To diagnose the rare primary abdominal pregnancy, Studdiford's criteria need to be fulfilled: tubes and ovaries should be normal, there is no abnormal connection between the uterus and the abdominal cavity, and the pregnancy is related solely to the peritoneal surface without signs that there was a tubal pregnancy first.
The main causes of obstructed labour include a large or abnormally positioned baby, a small pelvis, and problems with the birth canal. [2] Both the size and the position of the fetus can lead to obstructed labor. Abnormal positioning includes shoulder dystocia where the anterior shoulder does not pass easily below the pubic bone. [2]
Those conditions, but not the position of the uterus itself, can reduce fertility in some cases. [6] A tipped uterus will usually move to the middle of the pelvis during the 10th to 12th week of pregnancy. Rarely (1 in 3,000 to 8,000 pregnancies), a retroverted uterus will cause painful and difficult urination and can cause severe urinary ...
A uterus is a muscular organ in the female pelvis that holds and nourishes the fetus during pregnancy. "In most women, the uterus is positioned forward," Greves says. Meaning, it's tilted a little ...
Signs and symptoms of preeclampsia can include swelling, protein in the urine, headaches, vomiting, and abnormal labs that assess kidney and liver function, some of which may be considered severe preeclampsia or eclampsia. [11] Post-term pregnancy; Breathing problems; Anemia; Abnormal position and presentation of the fetus; Multiple births ...
The exact cause of placenta previa is unknown. It is hypothesized to be related to abnormal vascularisation of the endometrium caused by scarring or atrophy from previous trauma, surgery, or infection. These factors may reduce differential growth of lower segment, resulting in less upward shift in placental position as pregnancy advances. [11]
A pregnancy not in the uterus [34] The combination of a positive pregnancy test and the presence of what appears to be a normal intrauterine pregnancy does not exclude an ectopic pregnancy, since there may be either a heterotopic pregnancy or a "pseudosac", which is a collection of within the endometrial cavity that may be seen in up to 20% of ...
The piriform (pear-shaped) morphology of the uterus has been given as the major cause for the finding that most singletons favor the cephalic presentation at term. [1] The fundus is larger and thus a fetus will adapt its position so that the bulkier and more movable podalic pole makes use of it, while the head moves to the opposite site.
