Comparison of the Karl Storz and Olympus Bipolar Resection Systems in Bladder Tumor Resection

Öz

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 sys-tems 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 Olym-pus, 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 signifi-cant 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 post-operative clot retention. Conclusions: The use of both bipolar systems' technology is safe and effective in the transurethral resection of non-invasive bladder cancer.

Mesane Tümörü Rezeksiyonunda Karl Storz ve Olympus Bipolar Rezeksiyon Sistemlerinin Karşılaştırılması

Öz

Amaç: Kasa invaze olmayan mesane kanserli hastalarda mesane tümörlerinin tedavisinde Olimpus ve Karl Storz bipolar transüretral mesane rezeksiyonunun perioperatif sonuçlarını ve komplikasyonlarını karşılaştırmayı amaçladık. Materyal ve metod: Etik Kurulu onayı (Karar No. 2023/5-17) takibinde, 01 Ocak 2019 ile 28 Şubat 2023 tarihleri arasında Olimpus ve Karl Storz bipolar sistemleri ile transüretral mesane tümörü rezeksiyonu yapılan tüm hastalar değerlendirilmeye alındı. Bulgular: Olimpus grubunda hemoglobin (hbg) değişimi 1,11±0,61 iken Karl Storz grubunda 1,35±0,82 olarak görüldü ve anlamlı istatistiksel fark görülmedi (p= 0,180). Tümör boyutu Olimpus grubunda 3,20±1,55 cm olup Karl Storz grubunda 4,20±2,79 cm olarak değerlendirildi. Benzer şekilde obturator reflex, mesane perforasyon varlığı, kan tranfuzyonu, postoperatif pıhtı retansiyonunda da istatistiksel olarak farklılıklar saptanmadı. Sonuç: Kasa invaze olmayan mesane kanserinin transüretral rezeksiyonunda bipolar teknolojinin kullanımı güvenli ve etkili bir yöntemdir. Her iki tekniktede mesane perforasyon oranı, postoperatif pıhtı retansiyonu, postoperatif hemoglobin düşüşü, obturator reflex oranı benzer bulunmuş olup, istatistiksel olarak fark görülmemiştir.
