Premature rupture of membranes (PROM) constitutes one of the most important dilemmas in the obstetric practice. It could be defined as rupture of membranes before the onset of labor, irrespective of the gestational age (Ngwenya and Lindow; 2004).
Premature rupture of membranes occurs in 10% of all gestations and about 2-4% of preterm pregnancies. At term approximately 95% of women with PROM deliver within 28 hours after rupture. However, at earlier gestational ages, continuation of pregnancy is much more likely (Modena, Kaihura, Fieni, 2004).
The methods used to diagnose premature rupture of membranes are variable; it begins by history taking and clinical examination by vaginal speculum. Diagnosis may be helped by measuring Amniotic Fluid Index by ultrasound, by amnioinfusion of indigo carmine or other biological tests; vaginal Ph by nitrazine paper, prolactin, alpha fetoprotein, human chorionic gonadotropin and fetal fibronectin (Esim et al., 2003).
Recently, it is hypothesized that vaginal fluid urea and creatinine may be helpful in diagnosing PROM because fetal urine is the most important source of amniotic fluid in the second half of pregnancy (Kafali and Oksuzler, 2006).
