Polycystic kidney disease
Cysts - kidneys; Kidney - polycystic; Autosomal dominant polycystic kidney disease; ADPKD
Polycystic kidney disease (PKD) is a kidney disorder passed down through families. In this disease, many cysts form in the kidneys, causing them to become enlarged.
People with PKD have many clusters of cysts in the kidneys. What exactly triggers the cysts to form is unknown.
PKD is associated with the following conditions:
As many as half of people with PKD have cysts in the liver.
Exams and Tests
An examination may show:
- Abdominal tenderness over the liver
- Enlarged liver
- Heart murmurs or other signs of aortic insufficiency or mitral insufficiency
- High blood pressure
- Growths in the kidneys or abdomen
Tests that may be done include:
People with a personal or family history of PKD who have headaches should be tested to determine if cerebral aneurysms are the cause.
PKD and cysts on the liver or other organs may be found using the following tests:
If several members of your family have PKD, genetic tests can be done to determine whether you carry the PKD gene.
The goal of treatment is to control symptoms and prevent complications. Treatment may include:
- Blood pressure medicines
- Diuretics (water pills)
- Low-salt diet
Any urinary tract infection should be treated quickly with antibiotics.
Cysts that are painful, infected, bleeding, or causing a blockage may need to be drained. There are usually too many cysts to make it practical to remove each cyst.
More information and support for people with polycystic kidney disease and their families can be found at a kidney disease support group.
Treatment may relieve symptoms for many years.
People with PKD who don't have other diseases may be good candidates for a kidney transplant.
When to Contact a Medical Professional
Contact your health care provider if:
- You have symptoms of PKD
- You have a family history of PKD or related disorders and you are planning to have children (you may want to have genetic counseling)
Currently, no treatment can prevent the cysts from forming or enlarging.
