Multiple cysts in both kidneys, it actually means that the number of cysts in one kidney is more than four, and multiple cysts in both kidneys should be distinguished from polycystic kidneys. Although there are more cysts in both kidneys, it does not destroy the parenchymal structure of the kidney and usually does not affect the kidney function. If the diameter of the cysts is greater than 5cm or more, or if the corresponding compression symptoms are produced, such as lumbar pain and discomfort, kidney cyst puncture and drainage or laparoscopic decompression of kidney cysts can be performed. On the contrary, for patients with polycystic kidney, because it is a congenital hereditary disease and will destroy the structure of the kidney, it may eventually cause kidney failure, so these patients should be actively treated.
