Swelling or inflammation in one or both the kidneys is known as hydronephrosis. Kidneys are the bean shaped organs located in the abdomen. Their function is to filter out waste products from the blood and produce urine. Each kidney is made up of two parts: one parts performs the function of filtering the blood and removing excess salt and water present. The other part collects the urine. When a person has hydronephrosis, too much urine is collected in that part of the kidney which performs the function of collecting urine. The excess urine results in swelling of that part and makes it larger than the usual.
