Traumatic bilateral ureteric rupture in two dogs

Abstract

Two cases of bilateral ureteric rupture in dogs are reported. Both dogs were presented following road traffic accidents with signs of depression and abdominal distension. Both animals were azotaemic and abdominal fluid analysis was consistent with uroabdomen. In case 1, the injuries affected the proximal portion of both ureters and the dog was euthanased. In case 2, the ruptures were located more distally and a ureteroneocystostomy was performed, with contralateral ureteronephrectomy. This dog is clinically normal 16 months postoperatively.

The impact of surgical timing and intervention on outcome in traumatized dogs and cats

“…Many injuries can occur after blunt trauma including diaphragmatic hernia (DH), hemoperitoneum, and appendicular or axial fractures . The forces created during these injuries can cause devastating injuries and death, with an overall mortality rate of 10%–12% in canine patients .…”

“…Of these, 3 were specifically related to chronic DH, 6 are primarily imaging studies, and 3 are related to specific treatment modalities . Of the remaining 10 reports, 7 are case reports, 1 is a case series with 3 cats, and 2 are retrospective studies . These 2 studies include data from 126 cases (63 cats and 63 dogs) .…”

A clinical review of pathophysiology, diagnosis, and treatment of uroabdomen in the dog and cat

“…Uroabdomen in dogs and cats is most often associated with vehicular or blunt trauma to the abdomen or pelvis. The urinary bladder is the most common site of rupture . A retrospective study of uroperitoneum in 26 cats documented uroabdomen secondary to blunt abdominal trauma in 13 cats, of which 11 had a ruptured bladder.…”

“…If a ureteral rupture does occur, it most often occurs in the proximal portion . A case report published in 2006 documented 2 dogs that developed bilateral ureteral ruptures from motor vehicular trauma . Another retrospective study highlighted 10 animals with traumatic rupture of the ureter, of which 8 had sustained motor vehicular trauma …”

“…Stricture formation is a common complication following ureteral procedures especially in small patients . A ureteronephrectomy is an option if the ureter is severely damaged or if complications have occurred with a previous ureteral surgery …”
