Abstract

The Authors present a short review of the literature comparing transrectal ultrasound of the prostate (TRUS) and ultrasound guided biopsy and the results of 694 consecutive prostatic biopsies from their cohort. All the biopsies were US guided with an endorectal biplanar 5 MHz probe and transperineal samples were carried out with an 18 G needle (cutting length 22 mm) over the last 4 years. The histological exam showed 187 prostates affected by cancer while 112 had only inflammation. The operator's opinion, based on ultrasonography and integrated with a digital rectal exam (DRE) and a prostate specific antigen (PSA) blood test, was correct in 80% of the cases, with 90% sensitivity and 70% specificity. The positive prediction rate was 74% and the negative prediction rate was 89%.
