It reduces fertility with significantly changes a woman's quality of life. Laparoscopy proved to be standard treatment for endometriosis, particularly for endometriomas. Disruption of oxidative stress balance has been put in the focus in the recent studies. The aim of the study was to follow the impact of cystectomy and compare bipolar and laser electrocoagulation on prooxidative stress biomarkers and antioxidative capacity. A total of 60 women with diagnosed endometriosis were included in the study and divided in two groups according to laparoscopy treatment with different energy sources for electrocoagulation. Prooxidative parameters (superoxide anion radical (O2-), nitrites (NO2-), hydrogen peroxide (H2O2), index of lipid peroxidation measured as TBARS) and antioxidative defence system parameters (reduced glutathione (GSH), activity of superoxide dismutase (SOD), activity of catalase (CAT)) were determined spectrophotometrically before and after the surgery. The value of H2O2 was decreased in group treated with biporal electrocoagulation, while the value of GSH was increased in both groups. The value of O2- was significantly decreased in the group treated with laser while SOD activity was increased in the same group. The both methods had a similar effect on index of lipid peroxidase and reduced glutathione, but when it comes to the decreasing of harmful superoxide anion radical and increasing of SOD activity, laser electrocoagulation showed better outcome. The role of oxidative stress in both, understanding the pathogenesis of this disease and as a potential therapeutic target, is certainly of great importance.\nThis dataset contains biochemical and hormonal assay data comparing the effects of bipolar cystectomy and laser cystectomy on oxidative stress and endocrine function in human subjects. The study aimed to determine whether different surgical techniques influence oxidative stress and hormonal balance differently in the postoperative period.\nAuthors and Affiliations\nIgor Gogic¹², Vladimir Jakovljevic³⁴⁵, Marina Nikolic³⁴, Sasa Raicevic¹⁶, Aleksandra Stojanovic⁴⁷\n¹ Department of Gynecology and Obstetrics, Faculty of Medicine, University of Montenegro, Podgorica, Montenegro\n² Department of Gynecology and Obstetrics, Special Codra Hospital, Podgorica, Montenegro\n³ Department of Physiology, Faculty of Medical Sciences, University of Kragujevac, Kragujevac, Serbia\n⁴ Center of Excellence for the Study of Redox Balance in Cardiovascular and Metabolic Disorders, University of Kragujevac, Kragujevac, Serbia\n⁵ Department of Human Pathology, First Moscow State Medical University I.M.
