Knowledge Point

1.Which tests require fasting and which require holding in urine?

Organ examinations require fasting: liver, gallbladder, pancreas, spleen, renal blood vessels, abdominal aorta, etc. Because on the one hand, food will cause the gallbladder to contract and empty bile, the structure and shape of the gallbladder will be affected by ultrasound after the gallbladder contracts. On the other hand, the abdominal contents and gastric gas after eating will be affected, and some ultrasound sections will not show clearly. It is easy to misdiagnose or miss the diagnosis and delay the condition.

2.Is ultrasound harmful to the body?

The medium used in ultrasonic examination is ultrasonic wave, which has no ionizing radiation. The conduction in the human body uses the characteristics of sound waves, just like the sound of our speech. Ultrasound examination is a very safe examination and is therefore commonly used in obstetrics to examine the fetus.

Why do some ultrasound examinations require holding back urine? How much is appropriate to hold in?​

Before conducting urinary system examinations such as bladder, ureter, and prostate, as well as gynecological ultrasound examinations in unmarried women, patients with heavy vaginal bleeding, and patients in the first three months of pregnancy, it is necessary to hold back urine and fill the bladder appropriately to reduce intestinal gas interference and provide good Acoustic window. For gynecological ultrasound, the bladder urine volume is required to be 300-400ml. As far as experience is concerned, drinking 500-800ml of water before the examination generally requires holding in urine for 2 hours, and drinking 800-1000ml of water requires holding in urine for about 1 hour. A good sign of a full bladder is that the lower abdomen bulges in a shallow arc when lying down, and can be pressed down and held back when pressure is applied.
