Since the original reports of transrectal by direct puncture of the prostatic gland under television monitoring and/or cineradiography, attempts have been made to utilize this technique in various conditions of the prostate. It was confirmed by our observations that the benign hyperplasia of the prostate was a well vascularized mass prostatographically. For this reason, we thought that the prostatogram and phlebogram of the veins surrounding the prostatic gland were visualized immediately and only transiently following injection of small volumes of contrast material into the parenchyma of the prostate. If the contrast material remained longer in the prostatic gland, the prostatogram would delineate the prostate more clearly and it might be more useful for the diagnosis of many clinical conditions, especially for the detection of malignancy in the prostate. For this purpose, we have examined the effect of epirenamine, a temporary but powerful vasoconstrictor, in the transrectal prostatograms which assures greater certainty of diagnosis. We also hoped to evaluate the effect of epirenamine. The effect of intra-prostatic epirenamine injection in transrectal prostatography was studied in benign prostatic hyperplasia. Time and dose criteria were defined and prostatographic findings were stated. The greater vasoconstriction produced by this method in periprostatic and intra-prostatic vessels, as compared with that without epirenamine, was substantiated. The small-dose contrast material prostatography was made possible by reducing prostatic circulation by intra-prostatic injection of epirenamine just prior to the adenographic phase of transrectal prostatography.
