Hysterosalpingo-Foam Ultrasonography Combined With Power Doppler, Compared With Laparoscopy in Tubal Patency Assessment in Cases of Infertility

"* Initial 3-5 ml of foam contrast is to be introduced slowly into the endometrial cavity while the flow of contrast medium in each tube is evaluated using grayscale and power Doppler imaging~* Power Doppler is very helpful to confirm the direction of the flow as well as the acceleration during injection"

• Standard laparoscopic evaluation with the dye test (methylene blue staining) is to be performed 1 day after ultrasound tests with 1 day of hospitalization under general anesthesia
