Endoscope-assisted radical perineal prostatectomy.

Dissection of the bladder neck is particularly important in patients who have previously had prostate surgery due to hyperplasia. We describe an endoscope-assisted radical perineal prostatectomy (RPP) technique that facilitates the dissection of the prostate-vesical junction. The technique was employed in four patients with a history of transurethral prostate resection. Before dissecting the prostate from the bladder neck during RPP, we circumscribed the bladder neck perurethrally with a Collins knife. The remaining of the RPP procedure was performed via the traditional approach. The incision of the prostate-vesical junction with the Collins knife protected the bladder-neck integrity and made the dissection of this junction easier. The final pathologic diagnosis was organ-confined prostate cancer with negative surgical margins. All the patients had continence during a 6-month follow-up. The major advantage of this technique is to precisely locate the prostate-vesical junction under direct vision. Our modified technique may prove to be a simple, less invasive, and oncologically safe method to manage the bladder neck perurethrally.
