APPLIED RADIOLOGICAL ANATOMY

Detailed explanation-1: -Most people have two kidneys, which are organs shaped like kidney beans, each one about 10-15cms long, located either side of the spine, deep in the abdomen. However, it is possible to live a healthy and active life with only one functioning kidney.

Detailed explanation-2: -Some people are born with one kidney, known as renal agenesis. Others are born with two kidneys, but only one functions, referred to as kidney dysplasia. Dr. Mital says a benefit of possessing two functioning kidneys is having a sort of reserve in case of accident or injury.

Detailed explanation-3: -Although most people have two kidneys, you only need one functioning kidney to live an active, healthy life. If you have only one kidney, it’s important to protect it and keep it functioning well because you don’t have a second one to take over if it fails.

Detailed explanation-4: -Duplex kidneys occur in 1% of the population, the most common complication being infections caused by urine flowing back up to the ureter. But some patients have been delighted with their extra organs.

Detailed explanation-5: -Thus, we assume that the reason we have two kidneys is so that there is some extra reserve of kidney mass in case we sustain some renal insult (e.g. toxic injury, or traumatic injury). Having said that, about 1 in 1000 individuals are born with one kidney (unilateral renal agenesis).
