Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
There are many causes for induction of abortion in the second trimester such as missed abortion, serious fetal abnormalities such as central nervous system or skeletal malformation and lastly some women do not wish to continue a pregnancy and will often seek out termination of pregnancy.
Termination of second trimester is more risky than the first trimester. So many lines have been emerged to achieve safe and effective method of termination of second trimester.
Pharmacologic management seems to be an appealing method for induction of abortion. The combing between mifepristone and misoprostol is the effective regimen for termination of second trimester abortion with success rate reaching about 97-99% within 24 hours.
However, mifepristone is not available or affordable in many countries worldwide so misoprostol have been used alone but it needs higher total dose with lower effectiveness and higher percentage of side effects rate than the combined regimens.
The optimal method for inducing second trimester nulliparous women with an unfavorable cervix is not known. Several studies in literature have described the effectiveness of Foley's catheter in cervical ripening and improvement of Bishop's score in women with unripe cervices . It may act in addition to its mechanical effect by increasing the release of prostaglandin and/or oxytocin release secondary to localized inflammation.
In practice, the insertion of intra-cervical Foley's catheter balloon is followed by applying tension in trial to shorten the time between the insertion and expulsion of the fetus, however; this tension adds more pain for the pregnant women with higher rate of vaginal bleeding and dissatisfaction.
Gary et al in 2016 concluded that the application of tension did not result in faster delivery times, but did result in faster times to catheter expulsion.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Foley Catheter Balloon with Tension group
a 16 French transcervical Foley catheter balloon will be advanced to or past the internal os and the balloon will be filled. Then catheter will be placed on gentle traction by taping the distal tip to the medial thigh for maximum 24 hours. To maintain gentle traction, periodic repositioning of the distal tip on the thigh will be necessary.
Tension group
Foley catheter Balloon
Foley Catheter Balloon without tension group
The Foley catheter balloon will be just supported by simple taping to the thigh.
No tension group
