Patient's question:
I haven't been using contraception for seven and a half months, but I haven't gotten pregnant yet. All the gynecological examination results are normal, and my menstrual cycle is regular. I want to have a fallopian tube examination. What should I pay attention to?Doctor's answer:
Uterine tubal proximal obstruction accounts for 10% to 25% of female tubal diseases. The recanalization of proximal tubal obstruction can be achieved through hysteroscopic COOK catheter recanalization or partial tubal resection and anastomosis. Hysteroscopic catheter recanalization involves inserting a COOK catheter into the interstitial part of the fallopian tube under hysteroscopy for tubal irrigation. The recanalization of the interstitial and isthmus parts of the fallopian tube is achieved through the separation and dilation effect of the catheter and the impact of the liquid. The surgical procedure is simple but relatively expensive. Approximately 85% of proximal tubal obstructions can be resolved through proximal catheter dilation. However, postoperative pregnancy rates vary widely, ranging from 12% to 39%, with an ectopic pregnancy rate of 2% to 9%. For patients who cannot undergo catheter recanalization, tubal partial resection and anastomosis can be considered to locate the obstruction.
