A case of Atazanavir-induced renal lithiasis is presented. Atazanavir Sulfate is an HIV protease inhibitor, which is currently widely used in these patients. Atazanavir is a substance that has low solubility in water for pH values greater than 6 (it is maximum at pH 1.9 and zero at pH 6.8). Thus, the presence of Atazanavir acicular crystals in urinary sediments of patients taking this drug, as well as renal problems, has been frequently described [1-5]. The presence of these crystals in calcium oxalate stones has also been described. However, there are very few descriptions of lithiasis formed mainly by Atazanavir, such as is presented in this article.
