Diagnosing a UTI
- Urine sample analysis: The doctor could request a urine sample to check for the presence of red blood cells, white blood cells, or bacteria. To avoid potentially contaminating the sample, the doctor may instruct the patient to wipe their genital area with antiseptic pads and to collect the urine midstream.
- Bacterial culture: Following a urine analysis, a urine culture is sometimes needed. The culture helps the doctor identify what bacteria caused the urinary tract infection as well as the most effective medication for treatment.
- Urinary tract imaging: Patients that suffer from frequent UTIs could have an abnormality in their urinary tract. To rule out any abnormality, the doctor may order magnetic resonance imaging (MRI), an ultrasound, or a computerized tomography (CT) scan. Contrast dye could also be used by the doctor to highlight structures in the urinary tract.
- Using a scope to inspect the bladder: For patients with recurrent UTIs, the doctor could perform a cystoscopy to see inside the bladder and urethra. The long, thin tube (cystoscope) has a lens and is inserted in the urethra and passed through to the bladder.
