[An urethromanometric study using micro-pressures gauges for female urinary incontinence. A definition of the index of continence. Applications (author's transl)]

Area of Science:

• Urology
• Gynecology
• Physiology

Context:

• Urinary incontinence affects a significant number of women, impacting quality of life.
• Accurate diagnosis and quantification of female incontinence are crucial for effective management.
• Existing diagnostic methods may not always be sufficient for complex cases.

Purpose:

• To develop and validate a quantitative measure for female continence using urethral pressure profilometry.
• To assess the utility of a novel index of continence (IC) derived from urethral pressure curves.
• To explore the diagnostic and therapeutic applications of the IC in managing female urinary incontinence.

Summary:

• Urethral pressure curves were analyzed at rest and during coughing in 34 continent and 100 incontinent women.
• A new index of continence (IC) was derived from the ratio of pressures during maximum effort and maximum rest.
• The IC demonstrated a clear distinction between continent and incontinent individuals, correlating with sphincter function.

Impact:

• The IC provides a quantitative assessment of the sphincter apparatus's adaptive capacity, offering a valuable tool for diagnosing female incontinence.
• This method can aid in confirming diagnoses, tailoring therapies for difficult-to-treat cases, and identifying women at risk of future incontinence.
• Potential to unmask incontinence masked by conditions like prolapse and identify pre-clinical cases.
