The objective of this study is to evaluate the impact of SWL application on kidneys in stone patients on oxidative stress parameters in 24-h urine. The study included 20 patients scheduled for SWL. total antioxidant capacity (TAC) and total oxidant status (TOS) measurements were made on 24-h urines of the patients before and after SWL. The oxidative stress index (OSI) was calculated based on these values. Following SWL, while TOS increased in 24-h urine (p = 0.006), TAC remained unchanged (p = 0.312). OSI increased following the procedure (p = 0.004). SWL application disrupts the oxidant/antioxidant balance in favor of oxidants, which leads to oxidative stress. TOS, TAC and OSI may be useful in the determination of the existence of oxidative stress following SWL.eninfo:eu-repo/semantics/closedAccessSWLOxidative stressTotal oxidant statusTotal antioxidant capacityOxidative stress IndexArticle41213714110.1007/s00240-012-0537-42-s2.0-8488091822223503875N/AWOS:000318336500007Q4
