OVERVIEW
Occurrence of a urolith (calculus) within a ureter; most ureteroliths originate in the renal pelves and so commonly occur in association with nephroliths. Most uroliths that enter the ureter continue to the bladder without impedance, but uroliths may cause partial or complete obstruction of the ureter, resulting in dilation of the proximal ureter and renal pelves and subsequent destruction of renal parenchyma.
SIGNALMENT
Dogs and cats
Breed, age, and sex predispositions vary with type of nephrolith.
