Enlargement of the prostate gland is most often seen in prostate enlargement, and the severity of the condition is not consistent with the degree of enlargement of the prostate gland. It is not possible to determine the severity of the disease by the degree of enlargement of the prostate. For the short-term obvious enlargement of the prostate, or uneven enlargement of the prostate, the possibility of prostate tumor should also be considered. When the prostate is found to be enlarged, ultrasonography of the prostate, blood test for PSA, etc., and prostate puncture biopsy if necessary, can distinguish benign prostatic hyperplasia from prostate tumor. The condition of prostate tumor depends on the pathological type and stage of the tumor, which is not directly related to the enlargement of the prostate. Once the prostate tumor is found, it should be actively treated by surgery. The degree of prostate hyperplasia depends on the degree of obstruction, the speed of development of the lesion and whether it is combined with infection. The International Prostate Symptom Scale, which is used to determine the severity of prostate enlargement symptoms, is as follows; Has the following symptoms occurred in the last month: 1. a frequent feeling of not being able to urinate; 2. frequent intervals between urination on both sides of the body of less than two hours; 3. a history of intermittent urination; 4. a phenomenon of not being able to wait to urinate; 5. a phenomenon of a thinning of the urinary line; 6. the need to exert oneself in order to begin to urinate; and 7. the need to urinate several times from the time you go to sleep until you wake up in the morning. The scale can be used to determine the degree of prostate enlargement. It is important to note that the scale should be completed under the supervision of a medical professional. In addition, rectal examination and ultrasonography can also be used to clarify the condition.
