USEFULNESS OF CONVENTIONAL TRUS AND TRANSRECTAL VOIDING URETHROSONOGRAPHY IN SUSPICION OF LOWER URINARY TRACT OBSTRUCTION AFTER RADICAL RETROPUBIC PROSTATECTOMY

Purpose: To evaluate usefulness of conventional TRUS of post prostatic fossa as a diagnostic tool for detection of strictures between bladder neck and bulbar urethra in comparison with transrectal voiding urethrosonography (TVUS). Methods and Materials: Both TRUS and TVUS were performed in 52 patients who underwent radical prostatectomy at least 12 months earlier. Using 10MHz transrectal probe (8808; Viking 2400 B&K Medical) bladder neck, post prostatic fossa and sphincteric urethra were visualized in sagittal and transverse planes. In every case a detailed description of bladder neck shape, vesical triangle, ti…
