Comparison of Hounsfield Unit and İntraoperative “GATA Scale” Score to Determine Requirement of DJ Stent Insertion in Ureteral Stone Treatment

Öz:
Objective: In this study, we aimed to determine the contribution of hounsfield unit (HU) measurement with non-contrast-enhanced computedtomography to the treatment of a single ureteral stone, and compare the value of HU and intraoperative “GATA scale” score in deciding for DJ stentplacement in patients with a single ureteral stone.Materials and Methods: Ninety patients diagnosed with a single ureteral stone in our clinic between January 2018 and September 2018 wereevaluated prospectively. We planned a new scale called “GATA scale” with three benchmarks. The validity and reliability of HU were compared withthose of GATA scale score. Statistical significance was defined as p<0.05.Results: The mean stone volume at diagnosis was 245.29±23.9 $mm^3$. The mean HU of ureteral stones was 1065.21±33.5. The mean total scoreaccording to GATA scale was 6.44±0.2. To determine the threshold value for factors affecting stent placement after lithotripsy, receiver operatingcharacteristic analysis was performed for stone volume, laser duration, total energy to complete laser lithotripsy and GATA scale score and showedthat the optimal thresholds were 164.01 $mm^3$, 4.25 mins, 1004 W and 7.5, respectively.Conclusion: In clinical practice, GATA scale can be used in decision making for DJ stents placement. Stent placement following lithotripsy isrecommended especially in patients with a stone volume of greater than 160 $mm^3$ or total energy to complete laser lithotripsy over 1000 W or laserduration longer than 4 minutes or GATA scale score higher than 7.

Üreter Taşı Tedavisinde DJ Stent Yerleştirme Gerekliliğini Belirlemek İçin Hounsfield Ünitesi ve İntraoperatif “GATA Skala” Puanının Karşılaştırılması

Amaç: Bu çalışmada, kontrastsız bilgisayarlı tomografi ile hounsfield ünitesi (HÜ) ölçümünün üreter taşı tedavisine katkısını belirlemeyi ve DJ yerleştirilmesi gereksinimini belirlemek için HÜ ve intraoperatif “GATA skala” puanlarının karşılaştırılmasını amaçladık. Gereç ve Yöntem: Ocak 2018 ve Eylül 2018 tarihleri arasında kliniğimizde tek bir üreter taşı tanısı konan 90 hasta prospektif olarak değerlendirildi. Üç kriter ile “GATA ölçeği” adı verilen yeni bir ölçek planladık. HÜ’nün geçerliliği ve güvenilirliği için GATA skala skoru ile karşılaştırıldı. İstatistiksel anlamlılık p<0,05 olarak tanımlandı. Bulgular: Üreteral taşı olan hastalarda tanıda ortalama taş hacmi 245,29±23,9 $mm^3$idi. Üreter taşlarının ortalama HÜ değeri 1065,21±33,5 idi. GATA ölçeğine göre ortalama toplam puan 6,44±0,2 idi. Litotripsi sonrası stent yerleşimini etkileyen faktörlerin eşik değerlerini belirlemek için taş hacmi, lazer süresi, tamamlanan lazer litotripsinin toplam enerjisi ve GATA skala skoru için alıcı işletim karakteristiği analizi yapıldı ve optimal eşik sırasıyla 164,01 $mm^3$ , 4,25 dakika, 1004 W ve 7,5 saptandı. Sonuç: Klinik pratikte, GATA skalası, DJ stentlerin yerleştirme kararında kullanılabilir. Özellikle taşın hacmi 160 $mm^3$ ’ün üzerinde veya toplam enerji 1000 W’nun üzerinde veya lazer süresi 4 dakikadan fazla veya GATA skalası 7’den fazla ise, litotripsiden sonra stent yerleştirilmesi önerilir.
