Correlations between stones composition, dietary and comorbidities context of the lithiasic patient.

The incidence of nephrolithiasis is in full expansion, its etiology being frequently associated with lifestyle changes. The objective of this retrospective study, carried out between April and December 2019, was to identify the correlations of the known lithogenic factors with the chemical structure of the calculi in the patients from the North-Eastern region of Romania. The results obtained after the data analysis of our LAMPA questionnaire (L - liquids, A - antecedents, M - medication, P - associated pathologies, A - aliments) made in evidence a statistically relevant relationship between the heredocollateral history of lithiasis and calcium oxalate dihydrate (COD) calculi, hypertension and calcium oxalate monohydrate (COM) stones, uric lithiasis and diabetes, COD, and obesity, between predominantly uric lithiasis and meat or meat-derived products consumption, between frequent potato consumption and COD stones and the frequently consume of dairy products and predominantly COM calculi. The authors concluded that the use of a complex questionnaire, like LAMPA, together with Fourier-transform infrared (FTIR) spectroscopic and morphological analysis are essential steps for developing an efficient metaphylaxis.
