Description[edit | edit source]
- Obstetric fistula is an abnormal opening between a woman’s genital tract and her urinary tract or rectum causing urinary and faecal incontinence, ongoing genital infections, anaemia and neurological symptoms of the lower limb[1].
- It is most commonly caused by prolonged obstructed labour (although it sometime results from sexual abuse or as an unintended result of obstetric surgery). The child is often stillborn and there is a risk to future fertility if cervical damage has occurred[2].
- Unsurprisingly, this highly stigmatizing condition has a significant impact on mental health as well as social and conjugal relations[3].
- It is estimated that each year between 50 000 to 100 000 women worldwide are affected by obstetric fistula and that more than 2 million young women live with untreated obstetric fistula in Asia and sub-Saharan Africa[4]
Aetiology[edit | edit source]
Most common cause: Prolonged, obstructed labour (labour for 2 or 3 days)[5]
Could be avoided by:
delaying the age of first pregnancy,
cessation of harmful traditional practices
timely access to maternal and obstetric care (three delays - decision, journey, receiving appropriate skilled care)
Other (less common) causes:exual abuse and rape, the complications of unsafe abortions and surgical trauma (most commonly, injury to the bladder at caesarean section). Crohn’s disease, gynaecological cancer and infection. Iatrogenic causes: unintended consequence of colorectal anastomosis, anorectal operations, or radiation therapy (uncommon in low-resource settings)
Social causes that contribute to the issue: poverty, education, role of women in decision making, early marriage, harmful traditional practices, family planning - spacing of childbearing
Clinically Relevant Anatomy
[edit | edit source]
Obstetric fistula involves an abnormal opening between the vagina and the bladder (a vesicle-vaginal fistula or VVF) or the vagina and the rectum (a recto-vaginal fistula RVF). A prolonged obstructed labour can result in injuries affecting the renal system, genital tract and the neurological system[6].
Renal damage:
bladder - tissue loss from necrosis causes reduced volume and reduced bladder compliance
urethra - fibrosis of the urethra causing urine incontinence
ureters - substantial damage to the bladder neck may affect the ureteral orifices
kidneys - due to possible ascending infection
Genital tract injuries include:
vagina - fibrosis and vaginal stenosis may lead to infertility
cervix and possibly the uterus - cervical injury may lead to pelvic inflammatory disease and cervical incompetence
Neurological injuries:
Lumbo-sacral plexus - this suffers compression during the obstruction, resulting in lower limb neurological deficiencies, such as altered sensation, muscle weakness and contractures
Peroneal nerve compression - caused by prolonged squatting during labour and result in foot drop
Nerves in the bladder - if injuries can cause neurogenic bladder.
Mechanism of Injury / Pathological Process[edit | edit source]
Necrosis of surrounding tissue due to pressure of the baby’s head against the pelvis. The reduced flow of blood to the soft tissues surrounding the bladder, vagina and rectum results in necrosis of the tissue. If the mother survives, this kind of labour often ends when the fetus dies and gradually decomposes enough to slide out of the vagina. The injured pelvic tissue also rots away, leaving a hole, or a fistula, between adjacent organs
VVF, RVF or combined
Clinical Presentation[edit | edit source]
Urinary or Faecal incontinence
Diagnostic Procedures[edit | edit source]
Through physical examination and report of symptoms
(add differential diagnosis - if relevant)
Outcome Measures[edit | edit source]
add links to outcome measures here (see Outcome Measures Database)
Management / Interventions
[edit | edit source]
Surgery - simple but need training. Special fistula hospitals. Most doctors in low resource settings lack the training or resources to identify and repair fistula
Physical rehabilitation
Education
Psychological support
Physiotherapy Management[edit | edit source]
Pre-op
Post-op
