Next generation sequencing in patients with nephrolithiasis: how does it perform compared with standard urine and stone cultures?

NGS has a higher detection rate of microorganisms than standard culture for both preoperative urine and stone cultures. Voided NGS was the most sensitive in predicting a positive Stone sample, but the specificity and PPV were, overall, low. Further correlation of NGS microorganism detection with patient outcomes will determine which clinical situations may benefit most from NGS versus standard culture in patients with urinary-tract stones.
