Patient's question:
I was once your patient.Doctor's answer:
Tubal blockage is a common cause of infertility, accounting for one-third of infertile patients, and has shown a gradual increasing trend in recent years, making it a challenging issue in the treatment of infertility. Tubal blockage is primarily caused by inflammation spreading from the endometrium upwards, first leading to inflammatory changes in the tubal mucosa. The tubal epithelium undergoes degenerative changes or falls off in patches, resulting in adhesion of the tubal mucosa, followed by occlusion of the tubal lumen or fimbriae. Traditional treatment methods mainly include tubal irrigation or surgical intervention. Tubal irrigation, although simple to perform, has poor accuracy and unsatisfactory outcomes, and has gradually been phased out. Tubal implantation, anastomosis, or fistuloplasty, among other surgical microsurgical procedures, require high technical expertise, are costly, and have uncertain efficacy in functional recovery.
