A Urine Collection Device (UCD) is used during spaceflight to collect and contain urine. A UCD consists of a storage bag, adapter tubing, and disconnect hardware for both the male and female adapters. Each UCD bag can store approximately 1 quart of urine. The bags are either disposed of in the spacecraft waste management system (WMS) or returned to earth for further research. UCDs are also used outside the spacecraft during Extravehicular Activity (EVA) operations.
