2013-03-28 16:50

PKD is a hereditary and chronically progressive kidney disease. In the early stage, both the number and size of the cysts in the kidneys are small and patients can have no obvious symptoms or discomforts and the cysts are often detected by accident in imaging tests done for other illness conditions.

But both the number and size of the cysts will increase along with time and they will in the end occupy the space of normal renal tissues and the kidneys will be greatly enlarged. Renal functions will be gradually lost and the illness will in the end develop into renal failure.

The following are 5 stages of PKD and symptoms of each stage.

Stage 1. It is the emergence period of PKD. Since it is congenital and most patients inherit the disease from their parents, renal cysts exist in the kidneys since birth. Only that the cysts are very small and cause no obvious discomforts. Usually the disease is not easy to be detected until the patient is 20 years old. However for those that have family members being diagnosed with the disease, it is suggested that early and regular checks should be done to rule out the possibility.

Stage 2. It is the growth period which means that the cysts will experience rapid growth during this stage and patients are mostly 30-40 years old. Patients at this stage will begin to have a series of symptoms and complications such as high blood pressure, urinary tract infections, back pain, etc.

Stage 3. It is the enlargement period of PKD. The cysts will continue to grow and the kidneys are greatly enlarged. Renal structures will be altered and renal functions will be affected. The larger the kidney is, the fewer kidney functions it has.

Stage 4. It is the rupture period. If the cysts continue to become larger and larger, they are at high risk of rupture because of oppression from the enlarged cysts. In case of cyst rupture, patients often have sharp pain, fever, chill, it is very important to have timely and proper treatment to control infections and prevent sepsis and acute renal deterioration.

Stage 5. It is the end stage of PKD and more than 85%-90% kidney functions have been lost. Some patients will have their kidneys removed and they have to rely on renal replacement therapies to sustain their life.
