5. Design and Procedures To account for screen failures, it is anticipated that a total of 40 female controls will be screened to achieve n=20 for completed UDS. Subjects will perform a baseline voiding test (uroflow), then will be randomized to undergoing urodynamic studies with or without urethral analgesia. Participants will be randomized to their arm of the study using a random number generator (MatLab). Study staff and the subjects will be blinded to the treatment regimen; thus, this study design is a randomized double-blind placebo-controlled trial. Inclusion and exclusion criteria are listed in a separate section.
