Gallstone complications may be detected on blood tests. [2] On abdominal ultrasound, sinking gallstones usually have posterior acoustic shadowing. In floating gallstones, reverberation echoes (or comet-tail artifact) is seen instead in a clinical condition called adenomyomatosis. Another sign is wall-echo-shadow (WES) triad (or double-arc ...
Gallstones can get trapped in the gastrointestinal tract, most commonly at the connection between the small and large intestines (ileocecal valve). When a gallstone gets trapped, it can lead to an intestinal obstruction , called gallstone ileus , leading to abdominal pain, vomiting, constipation , and abdominal distension .
It is not possible for the kidneys to produce urine with a specific gravity greater than 1.040 [40] but such readings can occur in urine that contains high-molecular weight substances, such as contrast dyes used in radiographic imaging. [38] Specific gravity is commonly measured with urine test strips, but refractometers may also be used. [41]
A laser can be used to split big stones and make it easier to solve it using laparoscopy. [4] If the either of these procedures is unsuccessful, the stone can be removed during surgery through an incision into the bile duct at the location of the stone (called choledocholithotomy).

Gallbladder diseases are diseases involving the gallbladder and is closely linked to biliary disease, with the most common cause being gallstones (cholelithiasis). [1] [2]The gallbladder is designed to aid in the digestion of fats by concentrating and storing the bile made in the liver and transferring it through the biliary tract to the digestive system through bile ducts that connect the ...
Biliary colic, also known as symptomatic cholelithiasis, a gallbladder attack or gallstone attack, is when a colic (sudden pain) occurs due to a gallstone temporarily blocking the cystic duct. [1] Typically, the pain is in the right upper part of the abdomen, and can be severe. [2] Pain usually lasts from 15 minutes to a few hours. [1]
A random urine, meaning a specimen that is collected at any time, can be used for many tests. However, a sample collected during the first urination of the morning (first morning specimen) is preferred for tests like urinalysis and pregnancy screening because it is typically more concentrated, making the test more sensitive .
