The recanalization treatment of obstructed fallopian tubes with the modified coaxial microtube

Objective The research is to rescue the blocked fallopian tubes to be patents again and to improve the efficacy of treatment. Methods We placed microtube into the entrance of fallopian tube to separate the adhesion with high pressure. For severe cases we used guided wire for recanalization. After alternative pushing and injecting for several times, most of the obstructed fallopian tubes could be recanalized. Results 365 blocked fallopian tubes of 200 patients resumed patency in 394 branches. Among them, 82 patients got succesful pregnancy. Conclusion The modified coaxial microtube proceduce can make most patients with blocked fallopian tubes to be recanalized, especially those with othstruction at the fimbriarted ends.
