Kidney Cysts

Nephrology

Kidney cysts, or renal cysts, are fluid-filled sacs that develop on the kidneys. While many kidney cysts are benign and do not cause symptoms or complications, some can lead to serious health issues. Whether you are a patient or a caregiver, we can provide you with the knowledge and resources to better understand and navigate the world of kidney cysts.

Types of Kidney Cysts

There are two main types of kidney cysts: simple kidney cysts and complex kidney cysts.

Simple kidney cysts are the most common type and typically do not cause symptoms or require treatment. They are usually round or oval in shape and contain a clear fluid.

Complex kidney cysts have irregular shapes and may contain solid components or septations. Complex kidney cysts are more likely to be cancerous and may require further evaluation and treatment.

What Causes Kidney Cysts?

The exact cause of kidney cysts is unknown, but they are thought to result from a combination of genetic and environmental factors. In some cases, kidney cysts can be inherited from a parent. Other risk factors for kidney cysts include age, as they are more common in individuals over 50, and a history of certain medical conditions, such as polycystic kidney disease. Smoking and high blood pressure may also increase the risk of developing kidney cysts.

Symptoms and Diagnosis of Kidney Cysts

In most cases, kidney cysts do not cause symptoms and are discovered during imaging tests for other conditions. However, it is essential to seek medical attention if any of the following symptoms occur:

Severe or persistent pain in the back or side
Fever
Blood in the urine
Frequent urinary tract infections
Difficulty urinating
Any other concerning symptoms.

To diagnose kidney cysts, our SMC nephrology specialists may perform a physical examination, order imaging tests such as ultrasound or CT scan, and recommend blood and urine tests to rule out underlying conditions or complications.

Treatment Options for Kidney Cysts

Treatment for kidney cysts depends on various factors, including the size and number of cysts, symptoms, and the risk of complications. Simple kidney cysts usually do not require treatment and can be monitored through regular check-ups and imaging tests. If a cyst causes symptoms or complications, treatment options may include draining the cyst using a needle, a procedure known as cyst aspiration, or surgically removing the cyst. In rare cases where a cyst is cancerous or causing significant damage to the kidney, a partial or total nephrectomy, which is the surgical removal of the kidney, may be necessary.

Frequently Asked Questions about Kidney Cysts

Q: Can kidney cysts be cured?

While there is no cure for kidney cysts, many cases do not require treatment and can be safely monitored.

Simple kidney cysts are less likely to become cancerous, while complex kidney cysts have a higher risk. Regular monitoring and evaluation by our specialists can help detect any potential cancerous changes.

Q: Can renal cysts cause kidney failure?

Kidney cysts typically do not cause kidney failure. However, in rare cases, large or multiple cysts can lead to complications that may affect kidney function.

Q: Can lifestyle changes help manage kidney cysts?

While lifestyle changes cannot cure kidney cysts, they may help minimize symptoms and reduce the risk of complications. Maintaining a healthy diet, staying hydrated, exercising regularly, managing stress, and quitting smoking can all contribute to kidney health.
