MRU is a non-invasive imaging procedure for detecting urinary tract disorders
Magnetic resonance urography (MRU) is an imaging procedure for creating detailed pictures of urinary tract (kidneys, ureters and bladder) using magnetic waves.
In fact, MRU is done in MRI machine and it could be done with furosemide and contrast taken intravenously. This helps the machine to provide more accurate images, helping doctors to diagnose any kind of urinary tract problems such as detecting blood in urine (hematuria), kidney or bladder stones, and cancer in the urinary tract.
It is also noted that MRU is painless and it is usually used for children and occasionally for younger adult patients.
