Treatment of mixed urinary incontinence

Abstract

Introduction: Mixed urinary incontinence (MUI) is a prevalent condition and imposes a significant impact on a woman's quality of life. Treatment is often challenging, as a single modality may be inadequate for alleviating both the urge and stress component.

Materials and methods: A MEDLINE search was conducted regarding English-language literature pertaining to the pathophysiology, diagnosis of, and treatment for MUI. Non-English language articles were considered if they could be translated into English using GOOGLE translator.

Results: The identification of an ideal single treatment has also been made more challenging by the poor characterization of the pathophysiology of MUI. Behavioral and lifestyle modification, as well as pelvic floor muscle therapy, should be considered first-line options for all women with MUI. Treatment of the urge component with anti-muscarinics is effective; however the stress component is likely to persist after therapy. Anti-incontinence surgery may have a positive impact on both the stress and urge components of MUI, with emerging evidence suggesting that transobturator MUS may be associated with lower rates of de novo and persistent urge component compared to other procedures. The presence of concomitant, preoperative detrusor overactivity has not been consistently associated with postoperative outcomes.

Conclusions: The optimum treatment of MUI may often require multiple treatment modalities. While surgery may have a positive impact on both the urge and stress component, its implementation should be approached with caution and patients should be carefully selected. Detailed informed consent in women with MUI cannot be overstated.
