[Expanded, radical perineal prostatectomy].
One hundred and twenty-five consecutive patients with prostate cancer underwent an extended, radical perineal prostatectomy according to the technique described by VE Weldon. This technique was modified by an initial complete mobilization of the posterior aspect of the prostate and seminal vesicles from the rectum and pelvic wall, incision of the endopelvic fascia, and partial resection of the dorsal vein complex after suture ligature. The perioperative morbidity was low. An operative revision was necessary in four (3.2%) patients because of arterial bleeding from a drainage channel (n = 1), wound infection (n = 2), and rectocutaneous fistula (n = 1). The in-dwelling catheter was removed on day 4-8 in 104 (83%) patients. Positive surgical margins were diagnosed in 22 (17.6%) patients only. These patients had pT3 (n = 17) and pT4 (n = 5) tumors with a Gleason score > or = 7 (n = 17) mostly; extensive, multifocal capsular penetration (n = 18); seminal vesicle invasion (n = 11); and lymph node metastases (n = 4). The unifocal positive margins were localized at the apex (n = 3), dorsolateral (n = 6) aspect, and bladder neck (n = 4). In nine patients, multifocal positive surgical margins were noted. The risk for a positive surgical margin depends on the serum PSA level, Gleason score, and tumor volume. In case potency preservation is not considered, the extended, radical perineal prostatectomy with the above mentioned modifications should be considered to guarantee a low rate of surgical margins.
