Mesane Tümörü Rezeksiyonunda Karl Storz ve Olympus Bipolar Rezeksiyon Sistemlerinin Karşılaştırılması.

Background: In this study, we aimed to compare the perioperative outcomes and complications of Olympus and Karl Storz bipolar transurethral bladder resection in the treatment of bladder tumors in non-invasive bladder cancer patients. Materials and Methods: After obtaining approval from the Ethics Committee (Decision No. 2023/5-17), all patients who underwent transurethral bladder tumor resection using Olympus and Karl Storz bipolar systems between January 01, 2019 and February 28, 2023 were evaluated. The demographic data of the patients, transfusion requirement, tumor size, and perioperative complications were compared. Results: It was observed that out of the 75 patients included in the study, 45 were operated on with Olympus, and 30 were operated on with Karl Storz. In the Olympus group, the change in hemoglobin (hgb) was found to be 1.11±0.61 gr/dl, while in the Karl Storz group, it was 1.35±0.82 gr/dl, and no statistically significant difference was observed (p= 0.180). Tumor size was 3.20±1.55 cm in the Olympus group and 4.20±2.79 cm in the Karl Storz group. Similarly, no statistically significant differences were found between the two groups in terms of obturator reflex, presence of bladder perforation, blood transfusion, and postoperative clot retention. Conclusions: The use of both bipolar systems' technology is safe and effective in the transurethral resection of non-invasive bladder cancer. [ABSTRACT FROM AUTHOR]
