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 are a common disorder of the urinary tract. Kidney stones are pieces of stone-like material that form on the walls of the kidney. They are caused by a buildup of minerals in urine. Most stones are so small that they pass through the urinary system without pain. However, a large enough stone can cause extreme pain or urinary blockage. This is very painful, and requires treatment or surgery. In the United States, about 1 million people get kidney stones every year.
