Background: Preterm birth (PTB) is one of the most important unsolved problems in reproductive medicine. Thisstudy aims to evaluate several maternal risk factors and outcome of pregnancies who were admitted for pretermspontaneous uterine contractions (PSUC).Methods: From September 2007 to February 2009, 327 cases who were admitted for PSUC were retrospectivelystudied. They were classified according to their fetal numbers and presence of true versus threatenedpreterm labor (PTL).Results: There were 297 (90.82%) singleton, 27 (8.25%) twin and 3 (0.91%) triplet pregnancies. Only 12 women(3.6%) fulfilled the ACOG criteria for PTL who delivered in a few hours and 315 cases (96.3%) were classified asthreatened PTL and most of them were discharged undelivered from the hospital. 103 cases were missed and 224mothers and their 247 neonates remained. 121 women from this cohort had PTB and delivered before 259 days(54%). Pregnancy outcomes including; the time interval between admission for PSUC and delivery, the mean gestationalages at birth, birth weights, number and duration of NICU admissions were evaluated in each group.Conclusion: Regular uterine contractions even in the absence of cervical changes should be considered as apotential risk factor for PTB. The most frequently associated maternal risk factors were history of abortion, infertilityand previous PTB, and the most frequently associated complications were preterm rupture of membranes,vaginal bleeding and febrile diseases.
