The Overview of Kidney Cyst

The general understanding of kidney cyst

In literally, in the two side of kidney, there have some cyst which is not connected with the outside world of cystic masses and filled with the liquid.

kidney cyst is a kind of kidney disease. In clinical, kidney cyst can be divided into two types, namely Polycystic Kidney Disease and simple cyst. So is kidney cyst serious? Let’s look at the classification and hazard evaluation of the renal cyst.

Polycystic kidney disease (PKD) contains the three types, that’s the type of infantilism, children and adult. Adult polycystic kidney is a congenital genetic disease. If any party of parents has PKD, there is 50% probability for their child to carry this disease.

Cyst will enlarge as time goes on. The increasing cyst not only pull renal capsular causing lumbar unwell, but also oppress kidney and affect the renal function.

The simple cyst especially adult cyst is common in the clinical. Its’ pathogenetic mechanism has a close relationship with renal tubular obstruction ischemia and congenital developmental disorders. Simple cyst is divided into single cyst and multiple cysts, both of them have different prognosis.

If you are unlucky to be diagnosed with kidney cyst, a comprehensive examination to seek a suitable treatment and cooperate with relevant professional treatment are important for treating renal disease.

2.Gene mutation

For polycystic kidney disease, mostly caused by their parents' genetic. It’s divided into autosomal dominant and autosomal recessive. But some polycystic kidney patients is neither parents genetic, also do not belong to the developmental defect and benign polycystic kidney disease. It belongs to embryos formed of mutations.


Toxins affect on the human body, which can cause a severe damage to the all kinds of tissue organs. Thus, it can lead to some life-threatening diseases. The common toxins can be seen in the pesticides, certain chemicals, radiation, pollution and so on.

IVP( Intravenous pyelography). It can shows the degree of cysts’ oppression and can identify with hydronephrosis.

Further check

CT check. When cyst occurs with infections, bleeding and canceration, the CT value will increase.

The different sizes of cyst

Cyst will grow along with the increase of age. Your cyst can be checked by Ultrasound B. If the cyst grows slowly or hardly developes, there is no need to treat it. But if the cyst has a fast growth rate, you should take a medical treatment to prevent the growth of cyst.

What’s the effective treatment for kidney cyst?

In general, when the kidney cyst approaches to 4 cm, patients need to treat it actively. Otherwise the long-term oppression of cyst will cause nephron ischemia and hypoxia, and then lead to high blood pressure or other complications.

The traditional treatment adopts Cyst Unroofing Decompression and Puncture Hardening. But after the kidney cysts are reduced, they will grow quickly with the help of pressure action. Kidney cyst can relapse over and over again.

Micro-Chinese Medicine Osmotherpay is different. The core technic of this therapy is to block renal fibrosis and improve kidney function. By activating blood and dilating blood vessels, improving the whole body’s blood circulation, reversing the cyst fluid and intravascular fluid pressure around the cyst, to make the liquid inside of the capsule be taken away along with blood.

At the same time, due to the extending of blood vessel, capsule wall cell metabolism function will recover and thus reduce the production of sac liquid.

The function of extending blood vessels can shrink cysts. After that, the kidney oppression around the renal tissue will relieve and disappear.

Aside from extending blood vessels, micro-Chinese medicine osmotherapy also has other functions like anti-inflammation, anti-coagulation, degradation, repairing the damaged intrinsic cells and renal function, rebuilding the internal renal structure.

Through a period of treatment, the renal function can get a great improvement. Hence, treating kidney cyst is not a difficulty.
