Overview
Ultrasound
Ultrasound
- Renal agenesis is diagnosed with routine screening with fetal ultrasound.[1]
- On prenatal ultrasound, normal kidneys may be visible at 9 weeks of gestation.[2]
- Renal ultrasonography shows no renal parenchyma in unilateral renal agenesis (URA).[3]
- Indicators of bilateral renal agenesis (BRA) on ultrasound include:[4]
- Postnatal renal ultrasound may be helpful in differentiating unilateral renal agenesis (URA) from multicystic dysplastic kidney (MCDK), renal aplasia or renal ectopia.[5]
Color Doppler Ultrasound
- Absence of renal arteries on color doppler ultrasonography indicates bilateral renal agenesis (BRA) and may be used as an additive diagnostic tool. (11 in huber)
