prostate intraepithelial neoplasia, ultrasound investigation, dopplerography


The article is dedicated to the problem of prostate intraepithelial neoplasia ultrasound diagnostics. The objective was to determine specific ultrasound features of PIN. Transrectal ultrasound and Doppler data of 166 patients with high grade and low grade PIN were analysed. Such ultrasound features as echogenicity (hypo-, iso- and hyperechogenic) and vascularisation grade (hypo-, iso- and hypervascularisation) of prostate samples with PIN were compared. There was no any statistically confirmed difference in echogenicity and vascularisation determined between high and low grade PIN and normal prostate tissue. Investigation data indicate low significance of transrectal ultrasound and dopplerography in diagnostics of prostate intraepithelial neoplasia.
