Fusion of the upper or lower poles of the kidneys produces a horseshoe-shaped structure continuous across the midline, anterior to the great vessels. This anomaly is relatively common and is found in about 1 in 500 to 1 in 1,000 autopsies.1 Although the majority of such kidneys are fused at the lower pole, 10% are fused at the upper pole.1 This developmental abnormality occurs between approximately 7 and 9 weeks of gestation.2 We present a case of the prenatal sonographic findings associated… 
Horse-shoe Shaped Kidney in Fetus and its Associated Variations: A Case Report
Horseshoe kidneys are found in 3% of the population and are probably the most common of all renal fusion anomalies, and may increase the risk for ureteric obstruction, venacaval obstruction, renal infections associated with vesicoureteral reflux, renal stones and increased risk of renal cancer.
Sonographic Findings of Fetuses with an Empty Renal Fossa and Normal Amniotic Fluid Volume
The underlying cause of ERF in the majority of cases with normal amniotic fluid volume is renal ectopia, and prenatal ultrasonography seems to be highly reliable in diagnosing these anomalies.

The aim of this study was to evaluate the usefulness of measurement of the angle between bilateral renal pelves on axial views in the prenatal ultrasonographic diagnosis of horseshoe kidney.

Sonography of fetal urinary tract anomalies.
Experience with 13 cases and a review of 41 cases in English literature indicate that anomalous development of the fetal urinary system can be detected in utero using sonography. Anomalies not

Careful second- and third-trimester ultrasound examinations can detect an absence of the kidney in the renal fossa, and evaluating the migratory path of the kidneys from the pelvis to the renal Fossa will frequently result in detection of an ectopic kidney.
Ultrasound diagnosis and perinatal management of fetal genito-urinary abnormalities.
If there is massive enlargement of the fetal abdomen, elective cesarean delivery should be considered to prevent the dystocia which may occur with vaginal delivery and to prevent further damage of these vital organs.
Prenatal diagnosis of pelvic kidney
A 30‐year‐old woman had serial ultrasound scans from 28 weeks' gestation which revealed the presence of a cystic area in the fetal pelvis which remained unchanged until delivery at 41 weeks, when a pelvic kidney was confirmed at birth.
Routine fetal genitourinary tract screening.
To evaluate routine fetal genitourinary tract obstetrical ultrasound screening, and to determine what size renal pelvis is indicative of significant renal disease, we reviewed 4,832 examinations,
Antenatal diagnosis of renal abnormalities: a review of the state of the art.
The indications and techniques of antenatal diagnosis of renal and urinary tract abnormalities are reviewed, and their follow-up and modes of treatment are outlined.
