Introduction and hypothesis Patient history is often insufficient to identify type of urinary incontinence (UI). Multichannel urodynamic testing (UDS) is often used to clarify the diagnosis. Dynamic cystoscopy (DC) is a novel approach for testing bladder function. The primary objective of this study was to investigate the diagnostic agreement of UDS and DC in evaluating women with mixed urinary incontinence (MUI). Methods Women presenting with MUI were approached for enrollment if UDS and DC were planned for further investigation. Investigators were blinded to history and comparative test results. McNemar’s test and kappa coeffi- cient were calculated to assess agreement between UDS and DC. Receiver operating characteristic (ROC) analysis was used to explore the best possible filling sensation cutoffs for DC that would best predict the filling sensation cutoffs from UDS. Results Sixty participants were included, of whom, four were excluded for protocol violation. For the primary outcome measure of agreement, UDS and DC were concordant in 44/56 of stress urinary incontinence (SUI) cases (79%) with a κ= 0.54 and in 43/ 56 of urinary urge incontinence (UUI) cases (77%) with a κ= 0.54, indicating moderate, nearly substantial agreement. ROC 3 3 analysis identified the best prediction of DC first
