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.
