Exploring the link between menstrual cycles and urinary incontinence in women with spinal cord injuries

Urine Incontinence Occurrence and Sexual Hormones in Women With Chronic Spinal Cord Injury/Disease - a Pilot Study

Observational Swiss Paraplegic Research, Nottwil · NCT06892080

This study looks at how changes in hormones during the menstrual cycle might affect bladder control in women with spinal cord injuries to see if it can help improve treatment options.

What this trial studies

This observational pilot study investigates how fluctuations in sex hormones during the menstrual cycle may affect bladder function in women with chronic spinal cord injury. Participants will document their menstrual cycles and instances of urinary incontinence over three cycles, using diaries, saliva samples, and urine tests to gather data. The goal is to identify potential hormonal influences on urinary incontinence, which has been less studied in premenopausal women compared to postmenopausal women. Understanding these factors could lead to improved treatment options for affected individuals.

Who should consider this trial

Good fit: Ideal candidates are women aged 18 and older with chronic neurogenic bladder dysfunction due to spinal cord injury and a regular menstrual cycle.

Not a fit: Patients who have hormonal imbalances, such as oligomenorrhea or amenorrhea, or those on hormonal treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide insights that lead to better management and treatment of urinary incontinence in women with spinal cord injuries.

How similar studies have performed: While studies have explored urinary incontinence in postmenopausal women, this approach focusing on premenopausal women and menstrual cycles is relatively novel.
