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.
