Abstract

Objective: The aim of this study was to evaluate calyceal pressure caused by irrigation of the upper, mid and lower calyces in a cadaver kidneymodel and to examine the interactions.Materials and Methods: The kidney was dissected together with the ureter from a human cadaver from a 75-year-old without a history of renaldisease. Catheters were placed in the bases of the calyces to perform pressure measurements. After recording baseline pressures while the flexibleureteroscope working channel was empty during irrigation, pressures were then measured by administering fluid with a hand pump, 5 cc and 50cc syringe. Then, 272 µ and 350 µ laser probes were placed in the flexible ureteroscope and, after recording the baseline calyceal pressures, themeasurements were repeated 3 times during hand pump irrigation.Results: Lowest calyceal pressures were measured when a 300 µ laser probe in the working channel of the flexible ureteroscope was placed in theupper calyx during irrigation at 60 cm H2O. Independent of the location of the flexible ureteroscope, the pressure in all the calyces was observedto be ≥50 mmHg during all types of fluid irrigation. All the calyceal pressures were observed to be affected by each other. The pressure within thecalyx where the flexible ureteroscope was located was statistically significantly higher than in the other calyces (p

Özet

Amaç: Çalışmamızda kadavra böbrek modelinde üst, orta ve alt kalikste farklı irrigasyon uygulamaları ile oluşan kaliksiyel basınçları ve birbirleri ile etkileşimlerini değerlendirmeyi amaçladık. Gereç ve Yöntem: Yetmiş beş yaşında bilinen böbrek hastalığı öyküsü olmayan insan kadavra böbreği üreteri ile birlikte diseke edildi. Kateter uçları kaliks tabanına gelecek şekilde yerleştirildi. Flexible ureteroskop çalışma kanalı boş iken bazal basınçlar kayıt edildikten sonra pump, 5 cc ve 50 cc enjektör ile sıvı verilerek basınçlar ölçüldü. Daha sonra flexible ureteroskopun içinden 272 ve 350 µ lazer probu yerleştirilerek bazal ve pump yapılarak 3 kez aynı işlemler tekrarlandı. Bulgular: Tüm kalikslerin basınçları en düşük 60 cm H20 irrigasyon sırasında flexible urs üst kalikste çalışma kanalı 300 µ lazer var iken ölçüldü. Flexible URS lokalizasyonundan bağımsız olarak uygulanan her türlü sıvı irrigasyonunda tüm kalikslerde basıncın 50 mmHg ve üzerine çıktığı izlendi.Tüm kaliks basınçlarının birbirinden etkilendiği gözlendi. Flexible URS’nin bulunduğu kaliks içinde basınçlar diğerlerinden daha yüksek ölçüldü ve bu istatistiksel olarak anlamlı idi (p
