Vibratory perception and female stress urinary incontinence

Area of Science:

• Urology
• Neurology
• Gynecology

Background:

• Stress urinary incontinence (SUI) is a common condition affecting women's quality of life.
• Clinical evaluation of SUI often involves assessing pelvic floor muscle function.
• Vibratory perception threshold (VPT) is a measure of sensory nerve function.

Purpose of the Study:

• To evaluate the clinical utility of measuring vibratory perception threshold using a biothesiometer in women with SUI.
• To determine if VPT correlates with the presence or severity of SUI.

Main Methods:

• A comparative study involving three groups: women with SUI, age-matched controls without SUI, and younger controls.
• Vibratory perception threshold was measured using a biothesiometer on the middle finger, middle toe, and clitoris.
• Videourodynamics were performed in a subset of women with SUI.

Main Results:

• Women with SUI and age-matched controls were older and had higher parity than younger controls.
• No significant difference in VPT was found between women with SUI and age-matched controls.
• Women with SUI who experienced leakage during stair walking had higher finger and toe VPTs.

Conclusions:

• Vibratory perception, as measured by VPT, is not directly related to the presence of SUI in women.
• Reduced vibratory sensation in the fingers and toes may be associated with SUI, particularly during activities like stair climbing.
