What is involved?
The ultrasound of the kidneys will be performed with the patient lying flat on the table on his/her back. The patient’s shirt will be lifted up and the pants lowered by the hip region. Sometimes the patient may be asked to lie on his/her sides to better optimize the kidneys. A small amount of warm gel will be placed on both sides of the abdomen and at the bladder region. The technician will be using a transducer that will be moved around on the patient’s kidney and bladder area to be able to produce images for the doctor. The test will take approximately 20 minutes.
