During the procedure
A urine cytology test requires a urine sample, which you provide 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.
After the procedure
Your urine sample is sent to a lab for testing by a doctor who specializes in examining body tissues (pathologist). The pathologist analyzes cells from the urine sample under a microscope, notes the types of cells and looks for signs in the cells that might indicate cancer.
