Background: Oligohydramnios has been correlated with increased risk of fetal stillbirth, meconium aspiration syndrome, severe birth asphyxia, low Apgar score scores and congenital abnormalities. It is also associated with maternal morbidity due to increased rates of induction and instrumental or operative deliveries.

Aims & Objective: To assess maternal and perinatal outcome of sever oligohydramnios at term pregnancy and associated factors among pregnant women admitted from June 1, 2015 to June 30, 2017 at Gondar University Specialized Hospital, Northwest Ethiopia.

Methods and Materials: A descriptive cross-sectional study was conducted in Gonder University Specialized hospital from June 1, 2015 to June 30, 2017. The pregnant mothers admitted in the labor and delivery unit with a diagnosis of oligohydramnios at term singleton pregnancy with known gestation was included in the study. The data were collected using a structured and pretested questionnaire. It was entered in EPI Info7.0 and analyzed using SPSS 20.0. Logistic regression analysis was done to assess any factors associated with severe oligohydramnios.

Results: The calculated sample size was 334 and a total of 295 cases were analysed. Severe oligohydramnios was found in 93 (31.4%) of the cases. Idiopathic (unknown cause) was the most common obstetric complication of oligohydramnios identified in this study 259 (87.8%). Cesarean section was done for 237 (80.2%) of cases, the commonest indication being severe oligohydramnios(C/S can be decided for sole presence of sever oligohydramnios, for NRFHRP while on induction for oligohydramnios or for the presence of previous c/s scar or malpresentation that precludes induction of oligohydramniose cases in our set up). The likelihood of experiencing severe oligohydramnios was nearly three times higher among women with a history of hypertension (AOR= 3.22, 95% CI (1.24-8.36)) and previous history of abortion (AOR=3.42(1.26-9.23)). A unit increase in gestational age the odds of experiencing severe oligohydramnios almost doubled (AOR= 1.58, 95% CI (1.16-2.17)). Women who had ANC follow up at private clinics (AOR= 0.26, 95% CI (0.10-0.68)) were 74% lower odds of experiencing severe oligohydramnios.

Conclusion: There is significantly increased maternal morbidity in the form of a cesarean section (p<0.001) in pregnant women with term oligohydramnios. History of hypertension, previous history of abortion, place of antenatal follows up and increased gestational age were associated factors for the occurrence of severe oligohydramnios.
