Kidney Cysts
Overview
Kidney cysts are small, fluid-filled sacs that can develop on or inside the kidneys. They're often round or oval, and have a clear boundary.
Sometimes, these cysts are linked to conditions that affect how well your kidneys work. However, most cysts are harmless and are called "simple" kidney cysts. These simple cysts are not cancerous and usually don't cause any problems.
Doctors don't fully understand what causes simple kidney cysts. They might appear on just one kidney, or multiple cysts can develop on one or both kidneys. Crucially, simple kidney cysts are different from cysts associated with a serious condition called polycystic kidney disease. They are also different from "complex" cysts. Complex cysts need more careful monitoring because they could potentially change and become cancerous.
Simple kidney cysts are often discovered during medical tests for other health issues. Treatment isn't typically necessary unless the cysts cause pain or other symptoms. In those cases, your doctor will determine the best course of action.
Symptoms
Kidney cysts are often harmless and don't cause any problems. Most of the time, you won't even know you have one. However, if a cyst gets bigger, it can sometimes cause some discomfort. Possible signs include a dull ache in your back or side, a fever, or pain in your upper stomach. If you experience any of these symptoms, it's important to see your doctor.
When to see a doctor
If you're experiencing symptoms that might be related to a kidney cyst, it's important to schedule a visit with your doctor. Kidney cysts are fluid-filled sacs that can develop inside your kidneys. While some cysts are harmless, others can be a sign of a more serious condition. A healthcare professional can properly diagnose the issue and recommend the best course of action. Don't delay; make an appointment today to get checked out.
Causes
Kidney cysts are sometimes found and aren't always fully understood. One idea is that they form when a part of the kidney's outer layer gets a little damaged or weak. This weak spot can create a small sac, like a tiny pouch. Fluid builds up inside this pouch. Over time, this pouch separates from the rest of the kidney and becomes a cyst.
Risk factors
Kidney cysts, which are simple fluid-filled sacs in the kidneys, are more likely to develop as people age. However, they can happen at any point in a person's life. These types of cysts are somewhat more prevalent in men than women.
Complications
Kidney cysts, while often harmless, can sometimes cause problems. These problems include:
-
Infection: Sometimes, a kidney cyst can become infected. This infection can cause a fever and pain in the area of your kidney. You might feel sick overall.
-
Rupture (bursting): A kidney cyst can rupture, or burst. This is very painful, often causing sharp pain in your back or side. Sometimes, blood in your urine is a sign of a burst cyst. If you experience this, it's crucial to seek medical attention right away.
-
Obstruction: A kidney cyst can sometimes block the normal flow of urine. This can cause the kidney to swell. A swollen kidney can be uncomfortable and may lead to other problems if not addressed. This blockage can also cause pain and discomfort.
Diagnosis
Finding out if you have a simple kidney cyst often involves these steps:
1. Imaging Tests: Doctors use pictures of your kidneys to check for cysts. These pictures are made using methods like MRI (magnetic resonance imaging), CT scans (computed tomography), or ultrasound. These tests can show if a growth in your kidney is a harmless cyst or something more serious, like a tumor. Ultrasound is often the first test used because it's less expensive and doesn't use radiation. MRI and CT scans might be used later to get a clearer picture, if needed.
2. Kidney Function Tests: A blood test can help doctors see how well your kidneys are working. If a kidney cyst is affecting the kidney's ability to filter waste from your blood, the blood test results will likely show this. This helps determine if the cyst is causing any problems and how serious they might be. The test measures substances that the kidneys usually remove from your blood, like creatinine and blood urea nitrogen (BUN). Higher-than-normal levels of these substances can indicate kidney problems.
Treatment
Kidney Cysts: When Treatment Is Needed
Kidney cysts are common, often harmless fluid-filled sacs within the kidneys. Many people have them without experiencing any problems. If a cyst doesn't cause symptoms and doesn't affect how well the kidneys work, treatment might not be necessary. Instead, your doctor might recommend regular imaging tests like ultrasounds to monitor the cyst for any changes. Sometimes, a cyst can go away on its own.
However, if a kidney cyst causes symptoms like pain, discomfort, or changes in urination, treatment may be needed. Here are some options:
Treating symptomatic cysts:
-
Aspiration and sclerotherapy: In this procedure, a doctor inserts a needle to drain the cyst fluid. Then, a special solution is injected into the cyst. This solution causes scarring, preventing the cyst from refilling with fluid. The solution might be alcohol or a similar chemical.
-
Needle aspiration with sclerosis: A similar approach uses a thin needle to drain the cyst fluid and inject a solution to prevent the cyst from reforming. This method is less common than aspiration and sclerotherapy.
-
Surgery: Surgery is usually reserved for large cysts that cause significant symptoms. It involves making small incisions in the skin and using tools and a tiny camera to access the cyst. The cyst fluid is drained, and the cyst wall is removed. This procedure is less common for simple cysts and is more often used for complex cysts that might have signs of becoming cancerous.
Important Considerations:
- Monitoring: If a cyst is small and doesn't cause problems, regular checkups and imaging tests might be enough.
- Complexity: Some cysts are more complex than others. If a cyst changes over time or shows signs of potential problems, it's important to discuss it with your doctor for the best course of action.
- Hospital Stay: Some cyst treatment procedures may require a brief stay in the hospital.
