An abdominal ultrasound is a procedure that is conducted to visualize the internal organs of the abdomen and the pelvic region as well. Ultrasounds are also used in techniques like amniocentesis and paracentesis as guides to the inserting of a tube or syringe for drainage of fluids. Using ultrasound as an aiming technology is also used in the treatment of gall stones and kidney stones. Abdominal ultrasounds are also used to visualize uterine structures when a woman does not want to perform a trans-vaginal scan. These can be equally effective in locating uterine problems like cysts and ectopic pregnancies.
The ultrasound technique works by shooting high frequency waves of sound that are beyond the hearing threshold of human beings. These ultrasound waves cause enough disturbances in the water content of most tissues and therefore most ultrasound tests are prepared for by filling the bladder or the stomach. Ultrasounds are extremely useful in locating stones that form in the body. Gall stones are one such type. These can form in the body as a result of bile becoming too concentrated in the gall bladder and eventually causing a stone to crystallize and form. This is a painful condition, which is treated also with a form of ultrasound called shockwave lithotripsy. Kidney stones are also found and treated initially in a similar manner.
In lithotripsy, an ultrasound is used to aim a shockwave generator to the exact location of the stone. The patient is usually sedated as the procedure can be painful. The shockwaves then break up the stones that have formed just enough to cause them to be release out of the organ. Ultrasound results in uterine tests are also quite interesting. Here, the patient will have to drink a lot of water and fill the bladder for a proper view to be seen. One of the results of an ultrasound in the uterine region for a pregnant woman is to not see the fetus in the uterus. If pregnancy is confirmed but no fetus is seen this means that the fetus is growing outside the uterus - a condition called an ectopic pregnancy where the fetus has to be destroyed.
Ultrasound can also be combined with other techniques like an endoscopy. This method uses an endoscope and then an ultrasound to view inside hollow organs. Ultrasound can also be combined with a Doppler test as well and this can allow one to view the blood supply to a certain organ to check for occlusions and stenosis.
