Associations between obstructive sleep apnea risk and urinary incontinence: Insights from a nationally representative survey

Obstructive sleep apnea (OSA) and urinary incontinence (UI) are two prevalent health conditions with significant impacts on individuals' quality of life. Although they appear distinct in nature, a growing body of evidence suggests a potential interrelationship between these conditions. Our objective was to explore the association between the risk of OSA and the occurrence of UI within a nationally representative sample of U.S. adults. Utilizing cross-sectional data from the National Health and Nutrition Examination Survey spanning the years 2015 to 2020, we conducted an analysis on a sample comprising 8,647 adults who provided comprehensive self-reported information on both UI and sleep apnea symptoms. The included cohorts were analyzed based on their sex. We employed the Multivariate Apnea Prediction (MAP) index to evaluate the risk of OSA. Subgroup analyses were conducted, categorizing them according to different types of UI. The association between OSA risk and UI was estimated through multivariable binary logistic regression models. After adjusting for relevant confounders, our results revealed a positive correlation between OSA risk and UI in both males (OR = 5.68, 95% CI = 1.74-18.47) and females (OR = 5.99, 95% CI = 2.68-13.41). The subgroup analysis illustrates that an elevated risk of OSA heightens the likelihood of experiencing stress urinary incontinence (SUI), urge urinary incontinence (UUI), and mixed urinary incontinence (MUI) in both male and female populations. Our study findings imply that an elevated risk of OSA exacerbates the likelihood of UI, SUI, UUI and MUI.

The Use of Uroflowmetry as a Diagnostic Test

PURPOSE OF REVIEW

Uroflowmetry is widely used for initial non-invasive evaluation of lower urinary tract disorders. Current clinical use is mostly restricted to a scrutiny of the maximum flow rate and uroflow pattern recorded by a conventional flowmeter in a health care facility. There are several advancements in our understanding and in available technologies that promise to transform clinical utilization of this simple test.

RECENT FINDINGS

Several aspects of the uroflow test in addition to maximum flow rate and uroflow pattern show potential diagnostic utility. This includes flow acceleration, uroflow indices, uroflow-electromyography including lag time, stop uroflow test, and uroflow-based nomograms. There are initial attempts to use artificial intelligence in analysis. There is also new data with regard to factors influencing variability of uroflow testing that might influence the diagnostic value in as yet uncertain ways including diurnal variability, postural variability, locational variability, and operator variability. There are new technologies for uroflow testing in a home environment allowing for easy repetition. However, there are several challenges owing to a paucity of clinical data and standardization. There are also critical lacunae in terminology that need to be addressed. There are exciting new advancements in the field of uroflowmetry. However, there is need to standardize and validate the newer uroflow tracing analyses and technologies.
