What is the rate of incidence of ADPKD?
Autosomal dominant polycystic kidney disease (ADPKD) is inherited as an autosomal dominant trait in families. While many people with ADPKD have a family member with the same condition, ADPKD can also occur in an individual without a family history of ADPKD. This happens as the result of a new genetic change in one of the genes that causes ADPKD.

This means having a well-balanced diet, staying physically active, learning how to manage pain and finding effective ways to communicate with your health care team.

What causes cysts in kidneys?
Kidney cysts occur when the tube of a nephron begins to get bigger and fill with fluid. Researchers don't know what causes this to occur, but they do know that simple cysts aren't inherited. It is believed that injury or microscopic blockages in the tubules may lead to the development of some simple kidney cysts.

How to diagnose ADPKD?
Usually, the diagnosis of ADPKD is initially performed by renal imaging using ultrasound, CT scan, or MRI. However, molecular diagnostics can be necessary in the following situations: 1- when a definite diagnosis is required in young individuals, such as a potential living related donor in an affected family with equivocal imaging data; 2- in patients with a negative family history of ADPKD, because of potential phenotypic overlap with several other kidney cystic diseases; 3- in families affected by early-onset polycystic kidney disease, since in this cases hypomorphic alleles and/or oligogenic inheritance can be involved; and 4- in patients requesting genetic counseling, especially in couples wishing a pre-implantation genetic diagnosis.
What is the treatment for ADPKD?
Treatment. Currently, the only clinical/pharmacological treatment available for ADPKD consists in reducing the speed in gain of total kidney volume (TKV) with aquaretics (i.e. tolvaptan) , which can alleviate pain while giving the patients a better quality of life for over a mean of 3 years.

Laparoscopic cyst decortication. Laparoscopic cyst decor tication (also referred to as marsupialization) consists in the removal of one or more kidney cysts through laparoscopic surgery, during which cysts are punctured, and the outer wall of the larger cysts is excised with care not to incise the renal parenchyma.
Is ADPKD a heterogeneous disease?
ADPKD is genetically heterogeneous with two genes identified: PKD1 (chromosome region 16p13.3; around 85% cases) and PKD2 (4q21; around 15% cases). Several genetic mechanisms probably contribute to the phenotypic expression of the disease.
Can an infant have a large echogenic kidney?
The findings of large echogenic kidneys without distinct macroscopic cysts in an infant/child at 50% risk for ADPKD are diagnostic. In the absence of a family history of ADPKD, the presence of bilateral renal enlargement and cysts, with or without the presence of hepatic cysts, and the absence of other manifestations suggestive of a different renal cystic disease provide presumptively, but not definite, evidence for the diagnosis. In some cases, intracranial aneurysms can be an associated sign of ADPKD, and screening can be recommended for patients with a family history of intracranial aneurysm.
