An abdominal ultrasound usually includes three systems, such as the digestive system such as the liver, gallbladder, spleen, and pancreas, or the urinary system such as both kidneys, bladder, ureter, and prostate. In the case of women, it may be the gynecological system such as uterine adnexa. Depending on the disease, different departments are registered. If the problem is in the digestive tract and there is a suspected problem with the liver, gallbladder, spleen, or pancreas, you should register for gastroenterology or general surgery. If you suspect a urinary stone or urinary tract infection, accompanied by blood in urine or frequent, urgent, or painful urination, you should register with the Department of Urology. If a woman is suspected of having gynecological inflammation or gynecological tumor, it is recommended to consult the gynecology department.
