Relação entre os níveis do antígeno prostático específico e o volume da próstata na idade de 40 a 90 anos.

Abstract

The aim of this study was to evaluate the levels of total prostate specific antigen (tPSA) and prostate volume obtained by endorectal ultrasound, as well as the correlation between tPSA and prostate volume in healthy subjects age 40-90 years. This is an observational, prospective, cross-sectional study in healthy men evaluated for prostate by endorectal ultrasonography during the period 2007-2012. The variables analyzed were tPSA levels obtained by immunometric assay and prostate volume obtained by endorectal ultrasound We observed that the tPSA increased in the age group 71-80 years (p <0.05). The prostate volume increased in the age groups 61-70 years and 71-80 years (p <0.05). Positive correlation of increased prostate volume with tPSA in the age groups 50-60 years (p = 0.0042), 61-70 years (p <0.001) and 71-80 years (p <0.0040). Our findings are important for comparison of tPSA and prostate volume of healthy individuals presenting with prostate disease.
