Abstract Objective: To explore the value of transrectal ultrasound-mean color vessel density(TRUS-MCVD) in benign prostate hypertrophy(BPH) and prostate cancer(PCa). Materials and Methods: Twenty-two cases of PCa and 60 cases of BPH were examined with transrectal color power angiography(TR-CPA), MCVD of focal lesions were calculated with Auto CAD2004 software and had been compared with each other. Results of PCa were compared with their clinical stages. Results: MCVD of PCa group were significantly higher than that of the BPH group(0.2400±0.0851 vs 0.0857±0.2867, P<0.01). There was significantly difference between stage D and stage A, B, C in PCa(0.3488±0.0522 vs 0.2170±0.0354, 0.2231±0.0814, 0.2252±0.0924, P<0.05). Conclusion: The TRUS-MCVD can provide objective evidence for differential diagnosis of PCa and BPH, moreover, it is helpful in predicting the prognosis of PCa before treatment.
