Abstract
Background: Preterm premature rupture of membranes (PPROM) occurs in 17% of pregnancies, which leads to 20% of perinatal death. According to previous studies uterine anomalies are one of the risk factors for preterm birth, PPROM and pregnancies complications. The aim of this study was to evaluate the relationship between PPROM and rupture of membrane (ROM) with uterine cavity anomalies based on hysteroscopic findings.
Methods: This cross-sectional study was conducted in Imam Khomeini Hospital, Ahvaz, Iran, from May 2011 to May 2012. After conducting a pilot study, 66 nulliparous pregnant women at 14-37 weeks of pregnancy with PPROM and ROM were selected randomly. Then the women were evaluated by hysteroscopy at least six weeks after delivery or miscarriage. The control group includes 66 women with at least one normal pregnancy (without history of PPROM, secondary infertility or recurrent abortion), who underwent diagnostic or therapeutic hysteroscopy for other reasons than PPROM. The hysteroscope instrument specifications were KARL STORZ model (KARL STORZ GmbH & Co. KG, Tuttlingen, Germany), inner sheet 26153 BI, outer sheet 26153 BO, and BA lens with 30 degree. Normal saline solution (Sodium Chloride 0.9%) also was applied as distention medium. The study was approved by Ethic Committee of Ahvaz Jundihspur University of Medical Sciences. Informed consent was obtained for all participants.
Results: Overall, the frequency of uterine anomalies in case and control groups was 12.12% and 3%, respectively (P<0.05 based on Chi-square test). Possibility of uterine cavity anomalies in the women with preterm premature rupture of membranes (PPROM) was significantly higher than the women with normal pregnancy (OR=4.41, CI 95%: 0.9-21/63). About 3% of patients in the case group had undefined uterine anomalies. This anomaly was not in mentioned uterine anomalies classification of American fertility association. We did not observe such anomaly in control group.
Conclusion: In conclusion, we found that the possibility of occurring PPROM in women with uterine cavity anomaly was four-fold more than women without these anomalies. Hence, we recommend women with history of PPROM to undergo diagnostic hysteroscopy for detecting uterine anomalies before next pregnancy.

Abstract
Background: Preterm premature rupture of membranes (PPROM) significantly impacts perinatal mortality and maternal-fetal outcomes. The purpose of this study is to investigate the frequency of maternal risk factors, maternal and fetal outcomes and the role of care in the occurrence of outcomes.
Methods: This retrospective cross-sectional study involved 317 pregnant women with premature rupture of membranes (PPROM) at Shahid Beheshti Hospital in Isfahan, between April 2020 and April 2022. Data were collected from medical records, including demographic information, risk factors, and maternal and neonatal outcomes. Patients were categorized into two groups: those receiving care (24-34 weeks of gestation) and those undergoing pregnancy termination (less than 24 weeks or more than 34 weeks). The chi-square test was used for qualitative variables, while the T-student test was applied for quantitative variables.

Results: In this study, the average age of patients was 29.42±6.56 years. The most common risk factors for PPROM were 20.2% for abortion records, 20.2% for urinary infections, 18% for cervical insufficiency, and 13.6% for gestational diabetes. Comparing maternal outcomes between the two groups revealed that chorioamnionitis occurred more frequently in the care group (18% vs. 2%, P=0.0001), as did emergency cesarean sections (37% vs. 4.5%, P=0.0001) and NICU hospitalization (71% vs. 17%, P=0.001). In the next stage, a regression test identified the independent effects of variables on maternal and newborn outcomes without intervention or confounding factors. The analysis indicated that mothers in the care group experienced significantly more complications than those in the pregnancy termination group, and their babies also faced significantly more complications.
Conclusion: The study results indicate that a history of abortion, urinary infections, cervical insufficiency, and gestational diabetes are significant risk factors for PPROM. Expectant management of PPROM is associated with more neonatal and maternal complications than pregnancy termination. Thus, timely identification of these risk factors allows healthcare providers to educate mothers and potentially prevent and manage them, significantly reducing the incidence of PPROM and its complications.
