What you can expect

By Mayo Clinic Staff

A urine cytology test requires a urine sample. Most often this is obtained by urinating into a sterile container. In some cases, a urine sample is collected using a thin, hollow tube (catheter) that's inserted into your urethra and moved up to your bladder.

Examining the urine sample in the laboratory

Your urine sample is sent to a laboratory for testing by a doctor who specializes in examining body tissues (pathologist). The pathologist analyzes any cells seen in the urine sample under a microscope. The pathologist notes the types of cells and looks for signs in the cells that might indicate cancer.
