Kidney cysts are round pouches of fluid that form on or in the kidneys. Kidney cysts can be associated with serious disorders that may impair kidney function. But more commonly, kidney cysts are a type called simple kidney cysts — noncancerous cysts that rarely cause complications.

PKD cysts can profoundly enlarge the kidneys while replacing much of the normal structure, resulting in reduced kidney function and leading to kidney failure. When PKD causes kidneys to fail-which usually happens after many years-the patient requires dialysis or kidney transplantation.

Blood in the urine This is called microscopic hematuria. Hematuria is more common in an individual with large kidneys and high blood pressure. It is thought that the rupture of cysts or of the small blood vessels around cysts is the cause. Other causes could include kidney or bladder infection and kidney stones.

Polycystic kidney disease (PKD) is an inherited disorder in which clusters of cysts develop primarily within your kidneys, causing your kidneys to enlarge and lose function over time. Cysts are noncancerous round sacs containing fluid. The cysts vary in size, and they can grow very large.

Simple kidney cysts are fluid-filled sacs that form in your kidneys. Though abnormal, these cysts usually don't affect how your kidneys work. Most simple kidney cysts don't cause any symptoms. They also usually don't need any treatment.

An epididymal cyst is a harmless little fluid-filled growth on a man's testicle (testis). They are quite common and don't usually require treatment. Many men feel them and are concerned they have testicular cancer, but a doctor can usually tell the difference.

Hemorrhagic cysts of the kidney are different from the ordinary, more common, thin-walled, serous cysts. Hemorrhagic cysts are smooth and continuous with the contour of the kidney surface and do not abruptly project from the renal parenchyma like serous cysts.

Your kidneys are two organs that sit in your abdomen on either side of your backbone. They're about the size of a fist and shaped like a bean. Your kidneys are responsible for cleaning your blood. They process your blood to sort out excess fluids, unwanted chemicals and waste, and turn these into urine.

Pancreatic cysts are saclike pockets of fluid on or in your pancreas. The pancreas is a large organ behind the stomach that produces hormones and enzymes that help digest food. Pancreatic cysts are typically found during imaging testing for another problem.

Hematuria is more common in an individual with large kidneys and high blood pressure. It is thought that the rupture of cysts or of the small blood vessels around cysts is the cause. Other causes could include kidney or bladder infection and kidney stones.

Abstract. Some renal masses have higher attenuation than the surrounding renal parenchyma at computed tomography (CT). Their hyperattenuation is usually the result of proteinaceous fluid or densely packed cells. Most hyperattenuating renal masses are benign hemorrhagic or protein-aceous cysts.

The kidneys are a pair of bean-shaped organs on either side of your spine, below your ribs and behind your belly. Each kidney is about 4 or 5 inches long, roughly the size of a large fist. The kidneys' job is to filter your blood.

Treatment may not be necessary If your kidney cyst changes and causes signs and symptoms, you may choose to have treatment at that time. Sometimes a simple kidney cyst goes away on its own.

Medullary Sponge Kidney. Medullary sponge kidney (MSK) is a congenital disorder, meaning it is present at birth. MSK occurs when small cysts (sacs) form either on tiny tubes within the kidney (known as tubules) or the collecting ducts (a channel where urine is collected for removal).

A kidney infection usually happens when bacteria, often a type called E. coli, get into the tube that carries urine out of your body (urethra). The bacteria travel up to your bladder, causing cystitis, and then up into your kidneys.
