Overview
Renal agenesis is diagnosed with routine screening with fetal ultrasound. Renal ultrasonography shows no renal parenchyma in unilateral renal agenesis (URA). Ultrasound findings in bilateral renal agenesis (BRA) may include: absence of fetal kidneys in the renal fossa, empty bladder and anhydramnios after 16 weeks of gestation. Absence of renal arteries on color doppler ultrasonography indicates bilateral renal agenesis (BRA) and may be used as an additive diagnostic tool.
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]
- Ultrasound findings in bilateral renal agenesis (BRA) may 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.[6]
