Rex, a 5 year old Border Collie had been off colour for a few days. He was frequently trying to urinate but was not producing a lot each time. On examination the vet palpated his bladder and felt it was quite full. The vet managed to get a small sample of urine to test on a dipstick, which showed that there were red blood cells and white blood cells present, which indicated that there was an urinary infection and some bleeding.
The vet suggested that as Rex was having difficulties, the best thing to do was to x-ray his bladder and catheterise him to obtain a urine sample. The vet was specifically looking for stones as they can cause a blockage preventing the patient from being able to urinate, but the x-ray showed that there were no urinary stones present. The vet then took a urine sample which was sent to an external lab for full analysis.
The vet suspected that the problem could be functional, so Rex was put onto some medication to help him urinate by himself and to clear the urinary infection. The next day Rex still had not urinated so was brought in to be catheterised. He then had to come in daily so that we could express his bladder.
After a week there was still no improvement so it was suggested that the owners learn how to catheterise him, so they were able to do it at home. He was also put onto some different medication to stimulate his bladder to contract to aid urination.
After almost two months of being on the medication and having to be catheterised regularly, Rex started to urinate by himself and the whole practice cheered!!
All was fine until several months later when Rex was straining frequently to pass both urine and faeces and he started to have accidents in the house overnight. As he had been doing well for a while, the owner was concerned that his previous urinary problems were recurring.
On examination the vet felt his bladder, which was empty, but slightly thickened and his prostate was enlarged. As Rex was still an entire male it was the hormone testosterone that was causing the enlarged prostate, so he was given an anti-testosterone drug to reduce the size of his prostate. But this was only a temporary measure and to fix the problem in the long run Rex would need to be castrated.
The owner collected a urine sample which was tested in house and showed that Rex had contracted another urinary infection so he was put onto another course of antibiotics.
After just over a week, Rex returned for a check up. He was a lot better and was no longer straining. However when the vet felt his bladder again, it was still quite thickened and felt gravelly so the vet suspected bladder stones.
On the x-ray the vet could see multiple stones visible in the bladder and the urethra. The next step was to operate and perform a cystotomy (an incision into the bladder) to remove the stones. First Rex had to be prepped for surgery which involved clipping his abdomen and cleaning it with skin disinfectant. He was then catheterised to make sure the bladder was empty before the vet could operate. He was then ready to be transported into theatre. The vet firstly made an incision into the abdomen so he was able to examine the area then enter into the bladder. The bladder stones were very small so the vet had to scoop out as many as he could and then a urinary catheter was placed to thoroughly flush the urethra and bladder with saline to ensure the majority had been removed. Once the vet was happy, the bladder then needed to be sutured, ensuring a tight seal to allow the bladder to heal properly. Rex was also castrated at the same time.
The bladder stones were sent to an external lab to be identified as Rex would need to go onto a specific urinary diet to prevent any further problems in the future.
Once the vet had sutured the bladder and the abdomen, Rex was put back into to his kennel to recover from the anaesthetic. He was allowed to go home later in the day on pain relief and a specific urinary diet.
The next day a nurse rang the owner to see how he was getting on. Rex was able to urinate well by himself and was enjoying the new diet which is always a bonus. But the poor owner was having problems with the buster collar as Rex was pulling all the tricks in the book to get the collar off!!
The results from the lab showed that the stones were struvite. They can be caused by diets high in protein and the pH of the urine also effects the formation of the stones. The urinary diet Rex had been put on is specially formulated to dissolve struvite crystals, therefore preventing the problem from recurring. He will need to have a repeat urine test in a month’s time to make sure that there are no crystals present.
Rex is now well on the way to recovery. He is much better and enjoying his walks again in the company of his friend Tessa who is also a Border Collie. But, unfortunately the squirrels short respite has ended as he has resumed chasing and growling at them up in the tree tops.
