Polycystic Kidney Disease
Overview of Polycystic Kidney Disease
Polycystic kidney disease is a genetic problem of kidneys inherited from parents. In this condition, fluid-filled cysts are formed inside the kidneys.
Signs and Symptoms of Polycystic Kidney Disease
Polycystic kidney disease is a genetic problem of kidneys inherited from parents. In this condition, fluid-filled cysts are formed inside the kidneys. These cysts can range from microscopic to large size tubules. This condition causes an increase in kidney size. It occurs due to mutational changes in the gene code for proteins involved in renal tubules formation. These cysts can develop either immediately after birth or during adolescence.
The severity of polycystic kidney disease can be different for every person. Often, in people between ages 55-65, polycystic kidney disease can reach the end-stage. However, others may develop mild diseases that never progress to the end-stage.
Occurrence of Polycystic Kidney Disease
Polycystic kidney disease is considered a common genetic disorder. Nearly 500,000 people in the United States are affected by this disease. The autosomal dominant is the most commonly occurring type of polycystic kidney disease. Autosomal dominant polycystic kidney disease affects 0.002% of people, while autosomal recessive types occur in 0.00005% of the population.

Types of Polycystic Kidney Disease
Some common symptoms of polycystic kidney disease are:
- High blood pressure
- Blood in your urine
- Back or side pain
- A feeling of fullness in your abdomen
- Increased size of your abdomen due to enlarged kidneys
- Kidney stones
- Urinary tract or kidney infections
- Kidney failure
- Pale skin colour
- Joint pain
- Nail abnormalities
In children symptoms of polycystic kidney disease may include:
- High blood pressure
- Urinary tract infections
- Frequent urination
Causes of Polycystic Kidney Disease
- Autosomal dominant polycystic kidney disease (ADPKD): This is the most common type of polycystic kidney disease. For its inheritance, only one parent needs to have the disease. Its symptoms often develop after 30 years of age. In the past, it was considered children’s disease but later it was found in adults too.
- Autosomal recessive polycystic kidney disease (ARPKD): This is the less common type of polycystic kidney disease. Usually, its symptoms appear immediately after birth but in some cases, they appear during adolescence
Polycystic kidney disease is a genetic disorder caused by mutated genes. In some cases, the mutation is spontaneous therefore its copy is not present in either parent.
ADPKD can be passed only from one parent. On the contrary, ARPKD can be transferred from both parents.
Health-Related Complications of Polycystic Kidney Disease
Polycystic kidney disease can lead to the following complications:
- High Blood Pressure (BP): Polycystic kidney disease often causes high blood pressure. If high BP is not treated properly it can cause further damage to the kidneys. Other complications such as heart problems and strokes can also occur.
- Loss of Kidney Function: With polycystic kidney disease, kidney function can be progressively impaired. About half of the people with PKD above age 60 experience this serious complication. PKD causes uremia, a condition in which toxic waste is accumulated in the body. In some server cases, end-stage renal failure may occur.
- Growth of Cysts in the Liver: development of liver cysts is the most common complication of PKD in adults. These cysts can develop in both males and females but mostly affect females. In females, multiple pregnancies and hormones are the major contributors to cyst formation.
- Heart Valve Abnormalities: Mitral valve prolapse is a heart problem associated with PKD. Every 1 person in 4 with PKD may develop this heart problem. In this condition, heart valves are no longer able to close properly.
- Colon Problems: A person with PKD has the chance to develop diverticulosis-a a colon problem in which its walls are weakened or sacs are formed on it.
- Development of an Aneurysm in the Brain: Aneurysm is a condition in which a blood vessel in the brain bulges. Upon its rupturing bleeding can occur in the brain. People with PKD have higher chances of aneurysms. If you have a family history of aneurysms, your risks of aneurysms are greatly increased.
- Pregnancy Complications: Often pregnancy is normal for women with polycystic kidney disease. But in some cases, women may develop preeclampsia, a life-threatening complication of pregnancy associated with liver or kidney damage.
Although polycystic kidney disease is a genetic disorder, its complications can be prevented by managing high blood pressure. It can be done by following tips:
- Take the blood pressure and maintain medicines as per the doctor’s recommendation.
- Consume a low-salt diet and add plenty of fruits, vegetables and whole grains to your diet.
- Maintain healthy body weight.
- Limit alcohol use.
- Abstain from smoking.
- Exercise regularly.
Treatment of Polycystic Kidney Disease | When to Consult a Doctor
Polycystic kidney disease can be diagnosed by performing various tests to detect the size and number of kidney cysts. These tests may include:
- Imaging Tests: Imaging tests such as X-ray, CT scan or MRI allows the doctor to see the detailed image of the kidney and locate the position of cysts.
- Ultrasonography: An imaging test that is performed to check the detailed image and location of the cyst. A wand-like device (transducer) is placed over the affected area of your body. Sound waves from the device travel through the tissues and when reflected back transforms into an image on the computer screen. Sometimes ultrasound is performed several times to check whether a cyst is growing or a new one is formed.
- Venography or Ascending Phlebography: In venography, an X-ray of the vein is taken to obtain a detailed image. A dye is injected through a catheter into the blood vessels.
