Prostatitis can be diagnosed by laboratory tests, imaging tests and other tests. 1. Laboratory tests: patients with prostatitis will have elevated levels of leukocytes in the urine routine, as well as elevated levels of leukocytes in the prostate fluid, and a positive lecithin microsomal presentation in the prostate massage fluid test can also be diagnosed as prostatitis. 2. Imaging tests: ultrasound, CT and other imaging tests can also be done. Ultrasound of the prostate can reveal increased volume in patients with acute prostatitis, while chronic prostatitis can be visualized by rectal ultrasound of the prostate to obtain a complete image of the prostate. 3. Other tests: prostate examination can also be abnormal in patients with prostatitis through tissue pressure measurement in the prostate, puncture biopsy of the prostate, and cystourethroscopy. In conclusion, prostate examination is very common, and it is recommended that the examination be conducted under the guidance of a doctor. If prostatitis is diagnosed, it is recommended that standardized treatment be carried out as early as possible in order to reduce the adverse effects of the disease.
