Basic Knowledge on Simple Renal Cyst

Simple Renal cyst is the most common one in renal cysts diseases. When it develops for a rather long time, it will become Chronic Kidney Disease. It usually generates in only one kidney and the cyst appears alone. In some cases, there will be more than one cysts in one kidney. Cysts in both kidneys are very rarely seen. At present, the exact reason for the cyst is not clear, but the cyst will not affect kidney function in a very serious way, especially when the cysts are not big enough. As a result, the treatment tends to be done without any surgery. However, when the cysts become too big, in western medicine, there is just an operation to cut off the cyst, but later then, the cyst will constantly grow. The disease course is long, just the same with other chronic kidney disease.

Simple renal cysts tend to be grow in the surface of kidney, but sometimes it is in the deep kidney, and at that time, the wall of cyst is close connected with renal pelvis and renal calices, and they can hardly be separated.
