Patients with prostate hypertrophy often have other chronic disorders in combination, so the clinical treatment process also requires some necessary laboratory tests.
1, urinalysis.
The routine urine examination of patients with prostate hypertrophy can sometimes be normal, and now urinary tract infections can be seen in red and white blood cells, proteinuria, pus urine and alkaline urine. 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.
Routine blood and biochemical examination is very important for those with infection and uremia caused by obstruction, and the degree of uremia is reflected in the degree of decrease in hemoglobin. In case of urinary tract infection, blood leukocyte count and classification are also of reference value for diagnosis and treatment.
3, kidney function measurement.
Patients with prostatic hypertrophy can select 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) Determination of serum prostate-specific antigen (PSA) PSA.
This method 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 examination.
Changes in urine flow rate can indirectly measure the function of the lower urinary tract, which is very helpful in determining 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.
In normal people, the residual urine is not greater than 10 m1, while patients with prostatic hypertrophy may experience an increase in the amount of residual urine, so the determination of residual urine is one of the important diagnostic steps. 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 way to detect this is by transabdominal ultrasound. Since there are large fluctuations in the amount of residual urine in a person, the initial examination should be repeated once for accuracy if there is a large amount of residual urine.
7. Zinc determination.
Plasma zinc levels are significantly higher in the case of prostate hypertrophy. It can be used as one of the indicators for the diagnosis of prostate hypertrophy.
