Double uterus is the condition where the uterus spilts into two different tubes. As the fetus develops, the tubes normally join to create one larger, hollow organ the uterus. Sometimes, however, the tubes don't join completely. Instead, each one develops into a separate structure. This condition is called double uterus (uterus didelphys). A double uterus may have one opening (cervix) into one vagina, or each uterine cavity may have a cervix. There may even be two vaginas.
Each cavity in a double uterus often leads to its own cervix. Some women with a double uterus also have a duplicate or divided vagina. Possible signs and symptoms may include:
• Unusual pressure or cramping pain before or during a menstrual period
• Abnormal bleeding during a period, such as blood flow despite the use of a tampon Double uterus may be diagnosed during a routine pelvic exam when your doctor observes a double cervix or feels an abnormally shaped uterus.
If doctor suspects an abnormality, he or she may recommend any of the following tests:
• MRI scan
Surgery to unite a double uterus is rarely done although surgery may help patient to sustain a pregnancy if she has a partial division within her uterus and no other medical explanation for a previous pregnancy loss.
It results from failed ductal fusion that occurs between the 12th and 16th week of pregnancy and is characterised by two symmetric, widely divergent uterine horns and two cervices. The uterine volume in each duplicated segment is reduced. As with most uterine anatomical anomalies, there is an increased incidence of fertility issues, and Müllerian abnormalities in general are over represented in infertile women. The chance of seeing a pregnancy to term is significantly reduced, down to only 20%, with a third of pregnancies ending in abortion and over half in premature deliveries. Only 40% of pregnancies resulted in living children.
