Is UT2 HBT and gallbladder ultrasound the same?

No, UT2 HBT (urinary tract two hour holding bladder test) and gallbladder ultrasound are not the same. UT2 HBT is a urodynamic test that measures the pressure and flow of urine in the bladder, while a gallbladder ultrasound is an imaging test that uses sound waves to create pictures of the gallbladder.
