Solitary cysts of the kidney: symptoms, treatment and prevention

Cysts are referred to as benign formations,which contain the liquid inside. They can be found in most human organs. In appearance, a safe education can sometimes become dangerous, reborn into cancer.

For this reason, doctors keep such patients understrict control. Cysts respond to treatment, and if this does not happen, they are removed surgically. 10% of the total population have solidarity cysts in medical practice. Consider the features of such formations.

Characteristics of the disease

In modern medicine, a cyst is called anyA cavity that has walls of relatively healthy cells. Its dimensions may be different. For benign renal formations it is characteristic to have different sizes - from a few millimeters to several centimeters. The site of localization is the upper or lower part of the renal segment.

The term "solitary" means singlecysts. Solitary cysts of the kidneys are also called simple. Their shape is round, sometimes elongated (resembling an oval). Such formations do not have joints or constrictions. Inside is a serous fluid.

The disease affects men more often. Basically, there is a solitary cyst of the left kidney, rarely a right one. It is easily diagnosed with ultrasound.

cyst of the kidney solitary


Simple kidney cysts are divided into:

  • congenital;
  • acquired.

Depending on the location of the kidney cyst, the solitary can be:

  • cortical (located in the cortical layer);
  • subcapsular (located under the capsule of the organ);
  • intraparenchymal (located in the thickness of the organ tissue);
  • sinus (located close to the pelvis, but not connected to it);
  • multilocular (has many chambers, but this kind of cyst is rare enough).

Principle of development

Acquired and congenital cysts have the samemechanism of development: the basis is the obstruction of the tubule, which leads to its stretching. If we talk about congenital pathology, then there may be a disruption in the relationship between the tubules that form during the development of the fetus in utero. Acquired cyst develops due to a violation of the outflow of urine along the tubule. This disorder is provoked by various diseases that a person can tolerate throughout life.


Medical science, although it does not stand still, is not yet exactly ready to answer the question: "Why are solitary cysts of the kidneys formed?" There are only assumptions from which they are repelled.

One of the reasons is a congenital anomaly. Even in the period of intrauterine development, there are some violations in the formation of ureters and kidneys, which provoke the formation of a simple cyst.

If we talk about the acquired cyst, the main reasons for its appearance are:

  • any injuries of the kidneys;
  • violation of the outflow of urine due to urolithiasis (concrements do not allow urine to normally exit);
  • infectious diseases of the kidneys (some of them are secretive, without causing any suspicious symptoms).

Stagnation of urine for any reason leads to stretching the walls of the kidney, resulting in the formation of cysts. They can develop quickly, but the person does not feel anything at all.


Often the cyst of the renal solitary cyst developsasymptomatic for many years. It is discovered by chance, when a person is doing ultrasound of internal organs. If signs already appear, then in such cases, inflammation of the kidneys and at the same time formed cyst. Symptoms depend on the size of the cyst, as well as the concomitant diseases.
