Diagnosed and undiagnosed cough-related stress urinary incontinence in women with refractory or unexplained chronic cough: Its impact on general health status and quality of life.

Background: Stress urinary incontinence (SUI) is common in women with chronic cough but may be overlooked. Objective: To determine the frequency of underdiagnosis of cough-related SUI and its impact on women's general health status and quality of life (QoL). Methods: Data were analyzed for 147 women with refractory/unexplained chronic cough. Relevant details were collected from clinical charts and a patient-completed survey. General health status was assessed using the EuroQoL visual analogue scale (EQ-VAS) and QoL with the cough-specific Leicester Cough Questionnaire (LCQ). Results: Women were classified into diagnosed (n = 32; 21.8%) or undiagnosed (n = 33; 22.4%) cough-related SUI, and no SUI (n = 82; 55.6%) groups. Women with versus without cough-related SUI perceived poorer health status and greater impact of cough on everyday lives. Mean LCQ scores were significantly lower in cough-related SUI groups versus no SUI group. In multivariate analysis, the presence of cough-related SUI was significantly associated with lower EQ-VAS and LCQ scores. Conclusion: In our cohort, 44% of women had cough-related SUI, and half were undiagnosed. Irrespective of diagnosis, impairment to everyday lives and QoL was similar. Diagnosing cough-related SUI may identify additional patients who can benefit from therapies to suppress cough and improve QoL.
