A kidney stone (yellow) composed of calcium oxalate, next to a tourmaline gemstone for scale. Calcium is one component of the most common type of human kidney stones, calcium oxalate. Some studies suggest that people who take calcium or vitamin D as a dietary supplement have a higher risk of developing kidney stones.
The bile duct is some 6–8 cm long, and normally up to 8 mm in diameter. [4]Its proximal supraduodenal part is situated within the free edge of the lesser omentum.Its middle retroduodenal part is oriented inferiorly and right-ward, and is situated posterior to the first part of the duodenum, and anterior to the inferior vena cava.
The human gallbladder is a hollow grey-blue organ that sits in a shallow depression below the right lobe of the liver. [2] In adults, the gallbladder measures approximately 7 to 10 centimetres (2.8 to 3.9 inches) in length and 4 centimetres (1.6 in) in diameter when fully distended. [3]
Extraction of choledocholithiasis and/or intrahepatic stones: choledocholithiasis is the presence of gallstones within the common bile duct. They can be either primary (formed within the duct) or secondary (entering the duct from the gallbladder). Biliary endoscopic sphincterotomy allows for opening of the sphincter of Oddi, allowing stones to ...
Crohn's disease that affects the ileum may result in an increased risk of gallstones. This is due to a decrease in bile acid resorption in the ileum, resulting in bile excretion n the stool. As a result, the cholesterol/bile ratio increases in the gallbladder, resulting in an increased risk for gallstones. [55]
The gallbladder is a hollow part of the biliary tract that sits just beneath the liver, with the gallbladder body resting in a small depression. [26] It is a small organ where the bile produced by the liver is stored, before being released into the small intestine.
This stage accounts for 17% of kidney cancers and 69% of people are expected to live 5 years with this progression of kidney cancer. •Stage 4, the kidney tumour has spread to a distant organ or lymph node. 16% of kidney cancers are progressed to this stage and of those people, 12% of them are expected to live 5 years.

Duodenum: A short structure (about 20–25 cm long [18]) that receives chyme from the stomach, together with pancreatic juice containing digestive enzymes and bile from the gall bladder. The digestive enzymes break down proteins, and bile emulsifies fats into micelles .
