How about the answer?

Simple kidney cyst is filled with clear fluid, and it can appear in any part of kidneys, such as renal cortex and renal parapelvic. Cysts in different areas can cause various problems, if they become too bigger. For example, renal parapelvic cysts are more likely to cause urinary tract infections or pyelonephritis.

Generally speaking, if the person’s kidney cyst is small and hasn’t caused any symptom, the only thing he needs to do is to modify his diet and lifestyle. Besides, regular examination is also necessary. Limit the intake of salt and protein, quit alcohol and smoking, control the consumption of coffee and chocolate, etc. All of these tips can help slow down the growth of kidney cysts.

However, if the kidney cyst becomes too big or has caused some discomforts, patients should take some treatments to drain or shrink their cyst. So far, there are two treatment options.

One is surgery. Doctors use a long needle to puncture the kidney cyst via skin under the guidance of microscopic. Then, some substances containing alcohol are filled into empty sac, to harden it and reduce the recurrence of kidney cyst. However, in some cases, patients do have kidney cysts again.

The other is Traditional Chinese Medicine (TCM). Through increasing the permeability of cystic walls and improving the blood circulation, sac fluid can be discharged out of the body via urine. Compared with surgery, it can prevent the recurrence effectively, but it may need a little longer time to work. Therefore, you should be patient, once you decide to use TCM.
