Filter by:Observational, single-center, prospective case-control study, in which each patient is his own control. It focuses on the study of tubal patency and establishing the agreement of results between HyFoSy and HSG.
Fallopian tube (FT) function is complex. One of the main functions is transport of sperms for fertilization and transport of the embry for implantation. Hysteroscopic access to "Darwish Hysteroscopic Triad" allows excellent way to assess FT patency. This study compares three ways of assessing FT patency separably or in combination: flow test, bubble flow test and peristalsis test. Combined bubble flow test and peristalsis test is recently published and coined (Darwishscope)1.
Tubal patency testing is essential for infertility evaluation. Standard tests are hysterosalpingography and laparoscopic perchromation test. In 2016, a hysteroscopic bubble suction test was described in apparently normal tubes. However, the efficacy of bubble suction test in abnormal tubes like hydrosalpnix has not been studied.
The purpose of this study is to summarize our experience with and to evaluate the feasibility of transvaginal four-dimensional hysterosalpingo-contrast sonography using SonoVue (4D-HyCoSy) for assessment of fallopian tubal patency, women attending the fertility clinic are recruited. All of the patients are tried to be examined with 4D-HyCoSy,some of who undergone laparoscopy and dye. Then the results of 4D-HyCoSy and lap and dye are compared. All of the patients will be followed up. The complications of 4D-HyCoSy will be evaluated and the pregnancy outcomes will be recorded.
The investigators' research group is working to develop a highly effective, low cost non-surgical method of permanent contraception for women. To support this goal, we need to know more about the normal fallopian tube (tube that passes the egg from the ovary into the womb). The purpose of this study is to learn about how menstrual cycles and hormonal contraceptives affect tubal patency. Normally there is an opening between the tube and uterus to permit the flow of fluid and cells. If this opening is blocked, this can result in infertility. Tubal patency is when a woman's fallopian tubes are not blocked. Tubal patency is determined by an x-ray test called a hystero-(uterus)salpingo-(fallopian tube)graphy (HSG). HSG is a standard radiological imaging study that is used to determine if the fallopian tubes are open and free of disease. It is commonly done in women with an infertility diagnosis. The investigators usually do this test in the first 10 days of the menstrual cycle. Sometimes the tubes will appear to be blocked on the HSG when they are actually open. The timing of the HSG study during the menstrual cycle, or the use of hormonal contraception may make a difference in whether the tubes appear blocked on the HSG when they are actually patent. The results of the HSG test provide a good model for how our nonsurgical permanent contraception method might work. The investigators think that if the tubes are not patent, that our treatment will not work as well. Therefore, in this study we want to learn if menstrual cycle timing or current hormonal contraception use will affect the patency of the tubes as assessed by the HSG. The investigators want to examine the same women to see if tubal patency is changes during the menstrual cycle and during the use of a birth control pill and the birth control shot.
A thorough infertility evaluation commonly involves determining whether a woman's fallopian tubes are patent. The two most often utilized methods of evaluating the fallopian tubes are hysterosalpingogram (taking an X-ray of the pelvis after injecting dye through the uterus and fallopian tubes) and laparoscopic chromopertubation (a surgical procedure in which dye is visualized passing through the fallopian tubes). The FemVue Saline-Air device is a new method of assessing tubal patency. The device utilizes a mixture of saline and air bubbles that can be seen passing through the fallopian tubes by ultrasound. FemVue can be efficiently performed in a physician's office and is minimally invasive. Unlike hysterosalpingogram and laparoscopic chromopertubation, it does not carry the risks of anesthesia or surgery, and doesn't expose the patient to radiation or contrast. It does, like the other two methods, carry a small risk of infection. This study will involve using the FemVue device on patients under anesthesia in the operating room before they undergo scheduled laparoscopic chromopertubation, the gold standard for evaluating tubal patency. The two methods will be compared to determine the accuracy of the FemVue device.
1. Methylene blue in laparoscopy use for tubal patency assessment 2. Methylene blue could have negative effect on sperm motility, oocyte granulosa cell and fertility. 3. tubal washing after Methylene blue administration could be effective in pregnancy rate after operation.
