ABSTRACT
Congenital anomalies of the female genital tract result from müllerian duct anomalies and/or abnormalities of the urogenital sinus or cloaca. Due to the close developmental relationship between the genital and the urinary tracts, association of anomalies in both systems are common. This article reviews the appearance of developmental anomalies of the female urinary and genital tracts and points out common associated malformations to allow an early and complete sonographic assessment of affected infant.

OBJECTIVE: The purpose of this article is to show the usefulness of sonography in diagnosing genital anomalies early in female neonates who have unilateral renal malformations. Our patients were three female neonates with renal anomalies that had been detected in utero. We performed sonography of the inner genitalia of each girl after filling the vagina with saline solution. In two patients with multicystic dysplastic kidney disorder, the examination revealed uterus didelphys with obstruction of one of the vaginas. Sonographic examination of the third patient showed Gartner's duct cyst with renal agenesis. CONCLUSION: The neonatal period provides a unique opportunity to use sonography to detect uterine anomalies because maternal and placental hormone stimulation increases the size of the uterus. Simultaneous intravaginal saline instillation during imaging further improves the radiologist's ability to diagnose genital malformations precisely. This procedure is a simple, sensitive, and inexpensive examination method that is useful in imaging female neonates with renal dysplasia or agenesis detected in utero or in the neonatal period. Its particular value is to further characterize a cystic mass posterior to the bladder that is seen at transabdominal sonography.

OBJECTIVE: The purpose of this report is to describe the relationship between the renal artery and the azygos vein in patients with congenital infrahepatic interruption of the inferior vena cava with azygos continuation. CONCLUSION: Using abdominal sonography, we showed that in patients with interruption of the inferior vena cava with azygos continuation, the renal artery is ventral to the azygos vein. Because this malformation is frequently associated with cardiac and situs anomalies, awareness of the anatomic relationship between the renal artery and the azygos vein can aid in diagnosis and may substitute for more expensive and invasive diagnostic procedures.
