[Advances in the studies of morphological histology and imaging of benign prostatic hyperplasia]

Benign prostatic hyperplasia (BPH) is a familiar usually involves senile males. In recent 50 years, the incidence of BPH in China has been increasing. The morphological histology of hyperplastic prostate showed the volume enlarged and weight increase, and the hyperplastic part was mainly located in transitional zone. Researchers at home and abroad studied the tissue characteristics of hyperplastic prostate by routine and special staining coupled with computer-assisted quantitative image analysis system, and found that the proliferation was mainly occurred in interstitial tissue of prostate. The imaging examination is an important assistant method to diagnose BPH. Especially, Transrectal ultrasound and magnetic resonance imaging can displayed hyperplastic prostate more clearly.
