Evaluation of neutrophil gelatinase-associated lipocalin, interleukin-18, and cystatin C as molecular markers before and after unilateral shock wave lithotripsy.

Objective: To investigate the impact of shock wave lithotripsy (SWL) on renal tissues using neutrophil gelatinase-associated lipocalin (NGAL), cystatin C, and interleukin 18 (IL-18) levels in serum and urine and to examine the relationship of these biomarkers with patient and calculus characteristics as well as SWL treatment parameters.

Materials And Methods: Thirty-seven patients with renal calculi were included in this study. Blood and urine samples were attained from each patient at 4 time points; immediately before SWL, 6 hours after, 3 days after, and 10 days after the SWL.
