To diagnose cystitis, your doctor may use:
- Cystoscopy, which puts a thin tube with a camera into your urethra to look for problems or get a tissue sample.
- Imaging. An ultrasound, CT scan, and MRI can show issues.
- Intravenous urogram (IVU). It’s an X-ray that takes images of the kidneys, ureters, and bladder.
- Voiding cystourethrography, which puts dye into your bladder to see if any urine flows backward.
- Retrograde urethrography, which uses contrast dye to find problems in the urethra.
