Depending on the level of the hospital, the location of the hospital, and the instrumentation, the price of the ultrasound varies. Generally, the vaginal ultrasound examination in a tertiary hospital is about 200 yuan. Because vaginal ultrasound does not need to hold urine, it can avoid the interference of intestinal gas and make the image clearer, and can diagnose endometrial polyps, endometrial tumors, cervical cancer, cervical cysts, adenomyosis, endometriosis, ovarian cysts, ovarian tumors, inflammatory masses in the ovaries, tubal effusions, pelvic effusions, and uterine congenital developmental malformations and other diseases.
