The cost of laparoscopic unblocking of the fallopian tubes is about 10,000-15,000 RMB. Before the operation, routine checkups should be performed, including ultrasound to understand the condition of the uterine adnexa and the thickness of the endometrium, routine blood tests, routine leucorrhea tests, and tests for infectious diseases. If there is no abnormality in the examination, the patient will undergo routine surgery 3-7 days after menstruation and laparoscopic exploration will be performed to see if the fallopian tubes are tortuous, edematous or the umbilical ends of the tubes are closed. Laparoscopic repair and reconstruction of the umbilical end of the fallopian tube and combined hysteropelvic lavage can be performed, usually under direct vision, and pregnancy is required within three to six months after tubal lavage.
