There are many ways to detect the prostate gland, such as rectal fingerprinting, prostate fluid examination, prostate ultrasound, CT, MRI, etc. The prostate gland can be detected by rectal fingerprinting, prostate fluid examination, prostate ultrasound, CT and MRI. 1. Rectal fingerprinting: Rectal fingerprinting of the prostate gland can help to approximate the size and texture of the prostate gland, as well as initially determine whether there is any pressure and pain or nodules in the prostate gland. Rectal fingerprinting can also help to retain prostate fluid for prostate fluid examination. 2. Prostate fluid examination: Through routine examination of prostate fluid and culture of prostate fluid, it can be determined whether the patient has chronic prostatitis, or used to distinguish whether the patient has chronic bacterial prostatitis. 3. Prostate ultrasound: Prostate ultrasound can accurately measure the size of the prostate, and can also detect whether there are occupational lesions in the prostate. 4. CT, magnetic resonance examination: through further magnetic resonance and CT examination, we can clearly understand the peritoneum of the prostate and the surrounding structure, and can clarify whether the patient has prostate tumor. Regular prostate examination is the only way to detect prostate diseases in time, and it is recommended that patients go to the hospital in time when they feel unwell, so as not to delay their condition.
