Prostatic hyperplasia do urine routine can not clarify the disease, urine routine examination can only assist in determining whether there is secondary infection, stones and other abnormalities. Prostatic hyperplasia can take physical examination, mainly for rectal examination, in order to initially determine whether the patient has prostate cancer and neurogenic bladder dysfunction. This examination is the more important examination method of prostate hyperplasia, and all patients with this disease need to do this examination. Transrectal ultrasound or transabdominal urologic ultrasound can also be done to evaluate the size of the prostate, the echogenicity of the central and peripheral bands of the prostate, to determine whether there is the possibility of prostatic hyperplasia. In addition, tests such as prostate symptom scoring and prostate-specific antigen may be done. In some patients, further urologic specialty testing is required, including uroflowmetry, filling cystometry, urethral manometry, bladder work capacity measurement, simultaneous external urethral sphincter electromyography and bladder pressure electromyography, and leak point pressure measurement. When prostate enlargement occurs, it is recommended to seek medical attention, follow the doctor’s instructions for further examination, and manage or treat it after the doctor’s comprehensive consideration.
