Types of Kidney Stones

Kidney stones can cause serious problems within the body if they do not pass naturally (via urine) or if not removed.

Kidney stones are common and can be found in one in every 25 people. The types of kidney stones are:

  • Struvite: Women are more susceptible to these types of stones because they suffer more from urinary tract infections. Infections of the urine can easily cause struvite stones to form in the body.
  • Uric acid: These stones are common among patients with gout or people that undergo chemotherapy. These types of stones begin to form when there is too much acid in the body. Uric acid stones are more common among men than women.
  • Cystine: This is the rarest form of kidney stones and usually occurs in those who suffer from cystinuria. Leaking acid in the body that travels to the urine is the main cause of these stones.
