Pak J Med Health Sci Jan ;12(2):784-6.

Background: The number of deliveries through cesarean section has been increased in the last two decades. After cesareans section, uterine scar dehiscence is the most commonly occurring complication, especially in females undergoing trial of labor in previous cesarean section . Short Inter pregnancy interval (IPI) enhance the complication and raise the risk of uterine dehiscence or even rupture. Aims: To assess the frequency of short IPI in pregnant females with priorone cesarean section and to determine the association of uterine scar dehiscence in short IPI. Methods: This cross sectional study was conducted at Department of Gynecology, Services Hospital, Lahore, from October 2015 to March 2016. A total of 150 pregnant women with singleton pregnancy for >37weeks with only one previous low, transverse cesarean delivery were included. History was taken to determine the outcome variable ( short IPI ). Ultrasonography examination was performed on all patients to ascertain the presence of uterine scar dehiscence . All data was collected on predesigned proforma . Results: The mean age of patients was 31.946+-4.48 years. There were 42% females who had short IPI while 58% had normal IPI(>8months). Uterine scar dehiscence was seen in 5.3% patients. Uterine scar dehiscence was significantly association of short IPI with uterine scar dehiscence (relative risk =1.868 (95% CI; 1.194-2.923, P-values < 0 .0 5) Conclusion: A short IPI of <8 months may be a risk factor for uterine scar dehiscence . Although these findings are insignificant but need further trials to confirm the significance. The results suggested that obstetrician must take IPI in her knowledge before giving trial and during preconception counseling.
