Laparoscopy & ultrasound pictures & discussion of hydrosalpinx

Blocked and dilated fallopian tubes in infertile women

A hydrosalpinx is a blocked fallopian tube that is filled with fluid. It can be dilated to varying degrees from the accumulated fluid. Doctors can diagnose a hydrosalpinx in several ways including ultrasound, surgery such as laparoscopy, or with a specialized x-ray test called a hysterosalpingogram, or HSG.

Tubal blockage and tubal infertility is usually a result of previous pelvic infection such as pelvic inflammatory disease, but also can be caused by endometriosis and other conditions. Because fertility specialists are lazy, they often use the nickname "hydro".

Women with bilateral (both sides) tubal damage and hydrosalpinx are infertile and will need either tubal surgery, such as neosalpingostomy, or in vitro fertilization in order to get pregnant.

Hydrosalpinx and IVF success rates

If a woman going through IVF has a hydrosalpinx visible by ultrasound, the average expected IVF success rate is lower compared that expected in a similar patient without a hydrosalpinx. If there is are bilateral hydrosalpinges (hydros on each side - plural of hydrosalpinx is hydrosalpinges) visible on ultrasound, studies have shown that the expected IVF success rate is lower than with a hydro on one side.

The medical studies on hydrosalpinx and IVF outcome agree that there is a decrease in success rates, but they do not agree on the amount of the decrease caused by the hydro. In general, studies suggest that the chances for live birth are reduced about 25% with a hydro present on ultrasound.

IVF success rates vary significantly between different centers - it is wise to research IVF live birth rates carefully before choosing a clinic for the treatment.

Careful ultrasound examination should be able to detect any significant hydrosalpinx. Studies have shown that if surgery is performed to remove the fallopian tube (or tubes), the expected IVF success rate is normalized.
