Abstract
Prostate evaluation after abdominoperineal resection is hampered by the inability of the physician to perform digital rectal examination and transrectal ultrasound. Laboratory evaluation alone is not specific, and computerized tomography and magnetic resonance imaging are costly while yielding unclear results. We evaluated 23 men with prostate specific antigen, prostatic acid phosphatase and transperineal ultrasound of the prostate, using an elevated prostate specific antigen level and/or hypoechoic focus as indications for biopsy. Ten men underwent transperineal biopsy of the prostate and in 2 biopsies revealed prostate carcinoma. Transperineal ultrasound allows for accurate evaluation of the prostate in men following abdominoperineal resection as well as accurate biopsy when indicated.
