Sonographic diagnosis of intestinal obstruction in the dog.

Ultrasonography was performed on 44 dogs to decide whether small bowel obstruction was present. The sonographic criteria for small bowel obstruction were (1) the presence of pendulous movement of the ingesta inside the dilated bowel, (2) observation of invaginated intestines or an ingested intraluminal foreign body, (3) observation of non-uniform peristaltic activity of the dilated intestines, or (4) observation of akinetic intestinal loops together with abdominal fluid accumulation. By using these criteria, obstruction was correctly diagnosed by ultrasonography in 11 of the 13 dogs with mechanical ileus, and obstruction was correctly excluded in 29 of the 31 non-obstructive cases.

Ultrasonographic study of feline lower urinary tract diseases: 32 cases.

The objective of the study was to describe the ultrasonographic findings of urinary bladder urolithiasis and to determine the diagnostic value of the technique in feline lower urinary tract diseases (LUTD). Physical examination of the urinary system and routine clinicopathological analysis of the blood and urine were performed on 32 cats presented with clinical symptoms of LUTD. Cystosonography was done on all of the cats, while plain radiography was performed on 8 and double contrast cystography on 2 cats.
