To analyze the indication criteria used for conducting seminal vesicles biopsies as well as the diagnostic capacity of other variables involved. We present the results of an observational and retrospective study (May 2006 - December 2012) using a sample of 140 patients to whom seminal vesicles biopsies was performed in a first set of prostate biopsy. They were patients eligible for curative treatment and presented any of the following criteria: PSA ≥15 ng/ml, suspicion of neoplastic seminal vesicle invasion on transrectal US, and/or suspicious node in the prostate base on DRE or transrectal US. Seminal vesicle invasion due to prostate cancer was detected in 22.2%. Patients with 3 criteria had T3b in 66.7% of cases. The criterion most associated with T3b was the presence of a suspicious node in the prostate base, with an association of 29.3% of cases. Variables analyzed that had shown a greater association with stage T3b were PSA density, the presence of suspicious DRE, the Gleason sum. Our seminal vesicle biopsy protocol has detected 22.2% of seminal vesicle invasion. The detection of a suspicious node at the prostate base has shown the greatest association with T3b.
