Today’s case is a 6-year-old male neutered domestic short hair cat that began growling, becoming restless, and a marked change in behavior. He had vomited several times.
Initial projections reveal a intravenous catheter within the right medial saphenous vein terminating within the caudal vena cava. Bilaterally the kidneys are mildly enlarged. Contrast material was administered intravenously. The renal pelves are mildly distended. The proximal ureters are mildly distended but taper. No obstructive process is identified.
Bilateral proximal ureteral dilation. Differentials include pyelonephritis or a previous obstructive process that has now passed.
Although no definitive cause for the ureteral and/or urethral obstruction was identified, the enlarged renal pelves and ureters as well as the enlarged urinary bladder were suggestive. Renal values improved over the next several days, and the cat was able to urinate once the urinary catheter was removed. Final diagnosis of feline idiopathic cystitis.
One of my patient is a male husky dog with 6 years old and about 31kg body weight. 3 years ago, while I was examine the patient for first time for another resoan, I detected the left ureter was dilated up to 15mm! No sign of ureteral calculi was seen with ultrasound and x-Ray studies. Peristaltic movements of ureter was exaggerated. Renal RI was within normal range and no sign of sub-capsular effusion was seen in left kidney. The right kidneys and related ureter was normal. Although no clinical sign of abnormality was detected in clinical examinations of urinary system. Repeat ultrasonography in last week shows the same findings!
– What is your opinion about this unilateral dilation of ureter?
Hello, Allison.
I have two questions regarding this case.
All the findings are clear, but for me, the ending of one of the ureters from the lateral view is too caudally. And there is also a little stream of CM within the uretra. For me, this is a big suggestion for ectopic ureter. However, I would be not sure with radiographs only. Did you perform US, CT or cystoscopy in this cat? My second question is about the descendent colon. From VD view it is dislocated to the right. Could this be because of the bladder distention?
Thank you for your answer.
