When does gall bladder develop in fetus?
The fetal gallbladder evolves from a ventral outpouching off the caudal portion of the embry- onic foregut during the fourth week of gestation. At approximately 12 weeks gestation, the hepatic cells begin to produce bile, which passes through the bile duct to the duodenum by 13 weeks GA.
Can you see gallbladder on fetal ultrasound?

Increased hormones during pregnancy can cause higher cholesterol levels and delayed gallbladder emptying, which can lead to formation of gallstones. Nearly 8% of pregnant women form new gallstones by the third trimester, but only about 1% have symptoms.
Why would gallbladder not show up on HIDA scan?
GB not visualized: If the gallbladder is not visualized within 4 hours after the injection it indicates that there is either cholecystitis or cystic duct obstruction. HIDA scan for acute cholecystitis has a sensitivity of 97%, Specificity of 94%. Tracer not visualized in intestines means common bile duct obstruction.
What is gallbladder ultrasound?
A gallbladder ultrasound is a noninvasive and typically painless examination used to diagnose conditions related to the gallbladder. Unlike X-ray, ultrasound does not use radiation.

What is normal size of bladder in fetus?
Volume = 10ml at 32 weeks and quadruples by term. Diameter = 2cm (second trimester) and 3cm (third trimester). Significant increase in bladder length with CRL (1). At 10-14 weeks of gestation fetal bladder is <6mm and bladder/CRL ratio is <10% (1).
What is the normal size of the gallbladder?
It functions to accumulate and concentrate bile between meals. The normal adult gallbladder measures from 7-10 cm in length and 3-4 cm in transverse diameter 6. The gallbladder communicates with the rest of the biliary system by way of the cystic duct, with bidirectional drainage of bile to and from the common hepatic duct.
