Is the density of transition zone prostate tissue truly 1 gram per milliliter?-an evaluation of HoLEP specimens

Background

Prostate volume is assumed to equal prostate weight (PW), based on a 1:1 conversion between the milliliter (mL) and gram (g). While the 1:1 conversion holds for pure water, the density of transitional zone prostate tissue has not been studied. The aim of this study was to evaluate prostate density (PD) and the factors that affect it.
