PURPOSE: The purpose of this study was to evaluate the relationship between diffuse hypoechoic appearance of the prostate, which is characterized by indistinguishable boundaries between the peripheral zone and the inner gland, and the diagnosis of prostate adenocarcinoma established by transrectal prostate biopsies. MATERIALS AND METHODS: We performed transrectal ultrasonography in 143 male patients with serum prostate specific antigen levels above 4 ng/ml. Randomized biopsies were carried out in all patients. RESULTS: Prostate adenocarcinoma was diagnosed in 36.4% of the patients. Twenty-one (95.4%) out of 22 patients with diffuse hypoechoic appearance of the prostate had positive biopsies for prostate adenocarcinoma. CONCLUSION: Ultrasound diffuse hypoechoic appearance of the prostate is a significant criterion for suspecting adenocarcinoma, since 95.4% of the patients exhibiting this ultrasound findings presented positive biopsies.
