KIDNEY DISEASES

Kidney disease means your kidneys are damaged and can't filter blood the way they should. You are at greater risk for kidney disease if you have diabetes or high blood pressure. If you experience kidney failure, treatments include kidney transplant or dialysis.

Kidney Anatomy

Normal kidney position

The kidneys lie retroperitoneally (behind the peritoneum) in the abdomen, either side of the vertebral column. They typically extend from T12 to L3, although the right kidney is often situated slightly lower due to the presence of the liver. Each kidney is approximately three vertebrae in length.

Crossed fused ectopic kidney

Crossed fused ectopic kidney is an unusual congenital malformation of the urinary tract. This condition is usually identified in the autopsy specimen rather than in general clinical scenario. In this condition, both kidneys are located on one side of the midline and are fused with each other.

PUJ obstruction in right kidney

Pelviureteric junction (PUJ) obstruction/stenosis, can be one of the causes of obstructive uropathy. It can be congenital or acquired with a congenital PUJ obstruction being one of the commonest causes of antenatal hydronephrosis.

Vascular anomalies of the kidney

Vascular malformations of the kidney are disease processes that involve renal veins and arteries and include congenital arteriovenous malformations (AVMs) and arteriovenous fistulas. AVMs are congenital communications between arteries and veins with a vascular nidus that bypass the capillary bed.

Renal hilar vessels

The renal hilum (Latin: hilum renale) or renal pedicle is the hilum of the kidney, that is, its recessed central fissure where its vessels, nerves and ureter pass. The medial border of the kidney is concave in the center and convex toward either extremity; it is directed forward and a little downward.

Renal artery - Right

Renal refers to anything related to the kidneys. Renal arteries carry blood from the heart to the kidneys. They branch directly from the aorta (the main artery coming off the heart) on either side and extend to each kidney. These arteries take a very large volume of blood to the kidneys to be filtered.

Renal artery - Left

Renal refers to anything related to the kidneys. Renal arteries carry blood from the heart to the kidneys. They branch directly from the aorta (the main artery coming off the heart) on either side and extend to each kidney. These arteries take a very large volume of blood to the kidneys to be filtered.

Renal arteriogram

A renal arteriogram is a special type of X-ray picture that helps doctors see the blood vessels in your kidneys.

About the Kidney

​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. They remove wastes, control the body's fluid balance, and keep the right levels of electrolytes. All of the blood in your body passes through them several times a day. Blood comes into the kidney, waste gets removed, and salt, water, and minerals are adjusted, if needed. The filtered blood goes back into the body. Waste gets turned into urine, which collects in the kidney's pelvis -- a funnel-shaped structure that drains down a tube called the ureter to the bladder.Each kidney has around a million tiny filters called nephrons. You could have only 10% of your kidneys working, and you may not notice any symptoms or problems. If blood stops flowing into a kidney, part or all of it could die. That can lead to kidney failure.
