In order to achieve the results of an ultrasound, some people need to produce urine as soon as possible before the ultrasound is performed, thus filling the bladder. The usual choice is to promote urine production by drinking water, followed by urine holding. Because in the process of walking gastrointestinal peristalsis accelerated, resulting in rapid absorption of water, metabolism into the bladder, the formation of urine, can be faster to fill the bladder, easy to ultrasound examination, so compared to sitting to promote urine, walking to promote urine is more effective. If you need to hold your urine for the examination, drinking water and then repeatedly walking around will improve the efficiency of the digestive system, thus speeding up the conversion of water into urine and helping the urine to be stored in the bladder more quickly. In addition, the examinee can not only urge urine by walking before ultrasound, without diabetes mention, moderate consumption of sugar water, can assist in increasing the osmotic pressure of the renal tubules, in order to achieve the purpose of rapid filling of the bladder. However, patients with hyperglycemia, as well as diabetics, are strictly prohibited from using this method.
