Findings
Orthogonal radiographs of the abdomen are available for interpretation.
Overall there is moderate loss of serosal detail within the abdominal cavity. A wet hair artifact is noted mostly dorsal to the patient.There is no evidence of free abdominal gas. In the abdominal cavity, the colon contains a moderate amount of gas. The remainder of the small intestinal tract is difficult to individualize. Both kidneys are visualized and considered to be within normal limits. The outline of the bladder is faintly appreciated. In the soft tissues caudal to the ischium, ventral to the tail, there is a moderate amount of mineralized material arranged in a linear pattern. This measures about 23 mm in length. In the caudal aspect of the thorax are available for interpretation, there is a mild amount of interstitial pattern.
Impression: 1. Mineralized structure superimposed with the soft tissues caudal to the ischium. These are likely to represent urethral stones. 2. Loss of serosal detail within the abdominal cavity. This could be secondary to the previously performed abdominal surgery; however, the underlying presence of free abdominal fluid secondary to peritonitis or uroabdomen cannot be ruled out. For further evaluation abdominal ultrasound could be useful.
Diagnosis
Urethral stones likely resulting in urethral obstruction
