Hypothesis / aims of study
NICE guidelines 2018, currently out to consultation, suggest that urodynamic assessment is NOT required in women with stress predominant mixed urinary incontinence (MUI) prior to surgical intervention. This is based predominantly on expert opinion, as data on this topic is sparse. We have assessed the predictive power of the predominant symptom of MUI to determine the underlying urodynamic abnormalities to further clarify this issue.
Study design, materials and methods
Over a 4-month period from June to September 2018, 35 women with a mean age of 55years (range 26-86) with MUI attended for video-urodynamic studies (VUDS). They were asked a predefined set of questions aimed at assessing the predominant symptomatic component of their incontinence. Immediately following the questionnaire, VUDS were performed in accordance with ICS guidance.
Statistical analysis was by Chi Squared analysis and analysis of sensitivity, specificity, positive and negative predictive values.
Interpretation of results
Symptomatic SUI is predictive of USUI in women with MUI in 90% however concurrent DO is missed in 40%. Symptomatic UUI is predictive of DO in 64% and USUI is missed in 55%.
