Sonography of the Ureters

normal ureters are not imaged with sonography due to

their small size

when enlarged and distended with urine, the ureters will appear

as anechoic, tubular structures

whenever identified with sonography, the ureters should be thoroughly evaluated for

obstructive processes

the ureteral jets result form

urine being forced into the urinary bladder from the ureters

imaging of ureteral jets is performed to demonstrate

ureteral patency in suspected cases of urinary obstruction

urinary jets typically occur

at least once every minute

color Doppler is employed over the

inferoposterior aspect of the urinary bladder in the area of the ureteral orifices and trigone
