In 2007 a group of 11 women suffering from vesico-vaginal (VVF) fistulas approached MSF nurse Esther Moring and her medical team in eastern Chad, asking for treatment. In order to help those women and countless others with fistulas in eastern Chad, Moring and an MSF team initiated a pilot fistula surgery program. Here, Moring describes what fistulas are and why starting this project was so important.
