What is a renal cortical cyst?

Could be normal: Cysts in the kidneys could be a normal finding if they are simple and one or 2 in number. They may be a sign if a disease called poly cystic kidney disease if they are numerous and bilateral depending on age and if there is family history. Cysts occur with aging and usually if someone is on dialysis they may have cysts.

Common: Renal cortical cysts fall into 2 categories: simple and complex. A simple cyst usually requires no further treatment and are fairly common. They may require drainage or removal if they grow too large. A complex cyst requires close follow-up and possible treatment, as some may represent a cystic form of kidney cancer. Talk to your doctor or see a urologist for further evaluation.

Nothing: Simple renal cortical cysts are common incidental findings. They do not turn into cancer. They are benign and generally require no treatment.

Here are some ...: If the diagnosis for renal simple cortical cyst has been well-established according to the imaging study - usually with renal ultrasound, the most reasonable course of care is leaving it alone with periodic renal ultrasound, one time in one year and another time in another two years. It remaining stable, there is no need for further test. For further information? Ask Dr. timely.
