Urine cytology

Urine cytology is a test to look for abnormal cells in your urine. Urine cytology is used along with other tests and procedures to diagnose urinary tract cancers.

Urine cytology is most often used to diagnose bladder cancer, though it may also detect cancers of the kidney, prostate, ureter and urethra.

Your doctor may recommend a urine cytology test if blood has been detected in your urine (hematuria).

Urine cytology may also be used in people who have already been diagnosed with bladder cancer and have undergone treatment. In these cases, a urine cytology test may help detect a bladder cancer recurrence.


Why it's done Risks How you prepare What you can expect Results

Urine cytology is used along with other tests and procedures to diagnose cancers of the urinary tract, including:

  • Bladder cancer
  • Cancer of the ureter
  • Cancer of the urethra

Urine cytology can best detect larger and more-aggressive urinary tract cancers. Urine cytology might not detect small urinary tract cancers that grow more slowly.
