There are many urology examinations. Generally speaking, if you are doing color Doppler ultrasound, urine routine test, urine sediment, CT and other examinations of the urinary system, you often do not need to fast, but you need to hold urine.
But there are also some special examinations that require fasting, so that the results will be more accurate. For example, intravenous urography examination, since the contrast is to be examined under X-ray, if the patient eats before the examination, there will be more gas or food residue in the intestine during the examination, which is easy to affect the imaging effect of the contrast.
In addition, renal function tests also require fasting blood collection, because it contains some electrolyte tests, and eating can easily affect the accuracy of electrolyte results.
In short, when patients need to do some urology examinations, they must go to a regular hospital for treatment, under the guidance of professional doctors, follow the doctor's advice to prepare for the examination to ensure the accuracy of the examination results.
