Ureters and Bladder
Liver
URETER
Anatomy: Pelvis
Dilated calyx
Vertebral bodies
Dilated ureter
Dilated renal pelvis
Reverberation artifact
Normal left ureteral jet
Right UVJ stone causing twinkling
artifact, with absent ureteral jet
Mild hydronephrosis
Significant urothelial thickening
(Top) Longitudinal transabdominal grayscale ultrasound of the right kidney shows a dilated pelvicalyceal system and proximal ureter.
The ureter is normally not visible on ultrasound unless it is dilated as seen here. (Middle) Oblique color Doppler ultrasound of the
suprapubic region shows calculus at the right ureterovesical junction (UVJ) causing twinkling artifact with absent ureteral jet. Normal
left ureteric jet is seen. (Bottom) Longitudinal transabdominal ultrasound of the left kidney shows significant urothelial thickening of
the pelvicalyceal system and proximal ureter in this patient with known extramedullary hematopoiesis.
