Urine test
pH 9.0   SG 1.005   Nitrite +, Protein 3+, Blood 4+, Bacteria 2+WBC 180  RBC >2250
Crystals Nil
Casts  Granular cast occasional

Aug 2, 2012 stone analysis
Calcium stone trace
Phosphate stone +
Oxalate stone trace
Magnesium stone +
Ammonia stone +

This case confirms what is known. No crystals inside the urine does not mean no struvite stones.
Alkaline pH + bacteria (urease) + bacteria  leads to formation of MAP (struvite stones).


Sep 20, 2012. Review by me. I asked Vet X to put in writing that therapeutic diet S/D has been advised at least from 1- 3months. If there is recurrence, Vet X cannot be blamed. Advice on monthly
urine analysis. Preferably X-rays 3 monthly.

The children came to buy 2 cans of S/D recently. There need to be more rigorous follow up by Vet X and documentation of advices on medical records in case of recurrence as surgical costs can be very high and owners can be very unhappy when there is a recurrence. Sometimes, they just euthanase the dog to save on costs of surgery.
