[Value of transrectal ultrasound in determining the T-stage of prostate cancer].

Accurate preoperative staging of prostate adenocarcinoma is especially important before radical prostatectomy. The purpose of this prospective study was to investigate the staging accuracy of transrectal ultrasonography in prostatic adenocarcinoma. The results of the preoperative staging evaluation in 126 patients with endorectal ultrasound were compared with the histopathologic findings after radical prostatectomy. Correct staging by transrectal sonography was possible in 82 of 126 patients (65%). For stage pT3 tumors, sensitivity, specificity and positive predictive value were 69%, 51% and 82% respectively.
