Coil Hysteroscopic Tubal Occlusion in the Treatment of Hydrosalpinx

Coil Hysteroscopic Tubal Occlusion : the Treatment of Hydrosalpinx Before IVF-ET

this study is to investigate the success rate of proximal tubal occlusion with coil devices in women with hydrosalinx and to observe there pregnancy rate with IVF-ET.

In this study, investigators will recruit 80 females with unilateral or bilateral hydrosalpinx as confirmed by HSG. Tubal ligation may be a safe and effective method in the treatment of hydrosalpinx. But in this study, investigators will use fiber platinum coils to occlude the tubes. After the treatment, IVF-ET will be applied,and then the patients' pregnancy rate will be assessed in the following-up.

Inclusion Criteria:

1. Have unilateral or bilateral hydrosalpinxs as evidenced by HSG.
2. laparoscopic surgery was considered to be contraindicated because of ex-tensive pelvic adhesions.
3. Are willing to undergo a hysterosalpingogram (HSG) 1 months after fiber platinum coil placement to confirm proximal tubal occlusion.
4. Are willing to participate in this clinical study .Are able to comprehend and give informed consent for participation in this study.
5. Have read, understood and signed an informed consent form .

Exclusion Criteria:

1. Active or recent upper or lower pelvic infection
2. Known hypersensitivity to nickel as confirmed by skin test
3. Known allergy to contrast media Pregnancy or suspected pregnancy
