Effect of intra‐observer variation in prostate volume measurement on prostate‐specific antigen density calculations among prostate cancer active surveillance participants

Abstract

• Even among individuals who are highly experienced in TRUS-guided prostate volume measurement, significant intra-observer variation exists. However, this variability is not enough to affect one's eligibility for prostate cancer active surveillance when PSAD criteria are used. • The TRUS-guided prostate volume measurements remain a reliable method of assessing PSAD in patients with prostate cancer.
