Outcome Measures

Primary Outcomes (1)

  • Change in Participant Reported Pain Score From Baseline to Intra-Procedure

    Using the participant-reported numerical pain scale, the change in participant reported pain was measured. This change was measured between two time points, baseline and intra-procedure. The participant-reported pain scale ranges from 0 (no pain) to 10 (worst pain) with higher scores indicating worse pain. When analyzing the data, the scale was multiplied by a factor of 10 to get a 100-point scale. Final results are reported using the 100-point scale ranging from 0 (no pain) to 100 (worst pain) with higher scores indicating worse pain.

    Baseline; intra-procedure

Secondary Outcomes (1)

  • Change in Participant Satisfaction From Post Procedure to 10 Minutes Following Completion of Cystoscopy

    Postprocedure, 10 minutes following completion of cystoscopy
