Background: Any time before labor that termination of pregnancy for mother and fe-tus is better than keeping pregnancy, this is indication of induction for labor. The condi-tion of cervix is the most important factor for labor induction. Cervical condition, In many cases that candidate for induction of labor before labor pain, is poor. As the cervical ripening is quite important for success of labor induction. This study is attempting to compare two methods of cervical ripening. Methods: During this clinical study, 100 patients admitted in Ahwaz Imam Khomeini Hospital from 2010 to 2011. All of these patients had BISHOP score bellow 5, were di-vided to two groups for cervical ripening. Group one: trans cervical catheter and group two: laminaria. After placing transcervical foley catheter and laminaria for patient in-duction with oxytocin was started according to classic protocol. Then the time lapse from the beginning of induction to enter the active phase of labor and also from start of induction till delivery and appearing the side effect in both group was assessed. The result was analysed by SPSS 16 program. Results: Fifty three of patient (53%) were primiparous and the rest 47 (47%) were mul-tiparous. All of them had bishop score bellow 5. The average age for the patient group 1 was 27.1 and the average age for other group was 27.18. The time lapse from start of induction to enter active phase of labor in first group was 5.7±2.67 hours and this time for 2nd group was 7.51±2.33 hours. Also the time interval between the start of induction and delivery in group 1 was 10.3±4.35 hours and this time for group 2 was 12.5±4.9 hours. In both cases there was meaningful difference between two groups. There was no difference between both group for appearing the side effects. Conclusion: Based on this study, it seems using trans- cervical catheter for cervical rip-ening and aid to successful induction of labor is beneficial.
