calcium oxylate stone removal surgery

Sophie

my dog just had surgery to remove calcium oxylate stones about 3 weeks ago. she healed up nicely, and her attitude is great...she's active, eating fine, etc. However, she is still straining to urinate constantly! She walks and squats, and she is having accidents in the house. My doctor put her on Baytril (2nd round) after finding some bacteria over a week ago, but she isn't improving. Today, we did another U/A, and found some abnormal looking renal tubular cells, no bacteria, and 0-4 hpf RBC's. We sent it off to be cultured, but my concern is that it is something more serious? I am a CVT, and would love any suggestions, as my doctor is stumped as to what would make her strain like she is... (She is a maltese). Please help!! thanks,, Krista

  Krista, sorry to hear your dog is still having signs. Has her urethra been palpated?  Were post op radiographs taken to make sure that all the stones were removed?  In females, it's less likely that one will get trapped in the urethra, but I've seen it happen twice.  Ended up having to fish one of them out with a scope.  Ultrasound would be my next diagnostic test to evaluate the kidneys, bladder, and urethra. If your dog is older cancer is a concern. Stump pyometra can also cause urinary signs and ultrasound can also be diagnostic in that instance.  Hope this helps.

  Thank you for your suggestions, I will definately pass them on to my Vet. Today he put her on more antibiotics and Prednisone. The U/A came back neg bacteria, but RBC's and WBC's were present. So maybe there is just still some irritation from the inflammation from the surgery, and the earlier bacterial infection? (hence the pred). I had read somewhere that Predisone as well as some other steroids can sometimes be contraindicated in a dog that has developed calcium Oxalate stones and crystals..Do you know about that? It sounds to me like an ultrasound would be the next step. Thanks again, krista CVT

  Krista,

  Did you get the second response and article I attached?   Long term prednisone usage can indeed induce an increased ca++ excretion from the kidneys worsening chances of stone formation.  Short use, low dose, is less concerning.  Please let me know if you got the article I sent on calcium stone formation. It showed as posted.  Ugh!
