Ultrasound diagnosis of prostate 37mm*46mm*36mm represents that the patient may have prostate enlargement. The normal size of the prostate is 40mm*30mm*20mm, and 37mm*46mm*36mm indicates that the patient may have prostate enlargement. However, simply relying on the size of the prostate gland is not able to determine the specific situation of the prostate gland, and need to be combined with ultrasound judgment to assess the amount of residual urine, as well as prostate fingerprinting and tumor markers to determine the comprehensive judgment. Prostatic hyperplasia is closely related to aging, smoking and other factors, patients mainly manifested as frequent urination, urinary urgency, urinary incontinence, nocturia, urination difficulties. It is recommended that patients go to the urology department of regular hospitals for further diagnosis and treatment, and can take medication or choose surgery as prescribed by the doctor.
