The prostate is often combined with other chronic illnesses, so the clinical treatment process also requires some necessary laboratory tests. The examination can also determine the presence of hematuria, urine sugar, bilirubin. Urine smears are microscopically examined and cultured to bacteria. When collecting urine, it must be done before the rectal finger examination to avoid prostate; ringing the examination results. 2, blood: blood routine and biochemical examination, for the infection caused by obstruction, uremia is very important, the degree of uremia is reflected in the degree of reduction of hemoglobin. In the case of urinary tract infection, the blood leukocyte count and classification is also a reference value for diagnosis and treatment. 3, kidney function measurement: patients with prostate hypertrophy can choose the following items for examination according to their specific conditions: (1) blood urea nitrogen, creatinine measurement (2) phenol red excretion test. (3) Indocyanine excretion test. (4) Urine concentration and dilution test. (5) General or high-dose intravenous urography. (4) Serum prostate-specific antigen (PSA) PSA determination: can be used to rule out the possibility of prostate cancer. It is important to note that in some cases PSA can be falsely positive, i.e. in the following cases, such as recent ejaculation, inflammation, ischemia or infarction of the prostate; benign prostatic hypertrophy and malignant prostate cancer. There are new methods for measuring free and bound PSA, which can improve the accuracy of differentiating between prostate hyperplasia and prostate cancer. 5. Urine flow rate test: The change in urine flow rate can indirectly measure the function of the lower urinary tract, which is very helpful to determine the lesion. Therefore, the urine flow rate can be measured at the initial diagnosis, during and after treatment to determine the efficacy of the treatment. Based on the non-invasive nature and clinical value of this test, it should be measured before, during and after treatment in places where it is available. 6, residual urine measurement: the residual urine in normal people is not greater than 10
The measurement of residual urine is one of the most important diagnostic steps, as the amount of residual urine can increase in patients with prostatic hypertrophy. It is recommended that the residual urine after urination should be measured during the initial evaluation of the patient and after treatment to determine efficacy. A simple and non-invasive method to detect this is by transabdominal ultrasound. Since the amount of residual urine in a person fluctuates widely, the initial examination should be repeated once if there is a large amount of residual urine for the sake of accuracy. 7. Zinc measurement: In prostate hypertrophy, plasma zinc levels are significantly higher. It can be used as one of the indicators to diagnose prostate hypertrophy.
