The urinary system, with kidneys as the major organ, is responsible for elimination of toxic waste from the body and thus also maintaining the chemicals-water balance. Sometimes, more often in men than in women, the excess salts and minerals like calcium, sodium, phosphate, etc. become solidified and formed into stone-like, hard, crystaline structures. Such stone disease is one of the most prevalent urological disorders.The conditions of stones in the ureters or urinary tract are known as Ureterolithiasis.
Urinary Stones may be Kidney Stones, Bladder Stones or Ureteric Stones.
