Comparison of Flexible and Semirigid Ureteroscopy Usage for Treatment of Smaller Than Ten Millimeter Proximal Ureteral Stones

Öz

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.

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

Öz

Amaç: On mm ve altındaki proksimal üreter taşlarında cerrahi gerektiren durumlarda fleksibl üreteroskopi ve semirijid üreteroskopi kullanımı sonuçlarının ve güvenilirliğinin değerlendirilmesi amaçlanmıştır.

Materyal ve Metod: Kliniğimizde 2013-2019 arasında 10 mm’ den küçük proksimal üreter taşı nedeniyle opere edilen hastaların verileri retrospektif olarak değerlendirildi. Hastalar cerrahide kullanılan üreteroskopi tipine göre fleksibl ve semirijid üreteroskopi grubu olarak ikiye ayrıldı. Her iki grup demografik özellikler, operatif ve postoperatif sonuçlar ve başarı oranları açısından karşılaştırıldı.

Bulgular: On mm’den küçük proksimal üreter taşlarının cerrahisinde kullanılan üretroskopi tipine göre, toplam 382 hastada fleksibl (266) ve semirijid (116) üreteroskopi grupları arasında demografik özellikler ve taş boyutu arasında fark bulunmamaktaydı. Ortalama operasyon süresi fleksibl üreteroskopi grubunda 45±10,9 dakika iken semirijid üreteroskopi grubunda 37.2±10.2 dakikaydı (p= 0.001). Fleksibl üretroskopi grubunda %91,4 (266/243) ve semirijid üreteroskopi grubunda %79,3 (116/92) başarı oranına ulaşıldı (p= 0.001). Komplikasyon oranları açısından fleksibl (%10,5) ve semirijid (%16,4) üreteroskopi grupları arasında fark yoktu.

Sonuç: Küçük proksimal üreter taşlarında cerrahi gerektiren durumlarda fleksibl üreteroskopi kullanımı yüksek başarı oranları ile semirijid üreteroskopi kullanımına göre daha avantajlı gözükmektedir.
