Original publication title: Spontaneous retrograde movement of ureteroliths in two dogs and five cats.
Plain-English summary
Two dogs were treated for ureteroliths, which are stones in the ureters that can cause serious urinary issues. During their evaluation, it was found that some of these stones moved back up towards the kidneys, which could improve kidney function but made surgery more complicated. Unfortunately, medical treatments didn't work, and both dogs needed surgery to remove the stones. The unexpected movement of the stones made the surgical process more challenging, but the surgery was ultimately performed to address the issue.

Abstract
CASE DESCRIPTION: 2 dogs and 5 cats were evaluated for treatment of ureteroliths. CLINICAL FINDINGS: Spontaneous retrograde movement of 1 or more ureteroliths was detected by radiography, ultrasonography, fluoroscopy, and a combination of fluoroscopy and ultrasonography. The ureteroliths moved retrograde up to 4 centimeters. Retrograde movement of ureteroliths into the renal pelvis resulted in improved renal function in some patients but made complete surgical removal of all uroliths more difficult. TREATMENT AND OUTCOME: Medical management was not successful, and ureteroliths were surgically removed. Surgical management of ureteroliths was complicated by retrograde movement of ureteroliths in the perioperative period. CLINICAL RELEVANCE: Ureteroliths can move retrograde within the ureter and even back into the renal pelvis. Retrograde movement of ureteroliths may make surgical planning more difficult.
