We found that 95 (28%) had PCa and 115 (34%) had UCa involvement of prostate. The rate of incidental prostate cancer was 21% and 31%, respectively, from two study periods (2004\u20132008 and 2009\u20132014). Among the 95 patients with PCa, 19 (20%) had Gleason score of \u22657, nine (10%) had PCa tumor volume &gt;0.5\u2009cc, and eight (8.4%) had extracapsular extension. Of the 115 with prostatic UCa, 61 had prostatic urethra and\/or periurethral prostatic duct involvement only, while 54 had prostatic stromal invasion.
