Correlations Between the Composition of Moroccan Urinary Stones and the Risk Factors (Food Habit)

The aim of this study is to characterize and to analyze the likely factors to influence the composition of the Morocco urinary calculi, we took a study between July 2002 and June 2007 with 283 lithiasis patients that gave their sample (stone) for analyzes by infrared spectroscopy and replied to the questionnaire. Different informations were recorded: epidemiological characteristic (sex, age, residence zone and profession), food habits (tea; rich products in calcium, oxalate, animal proteins and spicy meals) and consumption. The results show: a strong liaison between the different studied factors and the stone mainly composed of Weddelite, Whewellite and uric acid; the age effect on the stone mainly composed of Weddelite and uric acid was confirmed. Significant correlations were noted, positive between the stone mainly composed of Weddelite and the consumption of oxalate and negative between the stone mainly composed of calcium phosphate or magnesium ammonium phosphate and tea and spicy meals. This research shows equally that the consumption of the rich products in oxalate is frequents and that the consumption of the rich products in calcium is weak. This nutrition type would be responsible to the preponderance of the stone calcium oxalate (Whewellite, Weddelite) observed in our country.
