The sensitivity of transrectal ultrasonography was 86 per cent but the specificity was only 41 per cent. Tumors less than 1cm. in diameter were most difficult to detect by transrectal ultrasonography. The positive and negative predictive values of transrectal ultrasonography were 36 and 89 per cent, respectively. Abnormal scans that strongly suggested carcinoma were present in 10 per cent of the men who had a normal digital examination but no biopsy was performed. Transrectal ultrasound is a sensitive method to detect all but small prostatic tumors and it can detect tumors that are not evident by digital examination. To date, however, transrectal ultrasonography may be difficult to use for routine screening in the United States because of the low positive predictive value. Nevertheless, further investigation of this technique is warranted to define its role in improving the diagnosis of prostatic cancer. © 1986 by The American Urological Association Education and Research, Inc.FiguresReferencesRelatedDetailsCited byAARNINK R, BEERLAGE H, DE LA ROSETTE J, DEBRUYNE F and WIJKSTRA H (2018) TRANSRECTAL ULTRASOUND OF THE PROSTATE: INNOVATIONS AND FUTURE APPLICATIONSJournal of Urology, VOL. 159, NO. 5, (1568-1579), Online publication date: 1-May-1998.Gohagan J, Prorok P, Kramer B and Cornett J (2018) Prostate Cancer Screening in the Prostate, Lung, Colorectal and Ovarian Cancer Screening Trial of the National Cancer InstituteJournal of Urology, VOL. 152, NO. 5 Part 2, (1905-1909), Online publication date: 1-Nov-1994.Terris M, Freiha F, McNeal J and Stamey T (2018) Efficacy of Transrectal Ultrasound for Identification of Clinically Undetected Prostate CancerJournal of Urology, VOL. 146, NO. 1, (78-84), Online publication date: 1-Jul-1991.Hinman F (2018) Screening for Prostatic CarcinomaJournal of Urology, VOL. 145, NO. 1, (126-129), Online publication date: 1-Jan-1991.Chodak G (2018) Editorial CommentsJournal of Urology, VOL. 145, NO. 1, (129-130), Online publication date: 1-Jan-1991.Andriole G, Coplen D, Mikkelsen D and Catalona W (2018) Sonographic and Pathological Staging of Patients with Clinically Localized Prostate CancerJournal of Urology, VOL. 142, NO. 5, (1259-1261), Online publication date: 1-Nov-1989.Shinohara K, Wheeler T and Scardino P (2018) The Appearance of Prostate Cancer on Transrectal Ultrasonography: Correlation of Imaging and Pathological ExaminationsJournal of Urology, VOL. 142, NO. 1, (76-82), Online publication date: 1-Jul-1989.Waterhouse R and Resnick M (2018) The Use of Transrectal Prostatic Ultrasonography in the Evaluation of Patients with Prostatic CarcinomaJournal of Urology, VOL. 141, NO. 2, (233-239), Online publication date: 1-Feb-1989.
