HOW TO PREVENT RECURRING URINARY STONES?


In Sep 2017, the owner consulted Vet 1.
Dysuria and dripping urine. Bladder moderately enlarged. No pain.
Operated by Vet 1.
X-rays
One large stone had both struvite and ammonium urate compostion. Multiple small bladder stones have 100% ammonium urate.

On Hill's U/D diet for some time. Fed commercial canned food later.

2 YEARS HAVE PASSED. DYSURIA AGAIN

July to Oct 2019.
Dysuria
Urine test - amorphous phosphate +
X-rays
Owner does not want surgery to remove stone as the dog is very old
Urinary catherisation. Goes home a few days. Bladder blocked. Came back. Repeat urinary catherisation.

Urethral stone blocking the flow of urine. The dog has to come every few days
to get the stone pushed by into the bladder so that he can pee. Finally,
the owner consented to urethrostomy (an opening behind the os penis). Now he can pee normally.

CONCLUSION
The owner was worried about the dog dying under general anaesthesia during surgery to remove the stone. As she had to come every few days to "unblock" the bladder via urinary catheterization, she finally consented to a urethrostomy (opening behind the os penile bone) to let the small stone flow out of the urethra. As at Nov 23, 2019, the dog can pee normally.
