The kidneys play an extremely important role in the life of the body, therefore, it is necessary to ensure that they are healthy and treat their diseases in time. However, many kidney diseases develop asymptomatically and do not manifest themselves in the early stages. As a result, treatment can take a lot of time and effort.
What are the sizes of the kidneys in a healthy adult?
Even a person who considers himself to be absolutely healthy should have his kidneys examined from time to time - for example, an ultrasound scan. During this examination, it may turn out that the size of the kidney is enlarged. What are the reasons for this phenomenon?
Normally, in a person of mature age, the length of the kidneys is from 10 to 12 centimeters, the width is from 5 to 6 centimeters and the thickness is from 4 to 5 centimeters. Of course, any human body is individual, so slight deviations up or down are possible. This is a natural phenomenon. However, if the deviations exceed the indicated values by more than 20%, this in the overwhelming majority of cases indicates a disease.
In the event that ultrasound shows a significant increase in the overall size of the kidney or any of its internal structures, it is necessary to undergo additional examinations and tests. After the diagnosis is made, the doctor will prescribe treatment.
What diseases lead to an enlarged kidney
A common cause of kidney enlargement is pyelonephritis. This disease is manifested by the following symptoms: frequent urination, pain in the lumbar region (their nature and strength can vary widely), a feeling of weakness, weakness. During periods of exacerbation of pyelonephritis, the temperature rises, chills, fever occurs, and vomiting may begin.
Another common cause of kidney enlargement is hydronephrosis. In this disease, more urine is produced in the affected kidney than can be diverted through the ureter. Therefore, urine gradually accumulates in the calyx-pelvic system, which leads first to its increase, and then to an increase in the entire organ.
The most dangerous reason for an enlarged kidney is a malignant tumor. Her treatment should be started as early as possible! But, as already mentioned, in the early stages this disease (like many others) practically does not manifest itself in anything, therefore, unfortunately, it is found in most cases already in the later stages, when there is little chance of a successful cure.
Finally, an enlarged kidney can be caused by the absence of a second kidney in the body. This happens very rarely, and a person may not even suspect that he has only one kidney before the examination. And since a single organ has to work for two, its size naturally increases.
