kidney puncture - to be or not to be?

As you know, according to statistics research one in four people aged over 42 years found one or more kidney cysts that are larger than 10 mm.And the incidence of the disease is greater the older the person, there is not only less than the eight out of a hundred of people with this disease must be treated seriously.

need for all sorts of medical procedures arises only when the patient has a complaint:

  1. pain or discomfort in the kidney projection;
  2. to change the nature of urine or problems with urination;
  3. on blood pressure.

also an occasion to treat kidney cyst is a seriously large size cysts (50 mm or more) and the presence of other diseases of the body, such as pyelonephritis or urolithiasis.If not the above complaints, and she kidney cyst does not exceed 50 mm, such that the patient is recommended to periodically once or twice a year to perform ultrasound of the kidneys to control the growth and stability of the bulk of education sizes.

Today with medical-diagnostic purposes the most successful

method is a minimally invasive percutaneous renal puncture.In some cases, laparoscopic surgery or open access can be performed when indicated.

What puncture the kidney cysts?

kidney cyst puncture - a medical manipulation, which involves the formation of a puncture, aspiration of the liquid contents of it, which is then sent for examination, and often the introduction of sclerosant.This procedure is performed using a special needle under the control of ultrasound or x-ray visualization of the body.

This is important! kidney cyst puncture with aspiration of its contents in more than half of the cases in a short time led to its re-emergence.Since this was only part of the solution: the content was removed, and the walls lined with cells secrete liquid remained, which is responsible for the development of relapse.At the moment, the problem of refilling once drained the cyst disappeared, thanks to the use of the method sclerosing cavity.

cavity scarring during puncture the kidney is performed by introducing pure ethanol (96%) in the amount of about a quarter of the volume of extracted liquid is also applied to the combination of alcohol antibiotics or antiseptics, 7-15 minutes of drug is aspirated cysts.

This is important! Some experts recommend a longer exposure time sclerosant (up to 2 hours).Also, according to research by several authors hold 12 hours to re-puncture the kidney with the introduction of the ethanol or other sclerosing agent gives a much more pronounced effect and reduces the likelihood of cyst recurrence.

How is kidney puncture?

kidney cyst puncture procedure is performed under local anesthesia and takes on the whole a little more than half an hour.The patient is asked to lie down on the healthy side or on your stomach, place next puncture treated with antiseptic and anesthetic drug cut away.Ad Hoc puncture needle pierced the skin and underlying tissues, and then it is under the control of the ultrasonic apparatus (X-ray installation) is inserted into the cyst and through the extracted contents of the cavity.Typically, the liquid obtained in the course of kidney puncture, has a straw yellow hue, but if the cyst has degenerated into a malignant tumor, punctate may take on a reddish or brown.

Some of the resulting liquid is sent to the cytological and biochemical studies.After emptying its cyst wall fallen down and is injected into the cavity of the contrast agent to check: whether it communicates with cups or renal pelvis.In the case where the cavity is isolated from the other kidney structures carried sclerosing administering drugs.

Contraindications to puncture

In some cases, the implementation of a kidney puncture can not be performed due to the presence of contraindications:

  1. Multiple or multi-chambered cyst - to achieve a positive result from puncture the kidney is necessary to remove the content and sclerosed all cysts or all cameras oneeducation, but that during this process of renal disease is difficult to produce the required volume;
  2. calcification or sclerosis cyst wall - for sealing the shell after removal of the cystic liquid is not fallen down, so holding the puncture in this case is not effective;
  3. Parapelvikalnoe location cysts - at such localization education percutaneous access to it is difficult;
  4. cyst, communicating with the cavity system of the kidneys - the introduction of sclerosing agents is not possible, in view of the fact that they are spread on the abdominal system, damaging it;
  5. its diameter exceeds 75-80 mm - with such dimensions, the probability of its recurrence after puncture is very high.

This is important! The larger cysts, the lower the efficiency of the sclerotherapy.This statement applies to entities whose diameter exceeded 7 centimeters.

In these cases, a puncture with the introduction of the ethanol can be inefficient or not available due to the localization of education, therefore, carried out alternative methods of treatment such as surgery or laparoscopic removal through open access.

Possible consequences of kidney puncture

kidney puncture - a procedure that is performed on an outpatient basis, and in most cases does not require inpatient monitoring.The consequences of puncture are rare, as the ability of modern ultrasound machines allow to avoid most probable errors during manipulation, such as damage to the large blood vessels and / or renal pelvis renal system.

probability of infectious complications of this procedure is also low, because after the puncture, the patient is assigned to receive prophylactic antimicrobials.

Sometimes patients may observe such effects puncture the kidney as nausea, fever, appearance of hematomas at the puncture site, redness of the urine, but usually all these phenomena are short-lived and do not require specific treatment.

This is important! Following the puncture and cyst sclerotherapy likelihood of full recovery of 74-100%, if the same procedure was performed twice (the second 12 hours after the first one), this figure reaches 94%.
