Introduction

• Cause: blunt abdominal trauma, urethral obstruction, neoplasia, iatrogenic.
  In all cases of traumatic injury warn owner of potential complications at time of injury.
• Signs: anuria/hematuria, frequent unsuccessful attempts to urinate, stranguria, abdominal distension (later), vomiting.
• Diagnosis: clinical signs, contrast radiography, serum biochemistry abnormalities, sometimes presence of uroabdomen.

Pathogenesis

Etiology

• Blunt abdominal trauma: road traffic accident (RTA), kick, penetrating abdominal trauma Abdomen: trauma.
• Urethral obstruction Urethra: obstruction : urolithiasis Urolithiasis , neoplasia Bladder: neoplasia , bladder retroflexion.
• Neoplastic infiltration.
• Iatrogenic (surgical misadventure, urethral catheterizaton, manual evacuation).

Pathophysiology

• Progressive elevation blood urea/creatinine.
• Chemical peritonitis: dehydration, hypochloremia Hypochloremia , hyponatremia Hyponatremia , hyperkalemia Hyperkalemia , anemia Anemia: overview , hypoproteinemia Hypoproteinemia. May take 2-3 days to develop.
