Simple renal cysts may be caused by lymphatic developmental abnormalities or by infection leading to lymphatic obstruction and subsequent lymphatic edema. Acquired renal cysts may result from a reduction in functional nephrons due to dialysis in patients with renal failure. Additionally, there is a certain association with patient age; the likelihood of developing renal cysts increases after the age of 45.
