In Tibetan Buddhism, blue is the color of Vairochana, a celestial Buddha, whose image is the immensity of sky blue. [2] Buddhist monks wear orange (specifically the color saffron) robes primarily due to tradition. That was the least expensive color dye at the time and that is what they continued to wear.
Choledocholithotomy, or common bile duct exploration, is used to remove large stones or in cases when the duct anatomy is complex. In this procedure, the doctor carries out open abdominal surgery and extracts gallstones through an incision in the common bile duct.
Kidney stones (calculi), stone-like crystals of differing sizes and shapes, can develop in one or both of the kidneys. Medically known as nephrolithiasis, kidney stones can block the flow of urine and in extreme cases result in a kidney failure. These occur when salts present in the urine form a solid lump or stone. Most kidney stones do not require surgery and are passed out of the body painlessly when you urinate.
