Obstetric fistula


Obstetric fistula is a medical condition in which a hole develops in the birth canal as a result of childbirth. This can be between the vagina and rectum, ureter, or bladder. It can result in incontinence of urine or feces. Complications may include depression, infertility, and social isolation.
Risk factors include obstructed labor, poor access to medical care, malnutrition, and teenage pregnancy. The underlying mechanism is poor blood flow to the affected area for a prolonged period of time. Diagnosis is generally based on symptoms and may be supported by use of methylene blue.
Obstetric fistulae are almost entirely preventable with appropriate use of cesarean section. Treatment is typically by surgery. If treated early, the use of a urinary catheter may help with healing. Counseling may also be useful. An estimated 2 million people in sub-Saharan Africa, Asia, the Arab region, and Latin America have the condition, with about 75,000 new cases developing a year. It occurs very rarely in the developed world and is considered a disease of poverty.

Signs and symptoms

Symptoms of obstetric fistula include:
Other effects of obstetric fistulae include stillborn babies due to prolonged labor, which happens 85% to 100% of the time, severe ulcerations of the vaginal tract, "foot drop", which is the paralysis of the lower limbs caused by nerve damage, making it impossible to walk, infection of the fistula forming an abscess, and up to two-thirds of sufferers become amenorrhoeic.
Obstetric fistulae have far-reaching physical, social, economic, and psychological consequences for the women affected. According to UNFPA, "Due to the prolonged obstructed labour, the baby almost inevitably dies, and the parent is left with chronic incontinence. Unable to control the flow of urine or faeces, or both, they may be abandoned by their spouse and family and ostracized by their community. Without treatment, their prospects for work and family life are virtually nonexistent."

Physical

The most direct consequence of an obstetric fistula is the constant leakage of urine, feces, and blood as a result of a hole that forms between the vagina and bladder or rectum. This leaking has both physical and societal penalties. The acid in the urine, feces, and blood causes severe burn wounds on the legs from the continuous dripping. Nerve damage that can result from the leaking can cause women to struggle with walking and eventually lose mobility. In an attempt to avoid the dripping, women limit their intake of water and liquid, which can ultimately lead to dangerous cases of dehydration. Ulceration and infections can persist, as well as kidney disease and kidney failure, which can each lead to death. Further, only a quarter of women who develop a fistula in their first birth are able to have a living baby, and therefore have minuscule chances of conceiving a healthy baby later on. Some, due to obstetric fistulae and other complications from childbirth, do not survive.

Social

Physical consequences of obstetric fistulae lead to severe sociocultural stigmatization for various reasons. For example, in Burkina Faso, most citizens do not believe an obstetric fistula to be a medical condition, but as a divine punishment or a curse for disloyal or disrespectful behavior. Other sub-Saharan cultures view offspring as an indicator of a family's wealth. A woman who is unable to successfully produce children as assets for her family is believed to make her and her family socially and economically inferior. A patient's incontinence and pain also render her unable to perform household chores and childrearing as a wife and as a mother, thus devaluing her. Other misconceptions about obstetric fistulae are that they are caused by venereal diseases or are divine punishment for sexual misconduct.
As a result, many girls are divorced or abandoned by their husbands and partners, disowned by family, ridiculed by friends, and even isolated by health workers. Divorce rates for women who have an obstetric fistula range from 50% to as high as 89%. Now marginalized members of society, girls are forced to live on the edges of their villages and towns, often in isolation in a hut where they will likely die from starvation or an infection in the birth canal. The unavoidable odor is viewed as offensive, thus their removal from society is seen as essential. Accounts of women who develop obstetric fistulae proclaim that their lives have been reduced to the leaking of urine, feces, and blood because they are no longer capable or allowed to participate in traditional activities, including the duties of wife and mother. Because such consequences highly stigmatize and marginalize the woman, the intense loneliness and shame can lead to clinical depression and suicidal thoughts. Some women have formed small groups and resorted to walking to seek medical help, where their characteristic odor makes them a target for sub-Saharan predatory wildlife, further endangering their lives. This trip can take on average 12 hours to complete. Moreover, women are sometimes forced to turn to commercial sex work as a means of survival because the extreme poverty and social isolation that result from obstetric fistulae eliminate all other income opportunities. With only 7.5% of women with fistulae able to access treatment, the vast majority of women end up with the consequences of obstructed and prolonged labor simply because options and access to help is so limited.

Psychological

Some common psychological consequences that women with a fistula face are the despair from losing their child, the humiliation from their smell, and inability to perform their family roles. Additionally, a fear of developing another fistula in future pregnancies exists.
Obstetric fistula is not only debilitating physically, but emotionally. A woman is presented with an array of psychological trauma that she must oftentimes deal with herself unless provided with ample resources. Oftentimes ostracized by her community, a woman with obstetric fistula tends to face these issues on her own. In a study of The lived experience of Malawian women with obstetric fistula, the immense psychological trauma is addressed: "For these women, internalizing this constant struggle leads to psychological morbidity." It was striking how many women discussed constant sadness and giving up hope in their interviews."
Although the psychological impacts center around the woman experiencing the fistula, others around them, and especially loved ones, feel the impact as well. The same study references this: "This attitude was often shared by their family members, both husbands and female relatives."
Women with obstetric fistula face severe mental health issues. Among women with obstetric fistula from Bangladesh and Ethiopia 97% screened positive for potential mental health dysfunctions and about 30% had major depression.

Risk factors

In less-developed countries, obstetric fistulae usually develop as a result of prolonged labor when a cesarean section cannot be obtained. Over the course of the three to five days of labor, the unborn child presses against the mother's vagina very tightly, cutting off blood flow to the surrounding tissues between the vagina and the rectum and between the vagina and the bladder, causing the tissues to disintegrate and rot away.
Obstetric fistulae can also be caused by poorly performed abortions, and pelvic fracture, cancer, or radiation therapy targeted at the pelvic area, inflammatory bowel disease. Other potential causes for the development of obstetric fistulae are sexual abuse and rape, especially in conflict/postconflict areas, and other trauma, such as surgical trauma.
In the developed world, such as the US, the primary cause of obstetric fistulae, particularly rectovaginal fistulae, is the use of episiotomy and forceps. Primary risk factors include early or closely spaced pregnancies and lack of access to emergency obstetric care. For example, a 1983 study in Nigeria found that 54.8% of the women affected were under 20 years of age, and 64.4% gave birth at home or in poorly equipped local clinics. When available at all, cesarean sections and other medical interventions are usually not performed until after tissue damage has already been done.
Social, political, and economic causes that indirectly lead to the development of obstetric fistulae concern issues of poverty, malnutrition, lack of education, early marriage and childbirth, the role and status of women in developing countries, harmful traditional practices, sexual violence, and lack of good quality or accessible maternal and health care.

Poverty

is the main indirect cause of obstetric fistulae around the world. As obstructed labor and obstetric fistulae account for 8% of maternal deaths worldwide and "a 60-fold difference in gross national product per person shows up as a 120-fold difference in maternal mortality ratio," impoverished countries produce higher maternal mortality rates and thus higher obstetric fistula rates. Furthermore, impoverished countries not only have low incomes, but also lack adequate infrastructure, trained and educated professionals, resources, and a centralized government that exist in developed nations to effectively eradicate obstetric fistulae.
According to UNFPA, "Generally accepted estimates suggest that 2.0-3.5 million women live with obstetric fistulae in the developing world, and between 50,000 and 100,000 new cases develop each year. All but eliminated from the developed world, obstetric fistula continues to affect the poorest of the poor: women and girls living in some of the most resource-starved remote regions in the world."
