Since symptoms are rare, a person will not normally know they have a kidney vesicle and it is often detected by accident, when a scan or trial for something else is performed. simple kidney cysts are more likely to develop as a person ages. approximately one quarter of people who develop these cysts are 40 years or older and around half are 50 years or older .
A complex kidney vesicle is a vesicle that has a more irregular form or compact walls than a simple cyst. broadly, the larger and more complex the vesicle is, the greater the gamble of it turning cancerous. complex cysts are consequently cautiously monitored and removed, if required .


The kidneys are comprised of bantam lineage vessels that transport blood to approximately one million percolate tubes referred to as nephrons. A cyst arises when one of these tubes expands, but the claim reason the pipe expands is not even known.


Although kidney cysts do not normally cause symptoms, some may cause a dull pain in the back or upper abdomen if they grow large enough .
occasionally, they become infect, in which sheath a person may develop a fever, deoxyadenosine monophosphate well as suffering from annoyance and tenderness .
They can besides cause hard annoyance in the back or side if they burst. A vesicle that blocks the normal flow of urine may cause the kidney to swell, which is referred to as hydronephrosis .


If a simple kidney cyst is causing symptoms or obstructing urine hang, it may need to be treated.

Under ultrasound guidance, the vesicle is punctured using a long needle and drained. This is called sclerotherapy. This procedure is normally carried out on an out-patient basis and does not require overnight stay in the hospital .
