Final answer:
Polycystic kidney disease is a genetic disorder that causes multiple cysts to develop in the kidneys. This disorder can lead to renal failure, ultimately requiring kidney transplantation or dialysis.
Step-by-step explanation:
Polycystic kidney disease (PKD) is a genetic disorder in which multiple abnormal cysts develop and grow in the kidneys. This progressive disorder can ultimately result in renal failure, which may require kidney transplantation or dialysis. Kidney failure occurs when the kidneys are no longer able to adequately filter metabolic wastes from the blood. Dialysis is a treatment option in which the patient's blood is artificially filtered through a machine to remove waste products.
