Thus, it is possible to derive a certain regularity between the occurrence of cysts and trauma to kidney or infectious kidney disease. In addition, there is a connection between the occurrence of cysts, and genetic predisposition. In medicine, there is a certain classification of all types of cyst of the kidney:
