(2018). Measuring urinary 8-hydroxy-2′-deoxyguanosine and malondialdehyde levels in women with overactive bladder. Investigative and Clinical Urology, 59(4), 252-256.https://hdl.handle.net/11494/2132Purpose: In this study, we aimed to explain the role of oxidative stress in women with overactive bladder (OAB) by investigating the levels of 8-hydroxy-2'-deoxyguanosine (8-OHdG), a marker of oxidative DNA damage, and malondialdehyde (MDA), an indicator of lipid peroxidation. Materials and Methods: A total of 90 women were included in the study: 45 female patients diagnosed with OAB at Hopa State Hospital Urology Polyclinic and 45 healthy women without any metabolic or neurologic disease. Levels of MDA and 8-OHdG were measured in 24-hour urine samples for all subjects. Results: Urinary levels of MDA and 8-OHdG were significantly higher in the OAB group than in the control group (p<0.001). A significant positive correlation (p<0.001) was found between the measurements of 8-OHdG and MDA. Conclusions: Oxidative stress may be important in the pathophysiology of OAB, because levels of 8-OHdG and MDA are increased. Increased levels of 8-OHdG may be due to damaged nuclear and mitochondrial DNA as a result of oxidative attacks caused by free radicals. Nevertheless, further randomized and prospective studies with larger patient populations are neededeninfo:eu-repo/semantics/openAccessAttribution-NonCommercial 3.0 United StatesLipid peroxidationOxidative stressUrinary bladderoveractive8OHdGArticle59425225610.4111/icu.2018.59.4.252Q2N/A
