My 17 yr old son had the right kidney removed 4 yrs ago. It had been damaged due to a
blockagePeripheral artery disease, they're not sure when. At the post surgical check up they found a cyst in the left one. In the 4 years it has shrunk from 1.5 cm to 1.3 cm. It is in an usual
spotBirthmarks - pigmented
Liver spots
Measles, koplik spots - close-up
Mongolian blue spots though. It is in the centre of the kidney not out closer to the wall. Could it move and cause a
blockagePeripheral artery disease? Is it
commonCommon cold or something to worry about? Of course I'm worrying.

Dear Debbie,
A cyst in the kidney is something that needs to be followed with periodic radiologic studies and
renalAcute kidney failure
Addison’s disease
Adrenal gland biopsy
Adrenalectomy
Cancer - renal pelvis or ureter
Catecholamines - blood
Chronic renal failure
Dialysis
End-stage kidney disease
Kidney diet - dialysis patients
Kidney stones function studies, most likely ultrasound and
creatinineCreatinine clearance. A cyst is almost always in the parenchyma and rarely would be a source of obstruction. They may increase or decrease in size however they don’t move.
Your question regarding should you worry about this cyst in your son’s solitary kidney. I would respond by saying, it is important for the cyst to be followed over time, primarily as to his kidney function, but it is unlikely to ultimately cause a problem. It is a small cyst but you still need to make sure it doesn’t to develop into a more significant lesion. If the cyst doesn’t grow or cause pain, hypertension, hematuria (anemia)or other symptoms, the cyst will not cause your son any difficulty. In the mean time there is nothing to worry about but rather be aware of the follow-up that should take place to keep your son healthy. As an aside, if your son is like any other 17 year old, he is not going to want to go to the doctors office every year or so. Make sure he knows what his situation is and what needs to be done in the future. I would ask your doctor to discuss this with him.
