Association between urinary lithiasis, other than struvite by crystallography and non-ureolytic bacteria.

The relationship between urinary tract infection caused by urease-producing bacteria and lithiasis due to struvite stones is well established in the literature. However, there is limited knowledge on whether non-urease producing bacteria can also promote crystallization. In our study, we analyzed the association between urinary lithiasis, other than struvite by crystallography and non-ureolytic bacteria, in 153 patients who underwent surgery for urinary stone.
