Abstract

Objective: Cryoablation of renal tumors adjacent to the ureter or pelvicalyceal system carries risks forthermal injury of the collecting system. Although cold antegrade perfusion has been described for radiofrequencyablation, warm saline perfusion for renal cryoablation has not been well-characterized. The purposeof this study was to determine the safety and feasibility of antegrade and retrograde warm saline perfusionsduring percutaneous renal cryoablation.Material and methods: A retrospective review was performed on 136 patients treated with percutaneousrenal cryoablation at a single academic institution between 2009 and 2015. Six patients undergoing antegrade(n=3) or retrograde (n=3) warm saline perfusion for protection of the collecting system were identified.Warm saline was perfused through a 4 French nephrostomy tube in the antegrade technique and througha 6 French end-hole catheter in the retrograde technique. Outcome measures were tumor recurrence rates,success of urothelial preservation, hospital stay, blood loss and procedural time.Results: Four tumors were in the lower pole and two tumors in the middle pole. The mean distance fromtumor to ureter was 6.8 mm (0.8-11.5 mm) and no patient developed ureteral stricture. There was no tumorrecurrence at a median follow-up of 37.3 months (7-65). The median procedural time was 3 hours and 13minutes. One patient in each group developed minor complications (Clavien I and II) and there were nomajor complications.Conclusion: This study demonstrates the feasibility of antegrade and retrograde warm saline perfusion forureteral preservation during cryoablation, without compromising oncologic outcomes.

Özet

Amaç: Üreter veya pelvikaliseal sisteme yakın böbrek tümörlerinin kriyoablasyonu toplayıcı sisteme termal hasar riski taşır. Radyofrekans ablasyonu için soğuk antegrad perfüzyon tanımlanmışsa da renal kriyoablasyon için sıcak salin perfüzyonu tanımlanmamıştır. Bu çalışmanın amacı perkütan renal kriyoablasyon sırasında antegrad ve retrograd sıcak salin perfüzyonunun güvenlik ve uygulanabilirliğini belirlemekti. Gereç ve yöntemler: Tek bir akademik kurumda 2009 ile 2015 yılları arasında perkütan renal kriyobalasyonla tedavi edilmiş 136 hastada retrospektif bir inceleme yapılmıştır. Toplayıcı sistemin korunması amacıyla 3 hasta antegrad ve 3 hasta da retrograd sıcak salin perfüzyonu uygulanmıştır. Antegrad teknikte sıcak salin 4 Fr nefrostomi tübü, retrograd teknikte ise 6 Fr terminal ucu delikli kateter içinden verilmiştir. Tümörün rekürens hızı, ürotelyal dokunun korunmasındaki başarı, hastanede yatış, kan kaybı ve işlem süresine ilişkin sonuçlar elde edilmiştir. Bulgular: Dört tümör alt ve iki tümör orta poldaydı. Tümörden üretere ortalama mesafe 6,8 mm (0,8-11,5 mm) idi. Hiçbir hastada üreter darlığı gelişmedi. Ortalama 37,3 (7-65 ay) aylık takipte tümör rekürensi yoktu. Ortalama işlem süresi 3 saat 13 dakika idi. Her bir gruptan bir hastada minör komplikasyonlar gelişmişti (Clavien I ve II) ve önemli bir komplikasyon yoktu Sonuç: Bu çalışma onkolojik sonuçları riske atmaksızın kriyoablasyon sırasında üreterin korunması için antegrad ve retrograd ılık salin perfüzyonunun uygulanabilir olduğunu göstermektedir
