Kidney Cyst Symptoms

The decisive factor in the manifestation of symptoms of the disease in question can be described inherent size. The initial stage of development of cysts is characterized by small size of it because the disease is generally characterized by the absence of any specific symptoms.

Meanwhile, the gradual growth of tumors causes pressure on the renal pelvis or ureter. It was then that the first symptoms appear and kidney cysts. Among those can be designated appearance feelings of gravity centered in the lower back, as there may be aching in the area. Generally pain is characterized by precise localization of the side which struck the kidney, that is where the cyst is located.

When the cyst becomes large enough, it can break down the outflow of urine from the kidney, because of which, in turn, there is fluid retention. This phenomenon is a predisposing factor for accession to the pathological process of secondary infection. Under this option, the clinical picture is accompanied by symptoms of fever, weakness, chills, severe pain in the lumbar region (with their spread to the genitals). Urine in this case is changed, becoming cloudy.

Remarkably, the infection of which the above question begins to grow not only in the body of strikes, that is, in the kidney, but also directly into the cyst. Such flow is accompanied by a characteristic picture of the abscess, which is also accompanied by severe pain in the lower back from injury and fever. Suppuration inflamed cysts or rupture is accompanied by symptoms characteristic of acute abdomen. This implies a pronounced tension in the muscles at the front of the abdominal wall, as well as the presence of pain, which is celebrated not only in the lumbar region, but also in the stomach.

Long-term course of the disease may be characterized by the manifestation of the picture that accompanies chronic renal failure. In this case, characteristic is the increase in the total amount of urine and complete its subsequent disappearance. Also, concomitant symptoms is the presence of blood in the urine, high blood pressure.

Kidney Cyst: Complications

The most common possible complications of kidney cysts release her break. It can lead to even minor impact on nature. This is accompanied by the spout cyst contents directly into the abdominal cavity, which is why it cavity becomes inflamed (developing peritonitis). Peritonitis is a very serious condition that may require surgery.

In addition to breaking abscess may also develop cysts, which is accompanied by weakness, acute back pain and temperature. This condition also requires surgery followed by antibiotic therapy.

If a cyst in size becomes large enough, the violation shall be on a background of compression of vascular structures of the kidney. Operation in this case it is broken, in addition to this developing uremia – self-poisoning of the body as a result of actual renal failure (kidney infected blood toxins). Basically, the option of developing the disease is typical for bilateral disease process, although it is not ruled out, and in the defeat of only one kidney.

And finally, as a complication can be designated the possibility of malignancy of the pathological process, ie its transformation from a benign process in the malignant process.


In the diagnosis of renal cyst apply traditional methods of diagnosis. In particular, this ultrasound, CT and MRI – based on the results of these diagnostic methods are available a detailed and accurate picture of the structure and characteristics of the cysts of their location.

Besides applied radioisotope study of renal function, based on which can be confirmed (or, alternatively, excluded) nature of the process, it is possible to determine the process is benign or malignant. Such methods include Doppler ultrasound, urography, angiography and scintigraphy.

In addition to these diagnostic methods are also shown blood (biochemistry and general) and urinalysis.


The most common way to treat the cyst is expectant management, in which the foundation becomes the dynamic control of the state of the cyst. Such control allows time to determine when the cyst begins to grow, which already requires the appropriate surgery. In turn, the latter measure effects on cyst, an operation performed when the cyst has become a hindrance to the proper functioning of the affected organ.

Turning to the surgical intervention as a way to treat cysts can indicate that there is made of the removal of the cyst capsule. If the cyst is formed deep in the renal parenchyma, it may be necessary in deciding whether to remove a cyst, together with the affected kidney. It is also an indication for surgery are the following features of the patient:

  • severe pain;
  • a significant impairment of the function of the kidneys;
  • a cyst in size greater than 40-45 mm;
  • the patient on the basis of the relevance of the tumors are concerned high blood pressure, are not eliminated by the action of the relevant medicines;
  • to relevant parasitic disease etiology;
  • There are signs malingizatsii cysts (noted earlier malignancy process).

In addition to surgical intervention treatment of kidney cysts also requires implementation of conservative methods, that is in particular the need for pain medication and antibiotics within the postoperative period.

Treatment of renal cyst folk remedies would like to designate separately. It is important to understand that such treatment is not only ineffective in combating the disease before us, but also may be dangerous (depending on the degree of damage, type and stage of cysts actual pathological process, and other features related to the pathological process). In addition to the lack of any positive results of such treatment can not only cause loss of time in the wrong treatment of the patient, but on the other hand, due to excessive exposure to the active treatment methods used can be triggered by a cyst rupture. As already indicated, in this case, the contents will be poured into the abdominal cavity that trigger peritonitis, in which already without urgent surgical intervention, and even more serious consequences can not do. The maximum that can be used from a number of measures – some herbal teas.

Regardless of the options of the measures it is also important to make some adjustments to your lifestyle. In particular, it is necessary to reduce the amount of salt intake in the diet foods, salty foods. It should also monitor the volume of fluid intake, especially if there is a tendency to a progressive swelling. Restrictions also apply to the consumption of protein foods, subject to the exclusion of coffee and related products, which include cocoa, seafood, sea fish. A special place is a need for rejection of alcohol and smoking.

The forecast for kidney cyst can comply with the following options:

  • Identify the patient’s innate forms multiobrazovany (multiple cysts of one type or another) with damage to both kidneys determines a poor prognosis for him, moreover, in the case of kidney cysts are incompatible with life.
  • If any congenital forms of autosomal recessive formations and unfavorable prognosis. In this case, babies are very rarely survive to the age of two months.

Positive almost 100% prognosis is for a simple renal cyst, and this option is relevant regardless of implemented treatment strategies (surgery or conservative therapy).
