Pathologic features and clinical outcome after anatomic radical prostatectomy by transcoccygeal approach.
OBJECTIVE
A nonrandomized prospective study was conducted aimed at verifying the clinical outcome and pathologic features of a group of patients submitted to transcoccygeal radical prostatectomy.


METHODS
Radical transcoccygeal prostatectomy was performed at our institution in 26 patients after laparoscopic (24 cases) or open surgical (2 cases) pelvic lymphadenectomy. Eighteen patients were selected because they were considered to be at risk for nodal metastases on the basis of preoperative staging (prostate-specific antigen level of 20 ng/mL or greater and/or Gleason score greater than 5); the remaining 8 manifested incidental prostate carcinoma.


RESULTS
Intraoperative complications included rectal injury in 1 patient (3.8%) and massive blood loss in another. Transitory leakage at the site of the urethrovesical anastomosis and urethrorectal fistula occurred postoperatively in 2 patients. The rate of positive surgical margins was 26.9%. The mean follow-up time is 27 months (range 3 to 39 months). Total urinary continence was obtained in 21 patients (80.8%); 5 patients (19.2%) still require urinary pads. Four patients (15.4%) have experienced tumor recurrence evidenced only by increased serum prostate-specific antigen levels. Local tumor recurrence with positive biopsy of the urethrovesical junction was diagnosed in 3 patients (11.5%), and 1 (3.8%) experienced systemic tumor recurrence.


CONCLUSIONS
Radical transcoccygeal prostatectomy is a safe procedure for the surgical treatment of prostate cancer, both from a clinical and a pathologic point of view. Operative complication as well as pathologic features and clinical outcome reported in this series of patients must be related to selection criteria used in most cases. The exact role of radical transcoccygeal prostatectomy in the clinical setting has yet to be defined. According to these preliminary results, radical transcoccygeal prostatectomy should be further investigated in the treatment of incidental carcinoma after transurethral resection of the prostate or suprapubic prostatectomy and could become an elective indication in such cases.
