Abstract

OBJECTIVE: Our purpose was to establish a reference range of fetal serum beta(2)-microglobulin, an index of glomerular filtration rate, andto compare the values obtained in fetuses with urinary tract anomalies with this range. STUDY DESIGN: Serum beta(2)-microglobulin was measured in 53 control fetuses at 18 to 39 weeks' gestation and in 14 fetuses with urinary tract anomalies, 9 of which had simultaneous urine sampling. RESULTS: In controls fetal serum beta(2)-microglobulin had a mean value of 3.4 mg/L (95% data intervals 2.0 to 4.9) and did not correlate with gestational age. In the 14 fetuses with urinary tract anomalies beta(2)-microglobulin levels were increased overall compared with controls (median Z score 1.7, range -0.1 to 9.2), and this was also the case in the five fetuses with unilateral renal disorders (median Z score 1.7, range -0.1 to 3.8) and in a fetus who underwent vesicoamniotic shunting and had normal renal function at birth. Serum beta(2)-microglobulin was normal in 4 fetuses with bilateral urinary tract obstruction and normal function at postnatal follow-up and also in 1 of 5 fetuses with renal failure. In fetuses with bilateral uropathy urinary sodium correlated with serum beta(2)-microglobulin levels. CONCLUSIONS: Increased values of serum beta(2)-microglobulin in fetuses with urinary tract anomalies indicate an impaired glomerular filtration rate. Thefinding of raised concentrations in fetuses with unilateral damage suggests that the compensatory role of the normal kidney is not completeduring intrauterine life. Larger series are required to ascertain whether fetal blood sampling is warranted in the antenatal investigation of renal function, especially in view of the close correlation betweenurinary sodium and serum beta(2)-microglobulin levels in fetuses withbilateral obstruction.
