A father with nocturnal polyuria can have a routine urine test and urinary ultrasound (to measure residual urine). If necessary, more in-depth, systematic and comprehensive investigations such as X-rays, CT, serological PSA tests, etc. need to be performed under medical supervision.
This is one of the three basic tests that can help the doctor to get a basic picture of the patient and make a preliminary diagnosis of urinary tract disease and kidney disease. If no abnormal results are seen in the routine urine examination, a rectal examination or urological ultrasound can be performed to determine the size of the prostate gland. The prostate is a uniquely male organ that can undergo degenerative changes such as hyperplasia with age, which can compress the urethra and bladder and induce symptoms of nocturnal enuresis.
If there are still no abnormal findings, the possibility of other systemic diseases needs to be considered and CT, X-rays, serology and other tests are selectively performed depending on the specific situation.
