RENAL AGENESIS
Fig. 7.21 Unilateral renal agenesis, 26 + 0 weeks.
Color flow mapping shows only one renal artery.
Renal tissue and the renal artery are absent on the
contralateral side.
Fig. 7.22 Unilateral double kidney. One renal
artery is demonstrated on the right, but two arteries
branch off to the left.
death follows shortly after birth, due to hypoplasia
of the lungs.
Prognosis: Bilateral renal agenesis results in intrauterine
fetal death in 40%. The rest die usually
shortly after birth. Unilateral renal agenesis does
not affect the further development of the infant
and does not restrict the quality of life.
