Is transperineal prostate biopsy more accurate than transrectal biopsy in determining final <scp>G</scp> leason score and clinical risk category? A comparative analysis

Abstract

In this series, TTB more accurately predicted clinical risk category than TRUSB. TTB should be considered before active surveillance, to ensure that occult higher risk disease has not been under diagnosed. Upgrading and increase in clinical risk category was relatively common in each group highlighting the need for improved pretreatment staging accuracy.
