title: Incomplete urethral obstruction associated with dilatation of the urethra, cystitis, and pyelonephritis in a Vietnamese pot-bellied pig.
abstract: A 2-year-old castrated male vietnamese pot-bellied pig examined because of stranguria was found to have severe dilatation and inflammation of the pelvic portion of the urethra accompanied by cystitis and pyelonephritis. The pig had apparently had chronic inflammation of the urinary tract that eventually progressed to incomplete obstruction of the urethra. However, the initial cause of the urinary tract inflammation could not be determined. Possible causes included chronic bacterial infection, traumatic injury during urethral catheterization, and injury to the urethral mucosa secondary to extreme acidification of the urine.
