Rg. Aarnink et al., STANDARDIZED ASSESSMENT TO ENHANCE THE DIAGNOSTIC-VALUE OF PROSTATE VOLUME .1. MORPHOMETRY IN PATIENTS WITH LOWER URINARY-TRACT SYMPTOMS, The Prostate, 29(5), 1996, pp. 317-326
BACKGROUND. The diagnostic value of prostate volume results has been e
valuated in patients with prostate problems of benign cause. METHODS.
For 247 patients, automated volume results were compared to manual res
ults of planimetric reference volume and of the classical ellipsoid fo
rmula. Also, transition zone volume was estimated and growth curves of
the prostate and prostate dimensions over age were investigated. RESU
LTS. Application of automated volume determination gives accurate resu
lts compared to the reference volume (Pearson correlation, R = 0.938).
The ellipsoid volume results were slightly less correlated (R = 0.921
). Average growth of the entire prostate was 1.7% per year, for the tr
ansition zone the growth was 4.3%. Compared to growth rates for a comm
unity-based population, comparable growth rates were found for our gro
up that had higher mean prostate volume. CONCLUSIONS. The results indi
cate that the age of onset of volume growth is the determining factor
in developing benign prostate enlargement not a change in growth rate.
