Dog UTI symptoms gone. Is an X-ray for bladder stones still needed?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | spayed | 9 years and 10 months old | 60 lbs

My dog was diagnosed with a Struvite UTI infection and was prescribed clavaseptin twice a day for 14 days. After 3 doeses she completely improved and stopped squatting with nothing coming out and her urine is no longer cloudy. We had a urinalysis done and culture with no crystals present. The vet recommended another week of antibiotics & xray to see if there are stones in her bladder. Is the xray necessary at this point? She has been on 2 weeks of antibiotics now and and is showing no signs.

Yes urinary stones can be present even though there are no signs at the moment, as antibiotics could possibly mask the signs. I would suggest either to stop antibiotics and see if the signs reoccur or to take an x-ray and rule out radiopaque stones. Alternatively ultrasound can be performed to rule out ALL type of stones (some of them cannot be seen with x rays). Hope this answer was helpful, but please do not hesitate to contact us again on the forum or by requesting a consultation if you have any more questions or to discuss it any further.

    I'm glad to hear that Romeo's UTI cleared up! In some (but certainly not all) dogs with bladder stones, crystals may be seen microscopically with a urinalysis. However, for some dogs with bladder stones, crystals don't pass through the urine and only form around bladder stones. Male dogs uncommonly get UTIs, so given Romeo's recent history, it sounds as though it's worth asking your vet about taking x-rays of his bladder to rule out the possibility of bladder stones. The most common types of bladder stones (struvite and calcium oxalate) are visible with x-rays. I hope that everything goes well!

    I am very sorry to hear about your dog. The X-ray is slightly pixelated on our side so difficult to fully interpret but it looks like there are stones in the bladder and probably also the urethra (tiny tube that connects bladder to the outside). The stones in the urethra were likely causing blockage leading to inability to urinate. Sometimes we can pass a urinary catheter to relieve the blockage temporarily by pushing the stones back into the bladder, where they can be removed surgically, and the catheter can allow urination until that time. In some cases however the stones will not allow passage of the catheter in which case surgery may be much more complicated. I cannot speak to the circumstances in your dog or the hospital capabilities. I would recommend making an appointment to talk to the vet about what happened to have closure. I am sorry for your loss.
