Objective: To assess the role of ultrasonographic measurement of the upper and lower uterine segments wall thickness in predicting the progress of preterm labour in patients presenting with preterm labour pains. Study design: Fifty pregnant women presenting at Obstetrics Department -Suez Canal University, Egypt with regular lower abdominal pains and diagnosed as having preterm labour were enrolled in the study. Materials and Methods: Measurements of the upper and lower uterine segments wall thickness by transabdominal ultrasonography in-between contractions and with full bladder were taken. The upper/lower uterine wall thickness ratio was calculated and correlated to the progress of the preterm labour and to the response to tocolytics. Results: The ultrasonographic upper/lower uterine wall thickness ratio was directly related to the progress of preterm delivery (PTD). The change in this ratio is correlated inversely with the response to tocolysis. Using the ROC curve, when the upper/lower uterine wall thickness ratio was ≤ 1.26 the sensitivity was 94.74 and the specificity was 100.00, and when the ratio was ≤ 1.52 the sensitivity was 100.00 and the specificity was 83.33. Conclusions: These data may serve as a baseline ultrasonographic reference values for further studies in prediction the progress of preterm labour in patients presenting with preterm labour pains.

The aim of this study was to evaluate the efficacy of magnetic resonance (MR) in the assessment of pregnant women with acute abdominal and pelvic pain. Patients and methods: A prospective study was conducted from April 2011 to March 2013 in Security Forces Hospital, Riyadh, Kingdom of Saudi Arabia (K.S.A). MRI study of 25 patients presented with acute abdominal and/or pelvic pain in which ultrasound was indeterminate, were included in this study. Multiplanar magnetic resonance images of the pelvis were obtained and independently reviewed by two radiologists with discrepancies was resolved by consensus. Data from both magnetic resonance imaging and ultrasonography were obtained, and the definite diagnosis was established with laparoscopic or open surgical findings and results of clinical follow-up as the reference standard. Results: Correlation of prospective clinical MR interpretations with follow-up medical records showed correct identification of disease entities in all patients. The following disease processes were identified using MRI: appendicitis (n = 3), pyelonephritis (n = 3), hydronephrosis (n = 2), pancreatitis (n = 2), uterine fibroid degeneration (n = 4), degeneration and torsion of a subserosal uterine fibroid (n = 2), simple ovarian cysts (n = 3), and ovarian torsion (n = 2), ulcerative colitis (n = 1), Crohn's disease with perianal fistula (n = 1), and pelvic congestion syndrome (n = 1). Two of the 25 patients had normal findings on MR examinations and unremarkable follow-up. Conclusion: Magnetic resonance imaging (MRI) is an accurate, useful and safe in detecting the cause of acute abdominal/pelvic pain in pregnant patients.
