“…In the skeletal system, severe dysplasias and spinal anomalies were identified (98)(99)(100)(101). Sonographic characteristics of a variety of abnormalities of the genitourinary tract were reported (101,102), and researchers developed criteria to distinguish normal fluid in the renal collecting system from hydronephrosis. Gastrointestinal obstructive abnormalities and other anomalies were described (101)(102)(103)(104)(105), as were anomalies of the neck, such as cystic hygromas (106), and the thorax, including diaphragmatic hernias (107) and pulmonary masses.…”

A sophisticated body of knowledge has developed around the sonographic evaluation of fetal cardiac structures and function, to the point that a special term fetal echocardiography is commonly used to describe US of the fetal heart (108).…”

During the past century, imaging of the pregnant patient has been performed with radiography, scintigraphy, computed tomography, magnetic resonance imaging, and ultrasonography (US). US imaging has emerged as the primary imaging modality, because it provides real-time images at relatively low cost without the use of ionizing radiation. This review begins with a discussion of the history and current status of imaging modalities other than US for the pregnant patient. The discussion then turns to an in-depth description of how US technology advanced to become such a valuable diagnostic tool in the obstetric patient. Finally, the broad range of diagnostic uses of US in these patients is presented, including its uses for distinguishing an intrauterine pregnancy from a failed or ectopic pregnancy in the first trimester; assigning gestational age and assessing fetal weight; evaluating the fetus for anomalies and aneuploidy; examining the uterus, cervix, placenta, and amniotic fluid; and guiding obstetric interventional procedures.

“…Until now eleven papers [1,5,8,10,11,12,14,15,19,20,21] reported a total of 36 cases of fetal hydronephrosis presumably not due to low urinary tract obstruction with controlled neonatal outcomes. Therapeutic abortions were performed in two cases, postnatal surgery in twenty, severe associated malformations occurred in five cases and neonatal mortality was 14% mostly due to malformations other than hydronephrosis.…”

This report covers 30 cases of prenatal diagnosis of uni- or bilateral hydronephrosis not associated with an overdistended bladder. Oligohydramnios was observed only in four cases while polyhydramnios occurred in three affected fetuses. In no case was fetal urine aspirated or drained prenatally. Early delivery was performed in four cases with oligohydramnios. Sixteen newborns required surgical correction of the lesion as it was confirmed by urography, following at least two sonographic examinations which confirmed a moderate to severe hydronephrosis after birth. The most frequent lesion was pyelo-ureteric junction obstruction (12 cases). Thirteen cases were normal at follow-up, and in two of these the dilation cleared up during intrauterine life. One case of severe hydronephrosis proved to be a multicystic kidney. In this series isolated hydronephrosis, both uni- or bilateral did not result in fetuses being at high risk for survival (only one infant died after surgery) nor as regards to associated malformations and perinatal morbidity. Provided a properly timed surgical correction was performed, renal function resulted to be good at follow-up.

Prenatal evaluation of partial obstruction of the urinary tract.

Abstract: Hydronephrosis was discovered in a fetus at the end of the second trimester. Serial sonographic studies over an eight-week period clearly showed the obstruction to be incomplete. This was confirmed in the early neonatal period.
