Genitourinary Changes in Pregnancy. Progesterone causes many changes to the genitourinary system. A pregnant woman may experience an increase in the size of the kidneys and ureter due to the increase blood volume and vasculature. Later in pregnancy, the woman might develop physiological hydronephrosis and hydroureter, which are normal. [33]
Generally, diseases outlined within the ICD-10 codes O00-O99 within Chapter XV: Pregnancy, childbirth and the puerperium should be included in this category. v t
Fetal distress, also known as non-reassuring fetal status, is a condition during pregnancy or labor in which the fetus shows signs of inadequate oxygenation. [1] Due to its imprecision, the term "fetal distress" has fallen out of use in American obstetrics. [2] [1] [3] The term "non-reassuring fetal status" has largely replaced it. [4]
In cell biology and pathophysiology, cellular adaptation refers to changes made by a cell in response to adverse or varying environmental changes. The adaptation may be physiologic (normal) or pathologic (abnormal). Morphological adaptations observed at the cellular level include atrophy, hypertrophy, hyperplasia, and metaplasia. [1]
A first-of-its-kind case study has highlighted the ways in which the brain changes throughout pregnancy, including decreases in gray matter volume, and increases in white matter.
On gross pathology, the presence of chorionic villi (left) is diagnostic of products of conception, whereas decidua (right) is not. The diagnosis is based on clinical presentation, quantitative HCG, ultrasound, and pathologic evaluation. A solid, heterogeneous, echogenic mass has a positive predictive value of 80%, but is present in only a ...
The normal hemoglobin types are Hemoglobin A (HbA), which makes up 95–98% of total hemoglobin in adults, Hemoglobin A2 (HbA2), which constitutes 2–3% of total hemoglobin in adults, and Hemoglobin F (HbF), which is the predominant hemoglobin in the fetus during pregnancy, and may persist in small amounts in adults.
Associative prevention mechanisms can be a method of minimising the risk of developing the disease, within early stages of pregnancy. Placental syndromes include pregnancy loss, fetal growth restriction, preeclampsia, preterm delivery, premature rupture of membranes, placental abruption and intrauterine fetal demise.
