The nutritional impact upon the development and treatment of the phosphate-ammonium-magnesium urolithiasis

Abstract

The urolithiasis in cats represent 15% of the total cases with UTD (Urinary Tract Disease) to this species. Out of these, 50% are proving to be composed of phosphate ions, ammonium and magnesium. To date, a multitude of factors that could be leading to the development of this stones are known. However, their treatment and control still representes a medical challenge. The study has been done on a number of 8 cats, 4 castrated males, 2 intact males and 2 sterilised female. The impact of the food that had been fed to the subjects had upon the development of the phosphate-ammonium- magnesium uroliths, as well as the impact of the post-diagnose diet, had been carefully analysed. As a result, the excess of 5 risk factors in the struvite lithogenesis from their daily diet before the diagnosis. Their values had been compared with those found in the speciality literature for the same risk threshold. From the perspective of this pathology's development, the results have revealed in all eight cases an excess of calculogenic factors in their pre-diagnose diet. However, it did not reveal an influence over the struvite disolution. The next step was to study the treatment's evolution from using two commercialy available products, fomulated for the treatment and prevention of the studied urolithiasis. The results have concluded the efficacy in the complete dissolution of the struvite of just one of them.
