The easiest way to examine the prostate is through anal fingering, which can check the size, shape, and presence of pressure and pain of the prostate, thus making a preliminary diagnosis and screening for prostate disease. It is also possible to massage the prostate gland and examine the changes in the properties and composition of the prostate fluid. The B ultrasound is a common method of examining the prostate, with transrectal probing and suprapubic abdominal probing, which can make accurate measurements of the prostate with an error of no more than 5%. It has the advantages of being easy, non-invasive, non-invasive and fast. X-rays have an important value in the diagnosis of prostate diseases. For example, plain films can detect the presence of calcifications or stone shadows in the prostate. CT examinations are important for the differential diagnosis of prostate disease. A prostate puncture biopsy is useful to determine the nature of the prostate mass and is extremely helpful in identifying the histotype and cytologic features of prostate tumors. It can be done by transrectal needle aspiration biopsy or by perineal puncture biopsy, which is painful and invasive, but very necessary. In addition, urodynamic examination of the lower urinary tract is very helpful in diagnosing prostatic hyperplasia, and cystoscopy allows direct observation of the posterior urethra, seminal frenulum, and mid- and lateral lobe hyperplasia of the prostate, which is also very important in diagnosing prostate disease.
