Traumatic Injuries of the Urogenital System

Traumatic bilateral ureteric rupture in two dogs

“…Biochemical analysis of abdominal fluid is crucial in making a definitive diagnosis of uroabdomen. In such cases, comparison of the abdominal fluid creatinine concentration to that of serum consistently reveals a higher level in the abdominal fluid from contemporaneous samples (Burrows and Bovee 1974, Bjorling 1984, Aumann and others 1998, Schmiedt and others 2001, Gannon and Moses 2002). It should be noted, however, that in the majority of dogs with abdominal fluid due to causes other than uroabdomen, the abdominal fluid:serum creatinine concentration ratio (AFCr:SCr) is also elevated, albeit to a lesser degree (Schmiedt and others 2001).…”

“…However, when there is bilateral injury, other surgical options must be considered. Avulsion of the ureter from the kidney may be treated by re‐implantation into the renal pelvis (Bjorling 1984, McLoughlin and Bjorling 2003), but this is technically difficult and in most cases a nephrectomy is required (Bjorling 1984, Gannon and Moses 2002). Mid‐ureter injuries can be re‐anastomosed, but even when a stent is placed to decrease contact of urine with the suture line, stricture formation is still common (McLoughlin and Bjorling 2003).…”

“…Mid‐ureter injuries can be re‐anastomosed, but even when a stent is placed to decrease contact of urine with the suture line, stricture formation is still common (McLoughlin and Bjorling 2003). Neoureterocystostomy is the preferred treatment for distal ureteric injury (Bjorling 1984, McLoughlin 2000) and was successfully combined with a contralateral ureteronephrectomy in case 2. Excessive tension can be avoided by fixing the associated kidney in a more caudal position (renal decensus) and/or fixing the bladder in a more cranial position (psoas hitch procedure or psoas cystopexy) (Bjorling 1984, McLoughlin and Bjorling 2003).…”

A tube cystopexy gives the additional benefit of being able to monitor postoperative urine production.…”

Urethral Polyps in Vietnamese Pot-Bellied Pigs

“…Urethral damage may also be induced by repeated urethral catheterization. 1 This conceivably could be more of a problem in animals whose lower urinary tracts have anatomical structures which interfere with the successful passage of the catheter into the bladder. 3,4 Two other published papers have reported urethral obstruction at the level of the urethral recess.…”
