Why is urine routine color Doppler ultrasound normal and frequent urination?

Normal urine routine color Doppler ultrasound may also be caused by excessive drinking water, bladder dysfunction, prostate hyperplasia and other reasons. Details are as follows:

1. Drinking too

much water in a short period of time easily leads to increased blood volume, and then blood filtration through the kidneys increases, resulting in increased urine, resulting in frequent micturition.

2. Bladder dysfunction When

urine is stored normally, 200-300mL will stimulate the bladder nerve to produce micturition sensation, but for patients with overactive bladder, when urine is stored for 50-100mL, it may stimulate the bladder nerve to produce micturition sensation, resulting in frequent micturition. At this time, urine routine is normal.

3. Prostate

hyperplasia can compress the prostate urethra or bladder urethral orifice, causing bladder obstruction and urethral lengthening, thus causing frequent micturition symptoms.
