Prostatic specific antigen and benign prostatic hyperplasia.

The aim of this study on patients (n = 51) with urodynamically proven obstruction was to search for correlations between serological levels of prostatic specific antigen (PSA) and age of patients, volume of prostate and prostatic morphology as evaluated on transurethral resection specimens. No correlations could be found between PSA levels and morphological parameters such as degree of inflammation and relative degree of stromal or epithelial hyperplasia. Significant correlations were demonstrated between PSA levels and age of patients and prostatic volume.
