Radiographic investigation plays a major role in Exploration of the genitourinary axis, which is principally carried out by ultrasound, genitography, CT and MRI. Ultrasound usually allows visualization of neonatal adrenal glands, which may be enlarged in infants with congenital adrenal hyperplasia. Ultrasound can also help in identification of müllerian structures. In a neonate, findings of ambiguous genitalia, enlarged adrenal glands, and evidence of a uterus are virtually pathognomonic for congenital adrenal hyperplasia. A genitogram can help in determination of ductal anatomy. Findings may indicate normal urethral anatomy, an enlarged utricle, a müllerian remnant in a male, a common urogenital sinus, or an area of vaginal and urethral confluence in female neonates. Although real time pelvic ultrasonography is less invasive than genitography, its yield in elucidating genital anatomy is comparable. The combination of both procedures is more informative and has a better yield. CT scanning and MRI can help in identifying internal anatomy.
