If a woman’s ultrasound examination reveals a cyst at the back of the uterus, she will have to choose the best treatment plan according to the size of the cyst, as well as the source of the cyst and accompanying symptoms. If the cyst is found to be on the ovary and there is no discomfort, and the cyst is less than 3cm, then no special treatment is needed, and the ultrasound will be repeated in half a year. If the examination finds that the cyst is in the woman’s fallopian tube and is accompanied by persistent pain in the lower abdomen, and the blood routine also suggests that there is an obvious infection, then the cyst is often considered to be due to pelvic inflammation, and then it is necessary to carry out anti-inflammatory treatment to relieve pain, and it is usually necessary to enter the antibiotics into the vein, such as ornidazole injection, parvufloxacin, and so on. If the cyst is found to have abnormal disorganized echoes and is more than 5cm, then it is best to consider laparoscopic exploration for treatment.
