We aimed to determined; affect of clinical, laboratory, and ultrasonographic factors the time elapsed until the birth in midtrimester PPROM and PTE. Total 448 PPROM and PTE patients were conceived which applicant the Perinatology Department of zekai Tahir Burak Women's Health Education And Research Hospital between 2012-2014 years. PPROM group consisted of 237 patients, PTE group consisted of 211 patients. PPROM and PTE groups were divided into subgroups as cervical culture positive and negative PPROM and PTE groups. Risk factors of until the time of birth was determined by multivariate regression analysis in cervical culture positive PPROM and PTE groups. Cervical length measured by TVUSG=0,907, 95% Cl = 0,823-0,999 (p=0,047) and amniotic fluid index (or= 0,962, 95% Cl= 0,946-0,980 (p
