Prostate weight is the preferred measure of prostate size in radical prostatectomy cohorts

Abstract

OBJECTIVE: • To evaluate the accuracy of calculated prostate volume variables in a radical prostatectomy (RP) cohort, as many recent studies use these measures of prostate size instead of prostate weight. • To determine whether this accuracy could be improved by modifying the mathematical model used in the volume estimation. PATIENTS AND METHODS: • Patients who underwent RP for prostate cancer at our associated institutions had calculated specimen volumes and weights from RP specimens determined at one pathology institution and transrectal ultrasonography (TRUS) volumes were recorded preoperatively ( n = 236). • Correlation analysis was performed and errors were determined for calculated vol..
