The water used for tubal irrigation is usually saline and most of it will flow into the abdominal cavity, but if the fallopian tubes are completely blocked, the injected fluid will flow out through the vagina. During the procedure, if the tubes are completely or partially open, most of the injected fluid will flow into the abdominal cavity, where it will be absorbed by the peritoneum and enter the blood circulation. However, if the tubes are completely blocked, the injected fluid will not be able to pass through the tubes into the abdominal cavity, but will flow back through the uterine cavity and out again through the vagina. After the operation of tubal irrigation, vaginal operation and sexual life should be prohibited for two weeks after the operation, and also prohibit the pelvic bath, so as to prevent bacteria from entering the abdominal cavity along the pathway of the tubal irrigation operation and causing infection in the abdominal cavity.
