Urine is formed in the kidneys, specifically by the renal tubules in the nephrons of the kidneys. It then is collected by the renal pelvis, where it exits though the ureters, moves to the bladder where it is stored until urination, during which it is expelled through the urethra.
Urolithiasis (from Greek ouron,  oÃ»ron , + urine, lithos, + -stone) iasis is the formation of urinary (calculi urinary), stones which are calculi formed or located anywhere in the urinary. systemidney stones typically leave the body by passage in the urine stream, and many stones are formed and passed without causing symptoms. If stones grow to sufficient size (usually at least 3 millimeters (0.12 in)) they can cause obstruction of the ureter.
