Oxalate stones in the kidneys: how are they formed, is it possible to dissolve, how to remove

Among all the stone formations in the kidney tissues, oxalate stones are most often formed, accounting for about 70% of cases. Independently dissolve such stones are almost incapable, so often they grow to an incredible size, which explains their danger to patients.

Oxalatite stones in the kidneys

Calcium oxalate salts form the basis of oxalate stones. Such stones are distinguished by a dark brown or black shade and an uneven surface with sharp outgrowths, which can easily damage the inner membranes of the urinary structures. Therefore, these concrements are usually treated operatively, as they often cause painful discomfort, kidney colic and dangerous complications.

Concrements of oxalate origin are typical for young patients. They are easily detected with ultrasound diagnosis.

Reasons for

Oxalate stone formation begins with the appearance of oxalaturia, when oxalate crystals appear in urine. The components of oxalic acid react with calcium from which oxalate crystals are formed. N

ormally, when the body is healthy, these crystals are safely excreted from the body, without catching the walls of the urinary organs. But if the patient suffers from inflammatory pathologies, or his urine is overly concentrated, then the oxalate crystals penetrate the cup system of the kidneys, where they transform into oxalate plaques and then into the calculi.

In addition, one can not exclude such reasons for education:

  • Frequent psychoemotional problems;
  • Pathology of the Crohn;
  • Deficiency of vitamins B against a background of excessive content of ascorbic acid;
  • Magnesium deficiency;
  • Columns of various types;
  • Various complications, provoked by advanced genitourinary pathologies;
  • Pyelonephritis and pyelitis;
  • Hereditary predisposition;
  • Operative interventions on the gastrointestinal tract;
  • Diabetes sugar.

Oxalatite stones are found in about 5% of the entire population of a predominantly young age. They are dangerous because they can injure the urinary structures, which leads to serious bleeding. Patients can determine bleeding by the characteristic impurities in urine. It is because of the bleeding that the oxalate concretes acquire such a characteristic brownish-black hue.


Usually, oxalate stones appear as formations of various shapes with spiny outgrowths. The color of the stones is black or brown. Uneven surfaces and solid structures cause deformation and damage to the internal tissues of the urogenital system, which leads to bleeding, which seriously complicates the course of the pathological process. By the color of the calculus, you can determine how often he provoked bleeding complications. If the stone did not cause any damage, then the color of the stone will be light.

Dimensions of oxalate stones can be quite small in size a few millimeters or large - more than 4 cm. The presence of adverse factors like a deficiency of fluid or pyelonephritis can provoke the degeneration of oxalate crystals into coral-like stones that fill the entire kidney. Quite often, other salts are added to the oxalate base, then the stone in the section will have a layered structure.

In children up to the age of five, oxalate stone formation is often asymptomatic. Although the occurrence of acute painful attacks caused by renal colic is not ruled out.


The simplest diagnostic technique is a general laboratory study of urine. Usually, its results are sufficient to detect urolithiasis and to determine the chemical structure of calculi.

As additional diagnostic procedures are:

  • Contrast urography;
  • Renal scanning;
  • Ultrasound diagnosis;
  • Radiography;
  • Bakpoev urines;
  • Chromocytoscopy.

Such activities help to clarify the necessary features of the structure of stones, dispel some doubts about the diagnosis, etc.

Treatment of

Treatment of oxalate kidney stones Therapy of oxalate stones is complicated by a dense structure of pebbles, which is why it is not always possible to fragment them, as well as dissolution. If the concrements are large, then you can get rid of them only in an operative way. This is the answer to the question whether it is possible to independently remove the stones.

Therapy is performed in several stages:

  • Medical treatment with the use of specialized drugs that remove stones and restore the real exchange processes.
  • Physical activity is necessary, with regular training, the excretion of stones from the kidneys is activated, especially jumping and running are particularly useful.
  • Increased drinking regimen. With the help of water, active purification of organic structures takes place, oxalate stones begin to depart. For effective withdrawal you need to drink at least 2 liters of fluid.

Surgical intervention

Surgical treatment of oxalate kidney stones Surgical removal of oxalate stones can be performed by means of a classical open band surgery or endoscopically. At small sizes of stones the technique of ultrasonic crushing is applied, after that stones are deduced in the form of sand.

If during the diagnostic examination only sand and oxalate microliths were detected, then a complex treatment is designed to dissolve the stones and to remove sand from the genitourinary structures. In addition, prevention is necessary to avoid re-accumulation of calculi in the kidneys.
