In Tibetan Buddhism, blue is the color of Vairochana, a celestial Buddha, whose image is the immensity of sky blue.

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 (also known as renal lithiasis) are hardened material found inside the kidneys, and are made of crystallized minerals and salts. They can occur anywhere along the urinary tract, between the kidney and bladder, and vary in shape and size - some are as large as a golf ball.
