Fetal compensatory renal hypertrophy with a unilateral functioning kidney
1Department of Obstetrics, Gynecology and Reproductive Sciences, Magee-Womens Hospital, Pittsburgh, Pennsylvania.
Abstract
Objective:
To evaluate the possibility of fetal compensatory renal hypertrophy with a unilateral functioning kidney.
Methods:
A nomogram of renal length was established from 254 normal fetuses. Renal length was also obtained in 14 fetuses with unilateral renal agenesis and 22 fetuses with a unilateral multicystic kidney.
Results:
Compensatory renal hypertrophy, defined as a renal length > 95th percentile for gestational age, occurred in 16 of 36 cases (44.4%).
Conclusions:
Compensatory renal hypertrophy is detectable in utero and may occur as early as 22 weeks' gestation.
