“…The study by Guin G et al [7] observed fetal congenital anomalies in 4.2%, which is comparable to our study. In a study conducted by Levine D et al [8] , the most common congenital anomalies observed were hydronephrosis, ventriculomegaly, intestinal atresias, congenital diaphragmatic hernia, hydrops, skeletal dysplasias, cloacal malformations and gastoschisis. In the study conducted by C Stoll et al [9] the more frequent malformations associated with oligohydramnios were urinary, musculoskeletal, digestive and cardiac.…”

Background: The amniotic fluid is a cocoon of protection in fetal life. Amniotic fluid volume is an indicator of fetal wellbeing. Too little amniotic fluid is called oligohydramnios and is associated with increased incidence of congenital malformations and neonatal mortality. Aims & Objective: To estimate the incidence of congenital malformations and to study the perinatal outcome in oligohydramnios. Material and Methods: This prospective study was conducted in the Neonatal intensive care unit and the maternity wards of Father Muller Medical College Hospital, Mangalore. Ultrasound assessment of amniotic fluid index was recorded and cases of oligohydramnios detected were followed up. Congenital malformations were observed both by ante natal and post natal ultrasounds, other relevant investigations were also done when necessary. The perinatal outcome in terms of fetal distress, mortality and intrauterine growth retardation were recorded. Results: 120 cases of oligohdramnios were recorded. Seven newborns with congenital malformations were detected (5.8%). The most common congenital malformation was hydronephrosis. Four neonatal deaths were recorded in the study (3.3%). Fetal distress was observed in nine neonates (7.5%) and thirty neonates (25%) had intrauterine growth retardation. Conclusion: Congenital malformations, neonatal mortality, fetal distress and intra uterine growth retardation are significant risks in oligohydramnios. The lower the amniotic fluid index more is the risk of both mortality and congenital anomalies.

“…Sonography is an excellent means of evaluating the fetal genitourinary tract [1][2][3][4][5][6]. However, some factors, including the patient's body habitus and oligohydramnios, can often prevent optimal assessment of anomalies of the genitourinary system using sonography.…”

MRI was performed on 35 pregnant women with sonographic findings that suggested that their fetuses had genitourinary anomalies. Oligohydramnios or anhydramnios was identified in 22 of 35 women and did not hinder visualization of anomalies. MRI allowed the amniotic fluid and the presence, location, and morphology of kidneys and bladder to be assessed in all fetuses at any stage of gestation and depicted sufficient anatomic detail for us to evaluate the perineum in 27 of 35 pregnancies. Therefore, we found MRI to be an excellent technique for revealing the anatomy of genitourinary anomalies in the fetus.

“…However, although oligohydramnios subjectively degrades image resolution, Levine et al [20]showed that sonography still reveals important fetal anatomic landmarks. Major anomalies can be detected on sonography even when the pregnancy has less than the normal volume of amniotic fluid [20]. …”

Objectives: To provide data on oligohydramnios associated with congenital anomalies in 225,669 consecutive pregnancies. Material and Methods: The malformations in this study came from births of known outcome recorded in our registry of congenital malformations. Routine ultrasonographic examination was performed. Diagnosis of oligohydramnios was made ultrasonographically. For each case, a control was chosen. Results: The prevalence of this association was 0.99 per thousand (224 cases). A case-control study allowed the examination of genetic and environmental factors for the origin of oligohydramnios associated with congenital malformations. Diagnosis of oligohydramnios associated with congenital malformations was made prenatally in 32.6% of the cases; 12.0% of the infants were stillborn. Fifty-nine percent of the cases had more than one malformation, 13.8% had a chromosomal aberration, and 27.6% had multiple malformations that do not constitute a syndrome. The more frequent malformations associated with oligohydramnios were urinary, musculoskeletal, digestive and cardiac. There was increased parental consanguinity. The frequency of oligohydramnios and congenital anomalies among first-degree relatives was 4.5% and first-degree relatives had more malformations than controls (8.0 vs. 3.1%, p < 0.05). Threatened abortions and diabetes mellitus were significantly more frequent among mothers of the children with congenital malformations associated with oligohydramnios than among the controls. Conclusions: Our study demonstrated that careful fetal examination has to be performed when oligohydramnios is diagnosed as congenital malformations are often associated with oligohydramnios. We recommend the use of fetal chromosome analysis and careful ultrasonographic examination in every pregnancy complicated by oligohydramnios.
