Kidney cysts are a common condition and many people may have them without even knowing. In most cases, these cysts are harmless and do not affect kidney function. However, in some cases, they can cause discomfort or lead to complications. Understanding kidney cysts — what causes them, their types, and treatment options — can help you manage the condition better and seek timely care.
What Are Kidney Cysts?
Kidney cysts are fluid-filled sacs that develop on or inside the kidneys. They usually have thin walls and can vary in size. Most kidney cysts are non-cancerous and do not cause serious problems. Many people discover kidney cysts during routine health check-ups or scans done for other reasons. In simple cases, they do not interfere with the normal working of the kidneys.
Types of Kidney Cysts
There are different types of kidney cysts, and understanding them is important for proper management and treatment.

The most common type. Harmless, fluid-filled, and usually do not cause symptoms.
Complex Kidney Cysts
May have thick walls or solid parts. Need closer monitoring as there may be a risk of complications.
Polycystic Kidney Disease (PKD)
A genetic condition where multiple cysts form in both kidneys and can affect kidney function over time.
Acquired Kidney Cysts
Develop later in life, often in people with long-term kidney problems or those on dialysis.
