What is Renal Cortical Cysts?

Renal Cortical Cyst is one kind of simple kidney cysts that are in the renal cortical areas and it is one of the most common kidney diseases.

The exact causes of the renal cortical cysts has not be found out until now and it may be merely due to aging since the renal cortical cysts are very common among people that are over their 50s and the incidence of the disease will increase along with the age. Though the causes of the renal cortical cysts remain unknown, it is confirmed that some certain factors will cause the rapid growth of the cysts and cause substantial damages to the kidneys and involve many other organs in the end stages.

There may be one or several cysts in the renal cortical areas and the cysts can grow gradually and in some cases the cysts can be larger than 10cm and the patients can sense obvious lump in their belly. In such conditions, the cysts are easy to rupture and cause infections and pleurisy if not handled well. Usually when the renal cortical cyst is small, it will not cause symptoms or signs to the patients and it is often the case that the patients find that they have renal cortical cysts by accidence in the examination done for other illness or in the routine physical examinations. And someone can go through their entire life without knowing that they have the renal cortical cysts.

Though most renal cortical cysts are benign and usually not considered as a very serious illness condition, in some cases, the renal cortical cysts do cause many symptoms and complications to the patients. For example, with the gradual enlargement of the renal cortical cysts, they will cause pains in the back, abdomen. In the latter stage, the cysts will be easy to rupture and patients can sense lumps in the belly. If the renal cortical cyst replaces too much renal tissues and severely affects the kidney functions, it can lead to chronic renal failure though the incidence is very low (In America, there are about 2% of the chronic renal failure are caused by kidney cysts). So it is very necessary to have timely treatments once diagnosed with the disease especially when patients have signs or discomforts of the renal cortical cysts.

However at present the conventional treatments can’t take effect on small cysts because the puncture and decortication can only be operated on large cysts. Actually it should be the most appropriate time for the treatment when the renal cortical cysts are small in size before any substantial renal damages are caused. In this regard, the Chinese medicines should be a good choice because the Chinese medicines can act on both small and large cysts. At the same time of shrinking the renal cortical cysts, the Chinese medicines have the functions of repairing kidney damages and improve the kidney functions and the immunity of the body so that the curative effects are more durable compared with the hormones and surgery. What’s more, the therapy is safe and natural which does not cause any pains or side effects to the patients.
