ABSTRACT
OBJECTIVE@#Urolithiasis, a common problem in medicine, poses a significant burden with prevalenceof 1-15%. Potassium citrate therapy has become one of the cornerstones of medical stone managementwith hypocitraturia being the most common metabolic problem in stone formers. The authorsdetermined the effects of potassium citrate on urinary metabolic profiles and its impact on stoneburden among Filipino stone formers.@*PATIENTS AND METHODS@#This is a prospective, cohort study in patients seen at the UST Hospital between2016 and 2018. Twenty-four hour urine citrate levels, stone sizes and urine pH pre-therapy and post-therapy were analyzed.@*RESULTS@#Significant changes in urinary citrate, pH and stone sizes were noted as soon as 3 months afterthe onset of therapy. These changes included increase in urinary pH (6.1 to 6.7; p=0.001), increase inurinary citrate (109.1 to 253.4mg/day; p<0.001) and decrease in stone size (0.56 to 0.37cm; p=0.037).The changes in the urine citrate and the changes in the stone size were not correlated using the Pearsoncorrelation scatter plot.@*CONCLUSION@#Potassium citrate therapy provides a significant alkali and citraturic treatment among Filipino stone formers. However, there is no significant correlation between changes in stone size and changes in urine citrate level.
