Ultrasound involves a probe that is placed near a structure and uses the transmission of ultrasound waves through a structure to produce images, after computer processing. [1] Ultrasound of the urinary tract is performed by a probe placed on the abdominal wall, called a transducer. [1] This occurs while a person is lying down. [1]
The anomaly scan, also sometimes called the anatomy scan, 20-week ultrasound, or level 2 ultrasound, evaluates anatomic structures of the fetus, placenta, and maternal pelvic organs. This scan is an important and common component of routine prenatal care . [ 1 ]
A transvaginal ultrasound showing a retroverted uterus during pregnancy. The cervix lies posteriorly to the urinary bladder, and the uterus normally extends superiorly from it, but the direction of the body of the fetus reveals that the uterus extends backwards. Specialty: Gynaecology: Treatment: Exercise. Vaginal pessary. Manual repositioning ...
Bladder outlet obstruction can be identified during routine prenatal ultrasonography as dilation of the fetal urinary tract [3] and decreased amniotic fluid levels. If dilation of the fetal urinary tract is suspected during pregnancy, an ultrasound of the infant's kidneys and bladder should be obtained after birth.
Manual placenta removal is the evacuation of the placenta from the uterus by hand. [4] It is usually carried out under anesthesia or more rarely, under sedation and analgesia . A hand is inserted through the vagina and cervix into the uterine cavity and the placenta is detached from the uterine wall and then removed manually.
The fetal circulation is composed of the placenta, umbilical blood vessels encapsulated by the umbilical cord, heart and systemic blood vessels. A major difference between the fetal circulation and postnatal circulation is that the lungs are not used during the fetal stage resulting in the presence of shunts to move oxygenated blood and ...
As the bladder reaches capacity, patients typically feel some mild discomfort and the urge to urinate. [citation needed] The time from insertion of the cystoscope to removal may be only a few minutes, or it may be longer if the physician finds a stone and decides to remove it, or in cases where a biopsy is required. Taking a biopsy (a small ...
Transvaginal ultrasonography – Ultrasound is performed through the vagina; Transabdominal ultrasonography – Ultrasound is performed across the abdominal wall or through the abdominal cavity; In normal state, each body tissue type, such as liver, spleen or kidney, has a unique echogenicity. Fortunately, gestational sac, yolk sac and embryo ...
