[en] Objective: To study the methods of prostatic arteriography and evaluate the arteriographic appearance of prostatic blood supply. Methods: Selective and super-selective prostatic arteriographies were performed in 62 patients with benign prostatic hyperplasia and prostatic cancer. Results: The prostatic blood supply originated mainly from inferior vesical artery or internal pudendal artery or prostatic artery (80%). Prostatic arteriography could be performed successfully with skillful catheterization and high resolution DSA. Conclusions: Prostatic arteriography is helpful for evaluating the origin and quantity of prostate vasculature and important to differentiate benign prostatic hyperplasia from prostatic cancer
