continence. We evaluate bladder neck preservation looking at continence rates, surgical cancer control and bladder neck contracture.

A total of 40 patients underwent retropubic radical prostatectomy for clinically localized carcinoma of the prostate. The prostatic urethra was dissected in continuity with the bladder away from the lumen of the prostate, which allows for a true urethra-to-urethra anastomosis.

Continence was noted immediately in 26 patients, within 2 weeks in 9 and within 6 weeks in 3. Only 2 patients required pads 3 months postoperatively. Microscopic positive surgical margins were noted in 2 of 40 patients. In 1 patient the urethral margins were not involved with carcinoma. In the other patient the urethra was not the sole positive margin and microscopic positive margins were noted elsewhere. Early results of cancer control were good.

Early follow-up of this technique of radical retropubic prostatectomy suggest that preservation of the continence mechanism at the level of the bladder neck and prostatic urethra results in significantly improved postoperative urinary continence without adversely affecting cancer control.
