It can affect patients at any age. It can be managed by reducing your risk factors. Please discuss with your doctor for further information.


What are the symptoms of kidney cyst?

Kidney cysts typically produce no symptoms or signs. The symptoms of kidney cyst is not completely clear. Unless the cyst creates an obstruction in the kidney, the cyst does not compromise renal function. However, in younger patients, a kidney cyst can reduce kidney function to lower than normal.

Symptoms commonly observed in patients with kidney cyst are the those associated with rupture (hemorrhage), hematuria, pain, abdominal mass, or infection and hypertension.

  • Rupture of a single cyst can cause hematuria and or persistent pain.
  • Infection of a kidney cyst can occur resulting in infectious symptoms.
  • Compression of surrounding the cyst may lead to hypertension.

When should I see my doctor?

Kidney cysts are often diagnosed in X-ray during general health check. If you have any signs or symptoms listed above or have any questions, please consult with your doctor. Everyone’s body acts differently. It is always best to discuss with your doctor what is best for your situation.


What causes kidney cyst?

Kidney cysts result from genetic or non-genetic changes in the tissue structure of kidney. One theory suggests that kidney cysts develop when the surface layer of the kidney weakens and forms a pouch (diverticulum). The pouch then fills with fluid, detaches and develops into a cyst.

Risk factors

What increases my risk for kidney cyst?

Although kidney cyst affects patients at any age, it is more common in adults. A study shows that people older than 40 years old have a 20% risk, while people older than 60 years old are at a 50% risk.

There is an absent evidence to the association between Kidney cyst and genders in most reports but in the least two studies, men were affected more frequently than women.

How is kidney cyst diagnosed?

Tests and procedures used to diagnose simple kidney cysts include:

  • Imaging tests. Some kidney cysts can be found on ultrasonography, computer tomography (CT) and magnetic resonance imaging (MRI). Imaging tests can help your doctor determine whether a kidney mass is a cyst or a tumor.
  • Kidney function tests. Testing a sample of your blood may reveal whether a kidney cyst is impairing your kidney function.

How is kidney cyst treated?

The vast majority of simple cysts require no treatment. If your simple kidney cyst is causing signs and symptoms, your doctor may recommend treatment. Options include:

  • Puncturing and draining the cyst, then filling it with alcohol. Rarely, to shrink the cyst, your doctor inserts a long, thin needle through your skin and through the wall of the kidney cyst. Then the fluid is drained from the cyst. Your doctor may fill the cyst with an alcohol solution to prevent it from reforming
  • Surgery to remove the cyst. A large or symptomatic cyst may require surgery to drain and remove it. To access the cyst, the surgeon makes several small incisions in your skin and inserts special tools and a small video camera. While watching a video monitor in the operating room, the surgeon guides the tools to the kidney and uses them to drain the fluid from the cyst. Then the walls of the cyst are cut or burned away.

Treatment of kidney cyst can lead to the following complications:

  • Pain
  • Infection
  • Hypertension
