A kidney ultrasound is one noninvasive test to assess the size, shape, structure, and location of kidneys. Also, it can be used to examine related structures like ureters and blood flow to kidneys. Through ultrasound, you can know whether your kidneys are normal in these aspects.
If there are some signs that may reveal the onset of kidney disease, doctors may suggest a kidney ultrasound. From this test, you can get the following information:
- The size of your kidneys in length, width and thick
- Whether you have kidney cysts, tumors, fluid collection and obstruction within kidneys
- Infections within kidneys or around kidneys
- Kidney stones
- Evaluate transplanted kidneys
In some cases, kidney ultrasound can guide doctors to make some medical treatments. For example, to remove a large kidney cyst, doctors use a long needle to puncture cyst with guidance of ultrasound.
If you have severe obesity, intestinal gas or some others specific conditions, you can have some risks during kidney ultrasound. Therefore, you need to consult the doctor in detail and tell them your problems before doing this test.
