ABSTRACT
<p><b>OBJECTIVE</b>To discuss the value of grey scale ultrasonography and color Doppler of bi-planar transrectal ultrasound on the diagnosis of hyperplasia prostate gland (HPG).</p><p><b>METHODS</b>One hundred and ninety-two patients with HPG and 50 control subjects underwent abdominal ultrasound and TRUS examinations. The width (W), depth (D) and length (L) of the prostates and transitional zones were respectively measured. Each transitional zone index (TZI), i.e., the ratio of the transitional zone volume to the total prostate volume was calculated. Meanwhile, we observed the blood flow distribution in the prostates, calculated the parameters of hemodynamics such as peak systolic velocity (PSV), resistance index (RI) and pulse index (PI), and analyzed their correlations with TZI.</p><p><b>RESULTS</b>The revealing rates of cystic formation, calcium calculus and ejaculatory cyst and PSV, RI of arterial vessels in HPG were all significantly higher in the HPG patients than in the control subjects, and the revealing rates of all the above pathological changes but calcium calculus by TRUS were significantly higher than by abdominal examination. TZI of HPG was positively correlated with PSV, RI and PI.</p><p><b>CONCLUSION</b>Bi-planar TRUS can clearly display the normal and pathological structure of the prostate. And PSV, RI and PI may aid in the diagnosis of HPG and the assessment of the degree of prostatic proliferation.</p>
