Overview

Polycystic kidney disease is a genetic condition that causes many fluid-filled cysts to form in the kidneys. These cysts grow over time and replace healthy kidney tissue, making it harder for the kidneys to function properly. PKD is usually passed down from parents to children. It can slowly cause chronic kidney disease or kidney failure. The most common type of PKD, called autosomal dominant PKD, usually shows up in adults. A less common type shows up in babies or young children. The kidneys may become uncomfortable and cause problems as they get bigger. Early diagnosis and regular check-ups can help control symptoms and slow the progression of the disease.

Symptoms
Symptoms often appear in adults and may include high blood pressure, back or side pain, frequent urinary tract infections, and blood in the urine. People may feel tired and swollen, and may notice changes in their urination as their kidneys stop working properly. Abdominal fullness can occur when the kidneys enlarge. In advanced cases, signs of kidney failure may show up.

Causes
Inherited gene mutations that change how kidney cells grow and how fluids are regulated cause polycystic kidney disease. In autosomal dominant PKD, only one parent who has the disease needs to pass it on. The disorder causes the kidneys to form abnormal cysts. A family history is a big risk factor, but spontaneous mutations can also happen.

Diagnosis
Family history and imaging studies are often used to diagnose. Ultrasound is a common method for detecting kidney cysts. A CT scan or MRI can provide detailed images of the cyst and the kidney. Blood and urine tests assess kidney function and monitor disease progression.

Treatment
There is no cure for PKD, but treatment aims to control the symptoms and slow down the damage to the kidneys. It is very important to keep blood pressure under control. At times, medications may help slow cyst growth. It's important to manage pain, treat infections, and make lifestyle changes, such as reducing salt intake. Dialysis or a kidney transplant may be necessary for advanced cases.

The outlook depends on how severe the disease is and how quickly it worsens. With the right care, many people can keep their kidneys working for years. Early monitoring and management greatly postpone complications and enhance long-term quality of life.
