Results: In contrast with hypertrophic group, the cancer group presented irregular shape and unclear edge, and obviously higher Vs, RI and PI. Con-clusion: The sonographic appearance and Vs. RI. PI have important value in distinguishing hypoechoic hypertrophic lesions and hypoechoic cancer lesions in the hypertrophic prostate inner glands.
