En icke ärftlig njursjukdom som kännetecknas av en onormal vidgning av samlingsrören i njurmärgen och njurpapillerna. Samlingsrören innehåller cystor eller utbuktningar fyllda med en geléartad substans eller små njurstenar, vilket kan leda till infektioner eller obstruktion. Svampnjure måste särskiljas från medfödd eller ärftlig polycystnjure.
