The Turkey from Asia (47.9% and 47.5%, respectively), number of babies delivered by CS is rapidly growing Italy (38.1%) from Europe, United States (32.8%) from both in developed and the developing countries. The Northern America, and New Zealand (33.4%) from rate of CS ranged from 12% - 86% in the industrialized Oceania[4]. CS is a common obstetric procedure[5] and countries[3]. In the developing nations, CS rates ranged the reasons behind its continuous increasing rates between 2 - 39%[3]. The countries with the highest appeared to be multiple, complex and, may be in many CS rates as reported in 2016 were Brazil (55.6%) and cases, specific to the country[1,2].

A retrospective record review study There are many concerns regarding the escalating (16-years’ trend of CS): All records of deliveries done rise in CS rates due to potential maternal and perinatal in the Obstetrics & Gynaecology Department of the risks, the probability of obstetric complications University Hospital during a 16 year period (2000 - in upcoming pregnancies and financial issues[9]. 2015) were reviewed. The increased rates of CS lead to increased scar Data was collected through a pre-constructed pregnancies, which can have lethal consequences clinical data abstraction sheet. It was used to collect and may affect infant immune system[2]. Females information about the numbers and methods of previously delivered by CS may be more liable to deliveries (CS or VD). The types of CS such as upper postpartum haemorrhage and retained placenta. segment, transverse and lower segment CS (LSCS) Uterine rupture and placenta previa are well-known were also recorded. Similarly, the types of VD such as and potentially life-threatening complications spontaneous VD (SVD), breach and assisted deliveries of previous CS, but are fortunately still rare (ventouse and forceps) were also noted. conditions[10]. 2. A matched case-control study: Eligibility The World Health Organization has stated that criteria for enrolment in this part of the study included maximum CS percentage should be 15%, and that all females in the reproductive age, who attended no region in the world is justified with having a the Gynaecology and Obstetrics Department of the caesarean rate greater than 10% to 15%[9].
