<unk>  is a test that looks for abnormal cells in<unk>  under a microscope. The test commonly checks for infection, inflammatory disease of the<unk> ry tract, cancer, or precancerous conditions. If a cancerous condition is detected, other tests and procedures are usually recommended to diagnose cancers, including bladder cancer, ureteral cancer and cancer of the urethra. It is especially recommended when blood in the<unk>  (hematuria) has been detected.<unk>  typically contains epithelial cells shed from the<unk> ry tract, and<unk>  evaluates this<unk> ry sediment for the presence of cancerous cells from the lining of the<unk> ry tract, and it is a convenient noninvasive technique for follow-up analysis of patients treated for<unk> ry tract cancers. For this process,<unk>  must be collected in a reliable fashion, and if<unk>  samples are inadequate, the<unk> ry tract can be assessed via instrumentation, such as a catheter. In<unk> , collected<unk>  is examined microscopically. One limitation, however, is the inability to definitively identify low-grade cancer cells and<unk>  is used mostly to identify high-grade tumors. If the test detects atypical or cancerous cells, further tests may be recommended, such as cystoscopy and a CT scan.
