On mm'den küçük Proksimal Üreter Taşlarının Tedavisinde Fleksibl ve Semirijid Üreteroskopi Kullanımının Karşılaştırması.

Background: In this study, we aimed to investigate the treatment outcomes and safety profile of flexible and semi-rigid ureteroscopy performed for the treatment of proximal ureteral calculi smaller than 10 mm. Materials and Methods: Patients who underwent ureteroscopy in our clinic between 2013 and 2019 for proximal ureteral stones smaller than 10 mm were assessed retrospectively. Patients were divided into two groups with regard to ureteroscopy type. Each group were compared in terms of demographic, operative and postoperative parameters and success rates. Results: No differences were found between flexible (266) and semirigid ureteroscopy (116) groups in terms of demographic features and stone sizes. Mean operative times were 45±10.9 minutes and 37.2±10.2 minutes for flexible and semi-rigid ureteroscopy groups, respectively. Success rates were %91,4 (266/243) in flexible ureteroscopy group and %79.3 (116/92) in semi-rigid ureteroscopy group. No differences were detected in terms of complication rates (10.5% in flexible, 16.4% in semi-rigid group). Conclusion: Given its high success rate, flexible ureteroscopy appears to be more advantageous than semirigid ureteroscopy for treatment of proximal ureteral stone smaller than 10 mm.
