Optimal storage conditions for urine cytology specimens depend on timing: 1) For immediate processing (<2 hours), room temperature is acceptable. 2) For delayed processing (2-24 hours), refrigeration at 2-8°C is recommended to slow cellular degeneration. 3) For longer delays (>24 hours) or transport, preservation with an equal volume of 50-70% ethanol or commercial cytology fixative (e.g., Cytolyt) is necessary. Boric acid can be added as a preservative if microbiology testing is also needed. Unpreserved urine should never be frozen as ice crystals rupture cells. Proper labeling and leak-proof containers are essential for all storage conditions.
