A kidney cyst or renal cyst, is a fluid collection within the kidney. Most kidney cysts are âsimpleâ or âbenignâ meaning no treatment is required. Some cysts are more âcomplexâ and require either close radiographic imaging (with either a CT scan or MRI) or surgery since these cysts can be cancerous.
Definition of a Simple Renal Cyst. Simple renal cysts occur unilateral or bilateral, single or multiple. Renal cysts are usually circular, filled with clear fluid and have no connection to the pyelocaliceal system. The prevalence rate of kidney cysts increases with age: 20% with 40 years, 33% with 60 years of age.
