What this trial studies

This clinical trial aims to evaluate the effectiveness and acceptability of an insertable vaginal cup for managing urinary incontinence caused by obstetric fistula. Participants will be women awaiting fistula surgery or those whose previous surgery was unsuccessful. The study will compare two intervention models: a standard vaginal cup and a modified version connected to a urine collection bag. The trial will involve a cross-over design with 100 participants observed over four days to assess the performance and user satisfaction of each device.

Who should consider this trial

Good fit: Ideal candidates are women with confirmed vesicovaginal fistula who are at least 18 years old and willing to use the insertable devices.

Not a fit: Patients with rectovaginal fistulas or those who have minimal urinary leakage may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a non-surgical management option for women suffering from obstetric fistula-related urinary incontinence.

How similar studies have performed: While the use of insertable devices for menstrual management has been studied, this specific application for obstetric fistula management is novel and has not been extensively tested.
