Uroliths in a dog
Lady, a 12 year old female Labrador was presented in distress straining to pass lots of small volumes of bloody urine. The problem had been going on for a few months but was getting worse.
Her vitals were normal but a large firm bladder was palpable. We suspected she may have several stones (uroliths) in the bladder.
Xrays showed a huge number of uroliths in the bladder. Blood tests showed her kidneys and other organs were ok.
We placed Lady on an intravenous drip and started her on some strong antibiotics (Enrofloxacin). She was premedicated, then given an injection of short acting anaesthetic (Alfaxan) then placed on Isoflurane gas anaesthetic.
Upon opening the bladder through an incision (cystotomy), we could see large numbers of uroliths. We removed the uroliths and found Lady had a much thickened bladder wall as a result of the chronic stone irritation and suspected secondary bacterial infection in the urine. We flushed the bladder with saline several times to make sure we had all the stones out.
We closed the bladder wall using a double layer of inverting stitches (Connell-Cushing pattern) and flushed the surrounding area with saline and an antibiotic flush (Ampicillin).
We closed the abdominal wall and skin. Lady made a quick recovery and was discharged 2 days later. The stones were analysed and found to be made of struvite, so Lady was placed on a special prescription diet (Hills S/D) to prevent them coming back again.
