A cyst is a small or round thin-walled sac with watery fluid insides and it can grow in any part of the kidneys, such as renal cortex, renal parenchyma, etc. And along with aging (especially people who are above 50 years old), people will have one or sevreal simple kidney cysts. And the size of these cysts may also increase with age. Well then, when should a renal cyst be treated?

To be frank, simple kidney cysts usually do not cause symptoms so that the small cysts can be easily ignored. In most cases. A doctor finds them during an ultrasound or computerized tomaography (CT) scan. However, some cysts do cause several symptoms:

Pain in your back, side or upper abdomen when cysts enlarge and press on other organs and tissues.

Bleed, blood in urine.

Infections such as urinary tract infection.

Fever, cold and chills.

Poor kidney function (Kidney Failure). It is rare in clinical except for Polycystic Kidney Disease.

Well then, when should a renal cyst be treated?

Generally, when the cysts are smaller than 3cm and patients have no injury or discomforts, usually no special treatments is offered and most physicians adopt a wait and see attitude. But it is also crucial to have regular follow-up checks including routine urine test, blood test, renal function and so on. However, when the cysts is more than 3cm and begin to suffer from the symptoms as the above mentioned, the treatment should be applied as early as possible. In western countries, surgery is commonly used for removing cysts which can remove the cysts and alleviate pains and discomforts in a short time. And it is more suitable for signal and surfaces cysts and the recurrent rate is high and they cysts will once again appear after the surgery.

Therefore, we can see that surgery is not an ideal treatment to shrink kidney cysts. In China, Shijiazhuang Hetaiheng Hospital, China, we do use herbal medicines for shrinking cysts and repair kidney damage. Some Chinese herbal medicines have the functions of dilating blood vessels and cleaning blood stasis so as to increase the blood supply in the kidneys.
