Oxaluria (Oxaluria)

Oxaluria is the presence of oxalic acid or oxalates, in particular calcium oxalate, in the urine. Excretion of large amounts of oxalates from the body in the urine is observed with oxalosis.

Oxaluria can be primary or secondary. Primary oxaluria is caused by impaired oxalic acid metabolism due to congenital defects of enzymes or transporters. Secondary oxaluria occurs with an increased intake of oxalates from food, impaired absorption in the intestine, hyperabsorption in the small intestine.

The main causes of oxaluria are:

  1. Primary hyperoxaluria is a hereditary disorder of oxalic acid metabolism.

  2. Secondary hyperoxaluria is excessive consumption of oxalate-containing foods, impaired absorption of fats and fat-soluble vitamins.

  3. Enteral hyperoxaluria is increased absorption of oxalates in the intestine due to various diseases.

Main symptoms: lower back pain, hematuria, pyuria, nephrolithiasis, renal failure.

Diagnosis is based on urine analysis and determination of daily oxalate excretion.

Treatment consists of normalizing oxalate metabolism, an oxalate-restricted diet, the use of fat-soluble vitamins, and surgical removal of stones.



Oxaluria is a condition in which excess amounts of oxalic acid, or oxalates, are found in the urine. Oxalates are one of the most common types of oxaluria, and can be caused by a variety of factors, including genetic disorders, dietary factors, and certain medications.

One of the most well-known conditions associated with oxaluria is oxalosis. With oxalosis in the body, oxalates accumulate in the kidneys and other organs. This can lead to the formation of kidney stones, which can cause pain and discomfort for the patient.

Another common condition associated with oxaluria is nephrolithiasis. With nephrolithiasis, stones are formed in the kidneys, consisting of calcium oxalate, which is one of the main components of oxalates. These stones can cause pain, difficulty urinating, and other symptoms.

In case of oxaluria, you should consult a doctor for diagnosis and treatment. Treatment may include diet changes, medications, and removal of kidney stones. If oxaluria is caused by a genetic disorder, ongoing treatment may be required.



Oxaluria is a special disease that is characterized by the release of a high content of oxalate stones from urine. The pathogenesis of the disease is directly related to metabolic disorders and lack of health of the internal environment. Deficiency concerns calcium and phosphorus, as well as iron. Iron depletion is manifested by hemoglobin deficiency and the development of anemia. A lack of vitamin D leads to a decrease in calciferol levels, which negatively affects phosphorus metabolism. The presence of calcium in the urine in concentrated form causes a crystallization process, which leads to the appearance of oxalate stones.
