The relationship between transitional zone volume, total prostate volume, serum free and total prostate specific antigen rate in the patients with bening prostatiic hyperplasia

The patients included in the study were between the ages of 42 and 89 at the time of diagnosis, and the mean age was 63,4. The patients were divided into four groups according to their ages. In these groups, free - total PSA, transition zone volume, total prostate volume and rate were analyzed.The clinical findings were as follows : Mean PSA 10.08 ng/ml, mean free PSA 2.1 ng/ml, mean prostate volume 64.93 ml, mean transitional zone volume 47.47, mean free to total PSA rate % 20.14, mean ratio of transitional prostate volume to the whole prostate volume % 71.32.The age and prostate volume of patients were significantly correlated with increasing age, especially free PSA is found to be correlated. However, the relation between Free/Total PSA and transition zone volume/ total prostate volume was statistically significant but not highly correlated. According to these results, the best approach to show the prostate volume is TRUS. However, when there is no possibility of applying TRUS, free PSA levels can be used to estimate the prostate volumes.
