Pelvic arteriographies of 51 cases were performed by Seldinger's method with use of autoinjector under local anesthesia. Out of 51 cases, 10 cases were patients of non-prostatic disease (elder than 40 years old: control group), 21 cases were those of benign prostatic hypertrophy and 20 cases were those ofprostatic cancer. The results obtained are summarized as follows. 1) In control group, branches of inferior vesical artery and middle rectal artery distributed in area of the prostate were very fine, and branches of internal pudendal artery in one were not seen. Arterial network in the prostatic area were poor in all of the cases. 2) In cases of benign prostatic hypertrophy, inferior vesical artery was raised at level of lateral prostatic area. Branches of inferior vesical artery, middle rectal artery and internal pudendal artery distributed in area of the prostate were dilated as compared with the control group. Tumor stain (direct stainning of prostatic parenchyma) was visualized on later capillary phases in 5 cases out of 21 cases (23.7%). 3) In cases of prostatic cancer, branches of inferior vesical artery, middle rectal artery and internal pudendal artery distributed in area of prostate were very rich as compared with control group or those of benign prostatic hypertrophy. Branches of inferior vesical artery in area of the prostate showed dilatation, tortuosity, truncation, irregularity, blushing and pooling. In 10 cases out of20 cases (50%), tumor stain was visualized on earlier capillary phases. In 8 cases (40%), dilated branches of internal pudendal artery ascending to prostatic area was visualized with tortuosity or truncation, which had cancerous infiltration to seminal vesicle, urinary bladder or urethra.
