There are two kidneys in the body on the right and left sides, which have a significant role in metabolism, as outlined below.
Any impaired kidney function leads to all these associated organs being affected, such as increased blood pressure, improper bone functioning and blood cell formation. So, whenever a kidney disease is suspected, early diagnosis and treatment is very essential. This results in minimal treatment and better prognosis.
Most people undergo an annual chemical test to check the blood and urine, which would indicate increase in protein levels or other abnormalities. When there is increase in the protein level, a kidney disease needs to be ruled out. One of the best ways to identify renal issues is to do a renal scan. Some of the common reasons for getting a renal scan done are listed below:
What is done?
A radioisotope material is injected into a vein and the flow of this material is then monitored. This scan evaluates the blood flow through and to the kidneys; how the urine flow takes place; and the size/structure of the kidneys. The scan will take about two hours to complete. A renogram is a graph that shows the flow of the tracer through the kidney.
A different density of uptake indicates different disease conditions. It is usually a painless procedure other than the slight discomfort caused by the needle prick. The results are usually available within two days for the doctor to interpret and take appropriate action.
