Kidney cysts are round pockets of fluid filled with fluid that form on or inside the kidneys. Kidney cysts can be associated with serious disorders that may impair kidney function, but most commonly, renal cysts are of a type called simple renal cysts, noncancerous cysts that rarely cause complications..
The following report provides everything you need to know about renal cysts, according to the website hopkinsmedicine
Kidney cyst symptoms
Simple renal cysts do not usually cause signs or symptoms, but if a simple renal cyst grows to a large size, it may be one of its symptoms:
Pain in your back or side.
Pain in the upper abdomen.
Causes of renal cysts
The causes of simple kidney cysts are not clear. One theory suggests that a kidney cyst develops when the surface layer of the kidney weakens and forms a pocket (diverticulum) which then fills with fluid, separates and develops into a cyst..
The risk of developing simple kidney cysts increases as you get older, but these cysts can occur at any age and simple kidney cysts are more common in men..
Complications of kidney cysts?
Kidney cysts can sometimes lead to complications, including:
The kidney cyst may become infected, causing fever and pain.
A ruptured kidney cyst causes severe pain in your back or side.
A kidney cyst that blocks the normal flow of urine may cause the kidneys to swell (hydrocephalus).
Simple kidney cysts can often be detected during imaging tests that are done for another condition. Simple kidney cysts, which do not produce signs or symptoms, usually do not require treatment..
