Figure 10.51. Urolith in distal ureter. Transverse B-Mode (left) and Power Doppler (right) sonographic images obtained at the bladder trigone of a cat with right-sided hydronephrosis. A hyperechoic structure consistent with a calculus (C) is lodged in the distal portion of the right ureter. Urine jet (UJ) is only visible from the left ureter. co-authored by Marc-André d'Anjou and Dominique Penninck
