Approximately 150 women with nighttime urinary incontinence will take part in this prospective, open-label, randomized trial. Participants will use one of two different study devices during the study to manage urine output at night: PureWick™ System or the Hollister® Female Urinary Pouch External Collection Device. Participant device assignment will be random. Participants will use the assigned urine management device overnight while sleeping and will be followed for approximately 4 weeks.
