This study sought to establish normal dimensions of the fetal gallbladder
throughout pregnancy. The gallbladders in 300 normal fetuses between 15 and
40 weeks of gestation were measured prospectively for length,
anteroposterior dimension, and transverse dimension. The gallbladder
length, anteroposterior diameter, and transverse diameter have a linear
relationship with gestational age between 15 weeks and 30 weeks of
gestation, after which a plateau is observed. Calculated gallbladder area,
volume, and sagittal perimeter have similar rates of growth in utero. The
normative dimensions we have established for the fetal gallbladder
throughout pregnancy can be expected to serve as a basis against which
aberrant growth can be evaluated prenatally.
