In developing countries, women who are affected by obstetric fistulae do not necessarily have full agency over their bodies or their households. Rather, their husbands and other family members have control in determining the healthcare that the women receive. For example, a woman's family may refuse medical examinations for the patient by male doctors, but female doctors may be unavailable, thus barring women from prenatal care. Furthermore, many societies believe that women are supposed to suffer in childbirth, thus are less inclined to support maternal health efforts.
Prevention is the key to ending fistulae. UNFPA states that, “Ensuring skilled birth attendance at all births and providing emergency obstetric care for all women who develop complications during delivery would make fistula as rare in developing countries as it is in the industrialized world.” In addition, access to health services and education – including family planning, gender equality, higher living standards, child marriage, and human rights must be addressed to reduce the marginalization of women and girls. Reducing marginalization in these areas could reduce maternal disability and death by at least 20%.
Prevention comes in the form of access to obstetrical care, support from trained health care professionals throughout pregnancy, providing access to family planning, promoting the practice of spacing between births, supporting women in education, and postponing early marriage. Fistula prevention also involves many strategies to educate local communities about the cultural, social, and physiological factors of that condition and contribute to the risk for fistulae. One of these strategies involves organizing community-level awareness campaigns to educate women about prevention methods such as proper hygiene and care during pregnancy and labor. Prevention of prolonged obstructed labor and fistulae should preferably begin as early as possible in each woman's life. For example, improved nutrition and outreach programs to raise awareness about the nutritional needs of children to prevent malnutrition, as well as improve the physical maturity of young mothers, are important fistula prevention strategies. It is also important to ensure access to timely and safe delivery during childbirth: measures include availability and provision of emergency obstetric care, as well as quick and safe cesarean sections for women in obstructed labor. Some organizations train local nurses and midwives to perform emergency cesarean sections to avoid vaginal delivery for young mothers who have underdeveloped pelvises. Midwives located in the local communities where obstetric fistulae are prevalent can contribute to promoting health practices that help prevent future development of obstetric fistulae. NGOs also work with local governments, like the government of Niger, to offer free cesarean sections, further preventing the onset of obstetric fistulae.
Promoting education for girls is also a key factor to preventing fistulae in the long term. Former fistula patients often act as "community fistula advocates" or "ambassadors of hope," a UNFPA-sponsored initiative, to educate the community. These survivors help current patients, educate pregnant mothers, and dispel cultural myths that obstetric fistulae are caused by adultery or evil spirits. Successful ambassador programs are in place in Kenya, Bangladesh, Nigeria, Ghana, Côte d'Ivoire, and Liberia.
Several organizations have developed effective fistula prevention strategies. One, the Tanzanian Midwives Association, works to prevent fistulae by improving clinical healthcare for women, encouraging the delay of early marriages and childbearing years, and helping the local communities to advocate for women's rights.
can be easily diagnosed on ultrasound, vagina is seen filled with blood and uterus is pushed upward. associated hematosalpinx and hematometra may be seen.
Several techniques are used to reduce the risk of tearing, but with little evidence for efficacy. Antenatal digital perineal massage is often advocated, and may reduce the risk of trauma only in nulliparous women. ‘Hands on’ techniques employed by midwives, in which the foetal head is guided through the vagina at a controlled rate have been widely advocated, but their efficacy is unclear. Waterbirth and labouring in water are popular for several reasons, and it has been suggested that by softening the perineum they might reduce the rate of tearing. However, this effect has never been clearly demonstrated.
Cystocele may be mild enough not to result in symptoms that are troubling to a woman. In this case, steps to prevent it from getting worse.These are:
- smoking cessation
- losing weight
- pelvic floor strengthening
- treatment of a chronic cough
- maintaining healthy bowel habits
- eating high fiber foods
- avoiding constipation and straining
In the US, greater than than 200,000 surgeries are performed each year for pelvic organ prolapse and 81% of these are to correct cystocele. Cystocele occurs most frequently compared to the prolapse of other pelvic organs and structure. Cystocele is found to be three times as common as vaginal vault prolapse and twice as often as posterior vaginal wall defects. The incidence of cystocele is around 9 per 100 women-years. The highest incidence of symptoms occurs between ages of 70-79 years old. Based on population growth statistics, the number of women with prolapse will increase by a minimum of 46% by the year 2050 in the US. Surgery to correct prolapse after hysterectomy is 3.6 per 1,000 women-years.
No useful studies have been done to determine whether acupuncture can help people with stress urinary incontinence.
A simple cruciate incision followed by excision of tags of hymen allows drainage of the retained menstrual blood. A thicker transverse vaginal septum can be treated with Z-plasty. A blind vagina will require a partial or complete vaginoplasty. Hematosalpinx may require laprotomy or laparoscopy for removal and reconstruction of affected tube.
Infertility may require assisted reproductive techniques.
Leukorrhea may be caused by sexually transmitted diseases; therefore, treating the STD will help treat the leukorrhea.
Treatment may include antibiotics, such as metronidazole. Other antibiotics common for the treatment of STDs include clindamycin or trinidazole.
Vaginal gas that involves strong odor or fecal matter may be a result of colovaginal fistula, a serious condition involving a tear between the vagina and colon, which can result from surgery, child birth, diseases (such as Crohn's disease), and other causes. This condition can lead to urinary tract infection and other complications. Vaginal gas can also be a symptom of an internal female genital prolapse, a condition most often caused by childbirth.
Puffs or small amounts of air passed into the vaginal cavity during cunnilingus will not cause any known issues, however "forcing" or purposely blowing air at force into the vaginal cavity can cause an air embolism, which in very rare cases can be potentially dangerous for the woman, and if pregnant, for the fetus.
A 2008 study found that over 85% of women having a vaginal birth sustain some form of perineal trauma, and 60-70% receive stitches. A retrospective study of 8,603 vaginal deliveries in 1994 found a third degree tear had been clinically diagnosed in only 50 women (0.6%). However, when the same authors used anal endosonography in a consecutive group of 202 deliveries, there was evidence of third degree tears in 35% of first-time mothers and 44% of mothers with previous children. These numbers are confirmed by other researchers in 1999.
A study by the Agency for Healthcare Research and Quality (AHRQ) found that in 2011, first- and second-degree perineal tear was the most common complicating condition for vaginal deliveries in the U.S. among women covered by either private insurance or Medicaid.
Second-degree perineal laceration rates were higher for women covered by private insurance than for women covered by Medicaid.
Vaginal flatulence is an emission or expulsion of air from the vagina. It may occur during or after sexual intercourse or during other sexual acts, stretching or exercise. The sound is somewhat comparable to flatulence from the anus but does not involve waste gases and thus often does not have a specific odor associated. Slang terms for vaginal flatulence include vart, queef, and fanny fart (mostly British).
Hematometra is usually treated by surgical cervical dilation to drain the blood from the uterus. Other treatments target the underlying cause of the hematometra; for example, a hysteroscopy may be required to resect adhesions that have developed following a previous surgery. If the cause of the hematometra is unclear, a biopsy of endometrial tissue can be taken to test for the presence of a neoplasm (cancer). Antibiotics may be given as prophylaxis against the possibility of infection.
The cause of the bleeding can often be discerned on the basis of the bleeding history, physical examination, and other medical tests as appropriate. The physical examination for evaluating vaginal bleeding typically includes visualization of the cervix with a speculum, a bimanual exam, and a rectovaginal exam. These are focused on finding the source of the bleeding and looking for any abnormalities that could cause bleeding. In addition, the abdomen is examined and palpated to ascertain if the bleeding is abdominal in origin. Typically a pregnancy test is performed as well. If bleeding was excessive or prolonged, a CBC may be useful to check for anemia. Abnormal endometrium may have to be investigated by a hysteroscopy with a biopsy or a dilation and curettage.
In an emergency or acute setting, vaginal bleeding can lead to hypovolemia.
The treatment will be directed at the cause. Hormonal bleeding problems during the reproductive years, if bothersome to the woman, are frequently managed by use of combined oral contraceptive pills.
A Cochrane review found little high quality evidence regarding the treatment of vaginismus in 2012. Specifically it is unclear if systematic desensitisation is better than other measures including nothing.
The Nugent Score is now rarely used by physicians due to the time it takes to read the slides and requires the use of a trained microscopist. A score of 0-10 is generated from combining three other scores. The scores are as follows:
- 0–3 is considered negative for BV
- 4–6 is considered intermediate
- 7+ is considered indicative of BV.
At least 10–20 high power (1000× oil immersion) fields are counted and an average determined.
DNA hybridization testing with Affirm VPIII was compared to the Gram stain using the Nugent criteria. The Affirm VPIII test may be used for the rapid diagnosis of BV in symptomatic women but uses expensive proprietary equipment to read results, and does not detect other pathogens that cause BV, including Prevotella spp, Bacteroides spp, & Mobiluncus spp.
In 2011, the International Federation of Gynaecology and Obstetrics (FIGO) recognized two systems designed to aid research, education, and clinical care of women with abnormal uterine bleeding (AUB) in the reproductive years.
According to Ward and Ogden's qualitative study on the experience of vaginismus (1994), the three most common contributing factors to vaginismus are fear of painful sex; the belief that sex is wrong or shameful (often the case with patients who had a strict religious upbringing); and traumatic early childhood experiences (not necessarily sexual in nature).
People with vaginismus are twice as likely to have a history of childhood sexual interference and held less positive attitudes about their sexuality, whereas no correlation was noted for lack of sexual knowledge or (non-sexual) physical abuse.
Treatment is conservative, mechanical or surgical. Conservative options include behavioral modification and muscle strengthening exercises such as Kegel exercise. Pessaries are a mechanical treatment as they elevate and support the uterus. Surgical options are many and may include a hysterectomy or a uterus-sparing technique such as laparoscopic hysteropexy, sacrohysteropexy or the Manchester operation.
In the case of hysterectomy, the procedure can be accompanied by sacrocolpopexy. This is a mesh-augmented procedure in which the apex of the vagina is attached to the sacrum by a piece of medical mesh material.
A Cochrane Collaboration (2016) review found that sacral colpopexy was associated with lower risk of complications than vaginal interventions, but it was unclear what route of sacral colpopexy should be preferred. No clear conclusion could be reached regarding uterine preserving surgery versus vaginal hysterectomy for uterine prolapse. The evidence does not support use of transvaginal mesh compared to native tissue repair for apical vaginal prolapse. The use of a transvaginal mesh is associated with side effects including pain, infection, and organ perforation. According to the FDA, serious complications are "not rare". A number of class action lawsuits have been filed and settled against several manufacturers of TVM devices.
Although hematometra can often be diagnosed based purely on the patient's history of amenorrhea and cyclic abdominal pain, as well as a palpable pelvic mass on examination, the diagnosis can be confirmed by ultrasound, which will show blood pooled in the uterus and an enlargement of the uterine cavity. A pyelogram or laparoscopy may assist in diagnosing any congenital disorder that is suspected to be the underlying cause of the hematometra.
A physical examination may reveal a mass or distention of the abdomen.
Tests which may be useful for diagnosis include:
- Abdominal x-ray
- Abdominal CT scan
- Contrast enema study
A vaginal cone, also known as a vaginal weight, is a medical device specifically designed and shaped to exercise pelvic floor muscles and help restore proper bladder functions in women with urinary stress incontinence. The device comes with a cone with a string on the outside. Varying weights are placed inside the cone. Starting with the lowest weight, women insert the cone into the vagina, like they would with a tampon. They then contract their pelvic floor muscles to keep the cone from falling out. As their muscles get stronger, the weights can be increased.
Proper treatment will usually relieve the symptoms, at least to some extent.
An alternative is to use a Gram-stained vaginal smear, with the Hay/Ison criteria or the Nugent criteria. The Hay/Ison criteria are defined as follows:
- Grade 1 (Normal): Lactobacillus morphotypes predominate.
- Grade 2 (Intermediate): Mixed flora with some Lactobacilli present, but Gardnerella or Mobiluncus morphotypes also present.
- Grade 3 (Bacterial Vaginosis): Predominantly Gardnerella and/or Mobiluncus morphotypes. Few or absent Lactobacilli. (Hay et al., 1994)
Gardnerella vaginalis is the main culprit in BV. Gardnerella vaginalis is a short rod (coccobacillus). Hence, the presence of clue cells and gram variable coccobacilli are indicative or diagnostic of bacterial vaginosis.
Leukorrhea is also caused by trichomonads, a group of parasitic protozoan, specifically "Trichomonas vaginalis". Common symptoms of this disease are burning sensation, itching and discharge of frothy substance, thick, white or yellow mucous.
