Kidney anatomy

Kidney - blood and urine flow

Renal veins

The x-ray table is hard and cold -- you may ask for a blanket or pillow. There is a sting when the anesthetic is given. You may feel some pressure and discomfort as the catheter is positioned. As the dye is injected, you may experience a burning sensation.

There may be tenderness and bruising at the site of the injection after the test.

The test will detect thrombosis (presence of a blood clot or clots that partially or completely blocks the vessel), tumors, and venous abnormalities. The test may also be used to measure hormone levels produced by the kidney.

This test is now performed only on rare occasions and has largely been replaced by CT scan and MRI.
