What are the advantages of tubal recanalization intervention?

1. It requires no surgery, no general anesthesia, is painless, safe, and effective.

2. It causes minimal damage, results in quick recovery, and has good outcomes, with minimal interference to the body, largely protecting and preserving normal tissues and organs.

3. Outstanding therapeutic effects: For interstitial and isthmic tubal obstructions, this treatment directly replaces traditional surgical methods and can preserve normal tissues.

4. While there is no cure for cancer, interventional therapy can localize drugs to the site of the lesion as much as possible, thereby reducing side effects on the body and other organs.

1. The procedure is performed 3-7 days after the menstrual period, with no infection in the genitalia or pelvic cavity.

2. Bilateral or unilateral interstitial, isthmic, and proximal ampullary tubal obstructions, requiring tubal recanalization.

3. Routine hysterosalpingography cannot be completed due to excessive cervical dilation; this examination can be performed.

4. Bilateral or unilateral tubal obstruction with poor patency, excessive thinness, or torsion, primarily treated with catheter dilation followed by catheter insertion for drug administration to reach the lesion site and reduce the degree of obstruction.

5. Tubal pregnancy, where a catheter is inserted into the affected tube, and medication is injected to inactivate the embryo, terminate the pregnancy, and treat ectopic pregnancy.
