Using linear-array transrectal prostate sonography, malignant lesions in 43 patients and benign lesions in 74 patients were evaluated. Prostate sonography was sensitive to textural changes produced by both benign and malignant diseases. However, there was considerable overlap in the sonographic appearances of benign and malignant lesions, and there were no sonographic features that reliably predicted malignancy. Hyperechoic areas were present in 58% of the carcinomas, while 19% were purely hypoechoic. Lesions containing hypoechoic foci that were posterior or posterolateral had a high incidence of cancer. The results confirm the need to biopsy all suspicious palpable lesions of the prostate.

D008297 Male Males
D011467 Prostate A gland in males that surrounds the neck of the URINARY BLADDER and the URETHRA. It secretes a substance that liquefies coagulated semen. It is situated in the pelvic cavity behind the lower part of the PUBIC SYMPHYSIS, above the deep layer of the triangular ligament, and rests upon the RECTUM. Prostates
D011468 Prostatectomy Complete or partial surgical removal of the prostate. Three primary approaches are commonly employed: suprapubic - removal through an incision above the pubis and through the urinary bladder; retropubic - as for suprapubic but without entering the urinary bladder; and transurethral (TRANSURETHRAL RESECTION OF PROSTATE).

D011470 Prostatic Hyperplasia Increase in constituent cells in the PROSTATE, leading to enlargement of the organ (hypertrophy) and adverse impact on the lower urinary tract function.
