Your kidneys are two bean shaped organs in the back of your abdominal cavity on either side of your spine. Kidney cysts are extremely common and can be found in up to 80% of the population. Many patients are found to have kidney cysts after undergoing imaging for another condition.
Kidney or renal cysts are classified into simple and complex. The majority of patients have simple renal cysts. A smaller proportion of patients have complex renal cysts that may require further testing to differentiate the cyst from a kidney cancer.
Kidney cysts are typically diagnosed by ultrasound, computerized tomography (CT Scan) or magnetic resonance imaging (MRI). For the most part it is very easy to distinguish a simple renal cyst from a complex one on these tests. Occasionally, it is necessary to order a second radiologic test to definitely determine the cyst’s characteristics.
In general simple renal cysts are asymptomatic and require absolutely no further testing. They do not progress into cancers.
For those patients with complex renal cysts Urological Surgical Associates can provide accurate testing and treatment options. These cysts do need further evaluation to ensure they are not cancerous.
