Background and study aims
Obstetric fistula is a hole in the birth canal caused by prolonged and obstructed labour. If left untreated in a patient, this leads to incontinence (constant and uncontrollable leakage of urine or faeces). When obstetric fistula (OF) repair takes place, the results are usually assessed by the surgical team and the patient perspective is often neglected. Urogenital distress inventory (UDI-6) and the impact of incontinence questionnaire (IIQ-7) are two internationally-validated questionnaires.
The aim of this study is to translate them in two Congolese local languages (Lingala and Kikongo) and to check whether that they can be used to assess the symptoms and the impact of urinary incontinence on the quality of life in patients with obstetric fistula.

Female adults with fistula due to obstetric complications and able to fill in questionnaires

Scientific title	Validation of the UDI- and IIQ-7 questionnaire in Lingala and Kikongo in an obstetric fistula population - an observational study
Study objectives	Urogenital distress inventory (UDI-6) and the impact of incontinence questionnaire (IIQ-7) are two internationally validated questionnaires on incontinence. It is hypothesised that these questionnaires can be translated and validated in two Congolese local languages (Lingala and Kikongo) and that they can be used to assess the symptoms and the impact on the quality of life of urinary incontinence in patients with obstetric vesicovaginal fistula.
Ethics approval(s)	Internal Review Board of the Hospital St. Luc, Kisantu, RD Congo
Health condition(s) or problem(s) studied	Vesicovaginal fistula due to obstetric complications in a rural hospital in DR Congo
Intervention	Questionnaires, according to following methodologies. - UDI-6 and IIQ-7 translated and undergoing content validity checks using focus groups. - Final versions tested in a normal population and in an obstetric fistula population for internal consistency and test-retest reliability. - Responsiveness tested in an obstetric fistula population and effect sizes calculated.
Intervention type	Other
Primary outcome measure(s)	Validation parameters: Crohnbach alpha, reliability, responsiveness
Key secondary outcome measure(s)	1. Fistula closure rate - number of healed fistula vs the number of persistent fistula after fistula surgery. This is assessed by clinical examination after 3 weeks. 2. Incontinence rate - number of patients with urinary incontinence ( stress and/or urgency incontinence) while the fistula is healed. This is assessed by clinical examination at 3 weeks and 3 months after surgery.
