Uterine hyperplasia, or enlarged uterus, is a medical symptom in which the volume and size of the uterus in a female is abnormally high. It can be a symptom of medical conditions such as adenomyosis , uterine fibroids , ovarian cysts , and endometrial cancer .
Fundal height, or McDonald's rule, is a measure of the size of the uterus used to assess fetal growth and development during pregnancy. It is measured from the top of the mother's uterus to the top of the mother's pubic symphysis.
[1] [2] [3] Macrosomia is a similar term that describes excessive birth weight, but refers to an absolute measurement, regardless of gestational age. [4] Typically the threshold for diagnosing macrosomia is a body weight between 4,000 and 4,500 grams (8 lb 13 oz and 9 lb 15 oz), or more, measured at birth, but there are difficulties reaching a ...
Adenomyosis is a medical condition characterized by the growth of cells that proliferate on the inside of the uterus (endometrium) atypically located among the cells of the uterine wall , [2] as a result, thickening of the uterus occurs. As well as being misplaced in patients with this condition, endometrial tissue is completely functional.
A bimanual examination during early pregnancy will reveal that the uterus is enlarged, softened and globular; the external os may be dilated, but the internal os is typically closed. [24] The structures adjacent to the uterus will be assessed, along with the size and shape of the bony pelvis. [24]
The gestational sac is spherical in shape, and is usually located in the upper part (fundus) of the uterus.By approximately nine weeks of gestational age, due to folding of the trilaminar germ disc, the amniotic sac expands and occupy the majority of the volume of the gestational sac, eventually reducing the extraembryonic coelom (the gestational sac or the chorionic cavity) to a thin layer ...
Endometrial hyperplasia is a condition of excessive proliferation of the cells of the endometrium, or inner lining of the uterus.. Most cases of endometrial hyperplasia result from high levels of estrogens, combined with insufficient levels of the progesterone-like hormones which ordinarily counteract estrogen's proliferative effects on this tissue.
Montevideo units are a method of measuring uterine performance during labor. They were created in 1949 by two physicians, Roberto Caldeyro-Barcia and Hermogenes Alvarez, from Montevideo, Uruguay. They are exactly equal to 1 mmHg within 10 minutes.
