The uterus or womb is the organ in the reproductive system of most female mammals, including humans, that accommodates the embryonic and fetal development of one or more embryos until birth. The uterus is a hormone-responsive sex organ that contains glands in its lining that secrete uterine milk for embryonic nourishment.
Hysterectomy is the partial or total surgical removal of the uterus. It may also involve removal of the cervix, ovaries (oophorectomy), Fallopian tubes (salpingectomy), and other surrounding structures. Partial hysterectomies allow for hormone regulation while total hysterectomies do not.
A pessary is a prosthetic device inserted into the vagina for structural and pharmaceutical purposes. It is most commonly used to treat stress urinary incontinence to stop urinary leakage and to treat pelvic organ prolapse to maintain the location of organs in the pelvic region. It can also be used to administer medications locally in the vagina or as a method of contraception.
A rectal prolapse occurs when walls of the rectum have prolapsed to such a degree that they protrude out of the anus and are visible outside the body. However, most researchers agree that there are 3 to 5 different types of rectal prolapse, depending on whether the prolapsed section is visible externally, and whether the full or only partial thickness of the rectal wall is involved.
The pelvic floor or pelvic diaphragm is a muscular partition separating the pelvic cavity (above), and perineal region (below). It is formed by the levator ani muscle and coccygeus muscle, and associated connective tissue.
In gynecology, a rectocele or posterior vaginal wall prolapse results when the rectum bulges (herniates) into the vagina. Two common causes of this defect are childbirth and hysterectomy. Rectocele also tends to occur with other forms of pelvic organ prolapse, such as enterocele, sigmoidocele and cystocele.
Umbilical cord prolapse is when the umbilical cord comes out of the uterus with or before the presenting part of the baby. The concern with cord prolapse is that pressure on the cord from the baby will compromise blood flow to the baby. It usually occurs during labor but can occur anytime after the rupture of membranes.
The cystocele, also known as a prolapsed bladder, is a medical condition in which a woman's bladder bulges into her vagina. Some may have no symptoms. Others may have trouble starting urination, urinary incontinence, or frequent urination. Complications may include recurrent urinary tract infections and urinary retention. Cystocele and a prolapsed urethra often occur together and is called a cystourethrocele. Cystocele can negatively affect quality of life.
Pelvic organ prolapse (POP) is characterized by descent of pelvic organs from their normal positions into the vagina. In women, the condition usually occurs when the pelvic floor collapses after gynecological cancer treatment, childbirth or heavy lifting. Injury incurred to fascia membranes and other connective structures can result in cystocele, rectocele or both. Treatment can involve dietary and lifestyle changes, physical therapy, or surgery.
Pelvic exenteration is a radical surgical treatment that removes all organs from a person's pelvic cavity. It is used to treat certain advanced or recurrent cancers. The urinary bladder, urethra, rectum, and anus are removed. In women, the vagina, cervix, uterus, Fallopian tubes, ovaries and, in some cases, the vulva are removed. In men, the prostate is removed. The procedure leaves the person with a permanent colostomy and urinary diversion.
Vaginectomy is a surgery to remove all or part of the vagina. It is one form of treatment for individuals with vaginal cancer or rectal cancer that is used to remove tissue with cancerous cells. It can also be used in gender affirmation surgery. Some people born with a vagina who identify as trans men or as nonbinary may choose vaginectomy in conjunction with other surgeries to make the clitoris more penis-like (metoidioplasty), construct of a full-size penis (phalloplasty), or create a relatively smooth, featureless genital area.
Uterine prolapse is a form of pelvic organ prolapse in which the uterus and a portion of the upper vagina protrude into the vaginal canal and, in severe cases, through the opening of the vagina. It is most often caused by injury or damage to structures that hold the uterus in place within the pelvic cavity. Symptoms may include vaginal fullness, pain with sexual intercourse, difficulty urinating, and urinary incontinence. Risk factors include older age, pregnancy, vaginal childbirth, obesity, chronic constipation, and chronic cough. Prevalence, based on physical exam alone, is estimated to be approximately 14%.
A pelvic examination is the physical examination of the external and internal female pelvic organs. It is frequently used in gynecology for the evaluation of symptoms affecting the female reproductive and urinary tract, such as pain, bleeding, discharge, urinary incontinence, or trauma. It can also be used to assess a woman's anatomy in preparation for procedures. The exam can be done awake in the clinic and emergency department, or under anesthesia in the operating room. The most commonly performed components of the exam are 1) the external exam, to evaluate the external genitalia 2) the internal exam with palpation to examine the uterus, ovaries, and fallopian tubes, and 3) the internal exam using the speculum to visualize the vaginal walls and cervix. During the pelvic exam, sample of cells and fluids may be collected to screen for sexually transmitted infections or cancer.
The rectum is the final straight portion of the large intestine in humans and some other mammals, and the gut in others. The adult human rectum is about 12 centimetres (4.7 in) long, and begins at the rectosigmoid junction at the level of the third sacral vertebra or the sacral promontory depending upon what definition is used. Its diameter is similar to that of the sigmoid colon at its commencement, but it is dilated near its termination, forming the rectal ampulla. It terminates at the level of the anorectal ring or the dentate line, again depending upon which definition is used. In humans, the rectum is followed by the anal canal which is about 4 centimetres (1.6 in) long, before the gastrointestinal tract terminates at the anal verge. The word rectum comes from the Latin rectumintestinum, meaning straight intestine.
An obstetric labor complication is a difficulty or abnormality that arises during the process of labor or delivery.
Obstructed defecation syndrome is a major cause of functional constipation, of which it is considered a subtype. It is characterized by difficult and/or incomplete emptying of the rectum with or without an actual reduction in the number of bowel movements per week. Normal definitions of functional constipation include infrequent bowel movements and hard stools. In contrast, ODS may occur with frequent bowel movements and even with soft stools, and the colonic transit time may be normal, but delayed in the rectum and sigmoid colon.
Sigmoidocele refers to a condition where the sigmoid colon descends (prolapses) into the lower pelvic cavity. This can obstruct the rectum and cause symptoms of obstructed defecation.
A urogenital fistula is an abnormal tract that exists between the urinary tract and bladder, ureters, or urethra. A urogenital fistula can occur between any of the organs and structures of the pelvic region. A fistula allows urine to continually exit through and out the urogenital tract. This can result in significant disability, interference with sexual activity, and other physical health issues, the effects of which may in turn have a negative impact on mental or emotional state, including an increase in social isolation. Urogenital fistulas vary in etiology. Fistulas are usually caused by injury or surgery, but they can also result from malignancy, infection, prolonged and obstructed labor and deliver in childbirth, hysterectomy, radiation therapy or inflammation. Of the fistulas that develop from difficult childbirth, 97 percent occur in developing countries. Congenital urogenital fistulas are rare; only ten cases have been documented. Abnormal passageways can also exist between the vagina and the organs of the gastrointestinal system, and these may also be termed fistulas.
The vaginal support structures are those muscles, bones, ligaments, tendons, membranes and fascia, of the pelvic floor that maintain the position of the vagina within the pelvic cavity and allow the normal functioning of the vagina and other reproductive structures in the female. Defects or injuries to these support structures in the pelvic floor leads to pelvic organ prolapse. Anatomical and congenital variations of vaginal support structures can predispose a woman to further dysfunction and prolapse later in life. The urethra is part of the anterior wall of the vagina and damage to the support structures there can lead to incontinence and urinary retention.
Transvaginal mesh, also known as vaginal mesh implant, is a net-like surgical tool that is used to treat pelvic organ prolapse (POP) and stress urinary incontinence (SUI) among female patients. The surgical mesh is placed transvaginally to reconstruct weakened pelvic muscle walls and to support the urethra or bladder.
