Intravenous Pyelogram
An intravenous pyelogram is an x-ray image of the bladder, kidneys, and ureters. Doctors will inject an opaque dye, which is visible on x-ray film, into a vein and then take a series of x-rays. The film will show an outline of the urinary tract and reveal even the small changes in the structure of the tract.
Ultrasound
If you have chronic
urinary tract infections, your doctor also may recommend an ultrasound exam. An ultrasound is a method of obtaining images from inside the human body through the use of high-frequency sound waves. The reflected sound wave echoes are recorded and displayed as a real-time visual image.
Cystoscopy
Another useful test in diagnosing a
UTI is a
cystoscopy. A cystoscope is an instrument made out of a hollow tube with several lenses and a light source. A cystoscope allows the doctor to see inside the bladder from the urethra.
