A number of medications may be used to control symptoms. NSAIDs can be used to reduce painful menstrual periods. Oral contraceptive pills may be prescribed to reduce uterine bleeding and cramps. Anemia may be treated with iron supplementation.
Levonorgestrel intrauterine devices are effective in limiting menstrual blood flow and improving other symptoms. Side effects are typically few as the levonorgestrel (a progestin) is released in low concentration locally. While most levongestrel-IUD studies concentrated on treatment of women without fibroids a few reported good results specifically for women with fibroids including a substantial regression of fibroids.
Cabergoline in a moderate and well-tolerated dose has been shown in two studies to shrink fibroids effectively. The mechanism of action responsible for how cabergoline shrinks fibroids is unclear.
Ulipristal acetate is a synthetic selective progesterone receptor modulator (SPRM) that has tentative evidence to support its use for presurgical treatment of fibroids with low side-effects. Long-term UPA-treated fibroids have shown volume reduction of about 70%. In some cases UPA alone is used to relieve symptoms without surgery.
Danazol is an effective treatment to shrink fibroids and control symptoms. Its use is limited by unpleasant side effects. Mechanism of action is thought to be antiestrogenic effects. Recent experience indicates that safety and side effect profile can be improved by more cautious dosing.
Gonadotropin-releasing hormone analogs cause temporary regression of fibroids by decreasing estrogen levels. Because of the limitations and side effects of this medication, it is rarely recommended other than for preoperative use to shrink the size of the fibroids and uterus before surgery. It is typically used for a maximum of 6 months or less because after longer use they could cause osteoporosis and other typically postmenopausal complications. The main side effects are transient postmenopausal symptoms. In many cases the fibroids will regrow after cessation of treatment, however, significant benefits may persist for much longer in some cases. Several variations are possible, such as GnRH agonists with add-back regimens intended to decrease the adverse effects of estrogen deficiency. Several add-back regimes are possible, tibolone, raloxifene, progestogens alone, estrogen alone, and combined estrogens and progestogens.
Progesterone antagonists such as mifepristone have been tested, there is evidence that it relieves some symptoms and improves quality of life but because of adverse histological changes that have been observed in several trials it can not be currently recommended outside of research setting. Fibroid growth has recurred after antiprogestin treatment was stopped.
Aromatase inhibitors have been used experimentally to reduce fibroids. The effect is believed to be due partially by lowering systemic estrogen levels and partially by inhibiting locally overexpressed aromatase in fibroids. However, fibroid growth has recurred after treatment was stopped. Experience from experimental aromatase inhibitor treatment of endometriosis indicates that aromatase inhibitors might be particularly useful in combination with a progestogenic ovulation inhibitor.
Most fibroids do not require treatment unless they are causing symptoms. After menopause fibroids shrink and it is unusual for them to cause problems.
Symptomatic uterine fibroids can be treated by:
- medication to control symptoms
- medication aimed at shrinking tumors
- ultrasound fibroid destruction
- myomectomy or radio frequency ablation
- hysterectomy
- uterine artery embolization
In those who have symptoms uterine artery embolization and surgical options have similar outcomes with respect to satisfaction.
Historically, the combination of external-beam radiation therapy (EBRT) has been the most common treatment for vaginal cancer. In early stages of vaginal cancer, surgery also has some benefit. This management and treatment is less effective for those with advanced stages of cancer but works well in early stages with high rates of cure. Advanced vaginal cancer only has a 5-year survival rates of 52.2%, 42.5% and 20.5% for patients with stage II, III and IVa disease. Newer treatments for advanced stages of ovarian have been developed. These utilize concurrent carboplatin plus paclitaxel, EBRT and high-dose-rate interstitial brachytherapy (HDR-ISBT).
When the chance of surgical removal of all cancerous tissue is very low or when the surgery has a chance of damaging the bladder, vagina or bowel, radiation therapy is used. When a tumor is less than 4 cm in diameter, radiation therapy provides excellent results. In these instances, the 5-year survival rate is greater than 80%. Treatments are individualized due to the rarity of vaginal cancer studies.
Uterine fibroids can be treated with the same methods like sporadic uterine fibroids including antihormonal treatment, surgery or embolisation. Substantially elevated risk of progression to or independent development of uterine leiomyosarcoma has been reported which may influence treatment methods.
The predisposition to renal cell cancer calls for screening and, if necessary, urological management.
The skin lesions may be difficult to treat as they tend to recur after excision or destructive treatment. Drugs which affect smooth muscle contraction, such as doxazosin, nitroglycerine, nifedipine and phenoxybenzamine, may provide pain relief.
Topical lidocaine patches have been reported to decrease in severity and frequency of pain cutaneous leiomyomas.
Therapy is based on staging and patient condition and utilizes one or more of the following approaches.
Surgery is the mainstay of therapy if feasible involving total abdominal hysterectomy with bilateral salpingo-oophorectomy. Other approaches include radiation therapy, chemotherapy, and hormonal therapy.
Prognosis is relatively poor.
Surgical intervention depends on the extent of the individual problem. With a didelphic uterus surgery is not usually recommended.
A uterine septum can be resected in a simple out-patient procedure that combines laparoscopy and hysteroscopy. This procedure greatly decreases the rate of miscarriage for women with this anomaly.
A septum can be resected with surgery. Hysteroscopic removal of a uterine septum is generally the preferred method, as the intervention is relatively minor and safe in experienced hands. A follow-up imaging study should demonstrate the removal of the septum.
Tactile cold scissor metroplasty was described as a back technique for hysteroscopic challenges that interfere with proper visualization or uterine distention
It is not considered necessary to remove a septum that has not caused problems, especially in women who are not considering pregnancy. There is controversy over whether a septum should be removed prophylactically to reduce the risk of pregnancy loss prior to a pregnancy or infertility treatment.
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.
The first line of therapy after diagnosis typically involves the administration of the combined oral contraceptive pill, medroxyprogesterone acetate or a gonadotropin-releasing hormone agonist to suppress menstruation and thereby relieve pain. Surgically, cervical agenesis has historically been treated through hysterectomy (removal of the uterus) to relieve symptoms caused by hematocolpos (the accumulation of menstrual fluid in the vagina). Other surgical methods of management involve the creation of an anastomotic connection between the uterus and vagina by neovaginoplasty or recanalization of the cervix. Outcomes in these cases are generally poor, since the natural functions of the cervix—such as mucus production and providing a barrier against ascending infection—cannot be replicated. Furthermore, the success rate of uterovaginal anastomosis is less than 50% and most patients require multiple surgeries while many develop cervical stenotis. Despite this, several pregnancies have been reported in women with cervical agenesis who underwent surgical treatment.
Severe acute bleeding, such as caused by ectopic pregnancy and post-partum hemorrhage, leads to hypovolemia (the depletion of blood from the circulation), progressing to shock. This is a medical emergency and requires hospital attendance and intravenous fluids, usually followed by blood transfusion. Once the circulating volume has been restored, investigations are performed to identify the source of bleeding and address it. Uncontrolled life-threatening bleeding may require uterine artery embolization (occlusion of the blood vessels supplying the uterus), laparotomy (surgical opening of the abdomen), occasionally leading to hysterectomy (removal of the uterus) as a last resort.
A possible complication from protracted vaginal blood loss is iron deficiency anemia, which can develop insidiously. Eliminating the cause will resolve the anemia, although some women require iron supplements or blood transfusions to improve the anemia.
The disease used to be uniformly fatal, with a 5-year survival rate between 10 and 35%. As a result, treatment was radical surgery. New multidrug chemotherapy regimens with or without radiation therapy are now used in combination with less radical surgery with good results, although outcome data are not yet available.
A review indicated the effectiveness of transdermal nitroglycerin.
Treatment options range from no treatment for a mild cystocele to surgery for a more extensive cystocele. If a cystocele is not bothersome, the clinician may only recommend avoiding heavy lifting or straining that could cause the cystocele to worsen. If symptoms are moderately bothersome, the doctor may recommend a pessary, a device placed in the vagina to hold the bladder in place. Treatment can consist of a combination of non-surgical and surgical management. Treatment choice is also related to age, desire to have children, severity of impairment, desire to continue sexual intercourse and other diseases that a woman may have.
Cystocele is often treated by non-surgical means:
- Pessary - This is a removable device inserted into the vagina to support the anterior vaginal wall. Pessaries come in many different shapes and sizes. There are sometimes complications with the use of a pessary.
- Pelvic floor muscle therapy - Pelvic floor exercises to strengthen vaginal support can be of benefit. Specialized physical therapy can be prescribed to help strengthen the pelvic floor muscles.
- Dietary changes - Ingesting high fiber foods will aid in promoting bowel movements.
Use of hormonal birth control may improve symptoms of primary dysmenorrhea. A 2009 systematic review however found limited evidence that the birth control pill, containing low doses or medium doses of oestrogen, reduces pain associated with dysmenorrhea. In addition, no differences between different birth control pill preparations were found.
Norplant and Depo-provera are also effective, since these methods often induce amenorrhea. The intrauterine system (Mirena IUD) may be useful in reducing symptoms.
There are several methods of treatment for individuals with vaginal atresia. The first method of treatment that is recommended would be self-dilation of the vagina. A doctor may first recommend that the patient first attempts to create a vagina themselves through the process self-dilation. The self dilation technique consists of using vaginal dilators, which are small round tubes that vary in size and are similar in size and shape to tampons. Vaginal dilators may be pressed alongside the vaginal area on a regular basis in order to further open the vaginal canal. Frank's procedure is a technique that used a progressive series of vaginal dilators that are inserted into the dimple of the vagina while using pressure. This will widen any space that exists between the bladder and the rectum. Frank's procedure can be performed directly by the patient, therefore requiring no surgery or anesthesia. The procedure/technique can take months to complete, with regular compliance necessary. The overall success rate for females who use Frank's procedure is 80%. If this procedure does not work, then surgery would be the next method of treatment. Another alternative form of treatment would be surgery, or the creation of a new vagina.
The following treatments are typically recommended:
- Intravaginal agents: butoconazole, clotrimazole, miconazole, nystatin, tioconazole, terconazole. Candidal vulvovaginitis in pregnancy should be treated with intravaginal clotrimazole or nystatin for at least 7 days. All are more or less equally effective.
- By mouth: fluconazole as a single dose. For severe disease another dose after 3 days may be used.
Short-course topical formulations (i.e., single dose and regimens of 1–3 days) effectively treat uncomplicated candidal vulvovaginitis. The topically applied azole drugs are more effective than nystatin. Treatment with azoles results in relief of symptoms and negative cultures in 80–90% of patients who complete therapy.
The creams and suppositories in this regimen are oil-based and might weaken latex condoms and diaphragms. Treatment for vagina thrush using antifungal medication is ineffective in up to 20% of cases. Treatment for thrush is considered to have failed if the symptoms do not clear within 7–14 days. There are a number of reasons for treatment failure. For example, if the infection is a different kind, such as bacterial vaginosis (the most common cause of abnormal vaginal discharge), rather than thrush.
In postmenopausal bleeding, guidelines from the United States consider transvaginal ultrasonography to be an appropriate first-line procedure to identify which women are at higher risk of endometrial cancer. A cut-off threshold of 3 mm or less of endometrial thickness should be used for in women with postmenopausal bleeding in the following cases:
- Not having used hormone replacement therapy for a year or more
- Usage of continuous hormone replacement therapy consisting of both an estrogen and a progestagen
A cut-off threshold of 5 mm or less should be used for women on sequential hormone replacement therapy consisting both of an estrogen and a progestagen.
It the endometrial thickness equals the cut-off threshold or is thinner, and the ultrasonography is otherwise reassuring, no further action need be taken. Further investigations should be carried out if symptoms recur.
If the ultrasonography is not reassuring, hysteroscopy and endometrial biopsy should be performed. The biopsy may be obtained either by curettage at the same time as inpatient or outpatient hysteroscopy, or by using an endometrium sampling device such as a pipelle which can practically be done directly after the ultrasonography.
Vaginal prolapses are treated according to the severity of symptoms. They can be treated:
- With conservative measures (changes in diet and fitness, Kegel exercises, pelvic floor physical therapy.
- With a pessary, a rubber or silicon device fitted to the patient which is inserted into the vagina and may be retained for up to several months. Pessaries are a good choice of treatment for women who wish to maintain fertility, are poor surgical candidates, or who may not be able to attend physical therapy. Pessaries require a provider to fit the device, but most can be removed, cleaned, and replaced by the woman herself. Pessaries should be offered to women considering surgery as a non-surgical alternative.
- With surgery (for example native tissue repair, biological graft repair, absorbable and non-absorbable mesh repair, colpopexy, colpocleisis). Surgery is used to treat symptoms such as bowel or urinary problems, pain, or a prolapse sensation. According to the Cochrane Collaboration review (2016) current evidence does not support the use of transvaginal surgical mesh repair compared with native tissue repair for anterior compartment prolapse owing to increased morbidity. Safety and efficacy of many newer meshes is unknown. The use of a transvaginal mesh in treating vaginal prolapses 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.
Treatment is typically with the antibiotics metronidazole or clindamycin. They can be either given by mouth or applied inside the vagina. About 10% to 15% of people, however, do not improve with the first course of antibiotics and recurrence rates of up to 80% have been documented. Recurrence rates are increased with sexual activity with the same pre-/posttreatment partner and inconsistent condom use although estrogen-containing contraceptives decrease recurrence. When clindamycin is given to pregnant women symptomatic with BV before 22 weeks of gestation the risk of pre-term birth before 37 weeks of gestation is lower.
Other antibiotics that may work include macrolides, lincosamides, nitroimidazoles, and penicillins.
Bacterial vaginosis is not considered a sexually transmitted infection, and treatment of a male sexual partner of a woman with bacterial vaginosis is not recommended.
Up to 40% of women seek alternatives to treat vaginal yeast infection. Example products are herbal preparations, probiotics and vaginal acidifying agents. Other alternative treatment approaches include switching contraceptive, treatment of the sexual partner and gentian violet. However, the effectiveness of such treatments has not received much study.
Probiotics (either as pills or as yogurt) do not appear to decrease the rate of occurrence of vaginal yeast infections. No benefit has been found for active infections. Example probiotics purported to treat and prevent candida infections are Lactobacillus fermentum RC-14, Lactobacillus fermentum B-54, Lactobacillus rhamnosus GR-1, Lactobacillus rhamnosus GG and Lactobacillus acidophilus.
There is no evidence to support the use of special cleansing diets and colonic hydrotherapy for prevention.
Surgery can be done to correct rectocele when symptoms continue despite the use of non-surgical management, and are significant enough to interfere with activities of daily living.
Surgery to correct the rectocele may involve the reattachment of the muscles that previously supported the pelvic floor. Another procedure is posterior colporrhaphy, which involves suturing of vaginal tissue. Surgery may also involve insertion of a supporting mesh (that is, a patch). There are also surgical techniques directed at repairing or strengthening the rectovaginal septum, rather than simple excision or plication of vaginal skin which provides no support. Both gynecologists and colorectal surgeons can address this problem. Potential complications of surgical correction of a rectocele include bleeding, infection, dyspareunia (pain during intercourse), as well as recurrence or even worsening of the rectocele symptoms. The use of synthetic or biologic grafts has been questioned.
A 2009 Cochrane review found tentative but insufficient evidence for probiotics as a treatment for BV. A 2014 review reached the same conclusion. A 2013 review found some evidence supporting the use of probiotics during pregnancy. The preferred probiotics for BV are those containing high doses of lactobacilli (around 10 ) given in the vagina. Intravaginal administration is preferred to taking them by mouth. Prolonged repetitive courses of treatment appear to be more promising than short courses.
In order to facilitate sexual intercourse, the main treatments are self-dilation methods (using intra-vaginal cylinders of increasing size) and surgical vaginoplasty to lengthen the vagina.
Self-dilation has a high success rate, estimated at 75%, and is usually the first-line treatment due to low surgical invasiveness. Overall, the complication rates are significantly lower with dilation than with vaginoplasty.
Surgery is indicated when there is inability or reluctance to perform self-dilation, or where it is performed but with failed result. One appropriate surgical variant is the "Vecchietti technique". In this procedure, an olive-shaped pressure device is pressed towards the potential vaginal space by a thread that goes through the skin, behind the urinary bladder and pubic bone and exits the skin in the hypogastrium, where it is attached to a plate that provides counter-traction. Vaginoplasty can also be performed using a skin graft or an intestinal graft. Traction vaginoplasty such as the "Vecchietti technique" seems to have the highest success rates both anatomically (99%) and functionally (96%), whereas skin graft procedures and intestinal procedures have the lowest successful outcomes (83–95%).
After vaginoplasty, available evidence suggests that continued self-dilation is needed to maintain patency in periods of coital inactivity.
There is no cure available for individuals with Bardet-Biedl Syndrome, however there are methods of treatment for some of the signs and symptoms within each individual. Corrective surgery of malformation related to the disorder may be an option for treatment. Genetic counseling is also something that could be beneficial to families with this disorder.
