Simple cortical cyst
can occur normally as age advances. Only when it is multiple or the cyst is large enough to compress the renal tissues and impair its function, or when it gets infected or a hemorrhage occurs inside it, it needs intervention. Else, it can be followed up with USG by the same radiologist
every 6 to 12 mths.
Provided, your urea, creatinine
levels are normal and no evidence of proteinuria
, u dont need to take any medications. Just a periodical follow up is enough
