Ektopik böbrekler ve damarlarının konjenital varyasyonları

Amaç: Böbrek ektopilerinde damar anomalilerine sıklıkla rastlanılır. Multiple detector-row computerized tomography angiography MDCTA , üriner sistem ve böbrek damarlarının değerlendirilmesinde günümüzde artan bir yere sahiptir. Bu çalışmamızda amacımız ektopik böbrekteki damar varyasyonlarını MDCTA kullanarak ortaya koymaktır. Gereç ve Yöntem: Hastanemize 2009 ila 2011 arasında altı ektopik böbrek hastası araştırıldı. MDCTA, dört erişkin hastaya hipertansiyon nedeniyle, bir böbrek taşı olan erişkin hastaya nefrektomi öncesi, bir çocuk hastaya ise diafram hernisi operasyon öncesi yapıldı. Bulgular: Altı hastanın 12 böbreğinin 20 renal arteri araştırıldı. İki vakanın birinin sol böbreğinde dört, diğerinde üç renal arter saptandı. Üçü ektopik biri normal olan dört böbrekte, bir ana bir de aksesuar arter saptandı. 17 ven inferior vena cava’ya, sol böbrekten çıkan bir ven sol common iliac vene, 2 sağ böbrek veni sol renal vene dökülüyorlardı. Sonuç: Günümüzde MDCTA ektopik böbreğin damarlarını değerlendirilmesinde önem kazanmıştır.

Ectopic kidneys and congenital variations of their vasculatures

Objectives: Renal vessel anomalies are more common in renal ectopia. Multiple detectorrow computerized tomography angiography MDCTA has become increasingly important in the evaluation of the urinary system and the renal vasculature. The aim of this study is to demonstrate the variations of vascular supply of the ectopic kidneys by using MDCTA. Material and methods: Six renal ectopic kidney cases were identified among the patients admitted to our hospital between 2009 and 2011. MDCTA was planned for four adult patients due to hypertension, for one adult patient who would undergo nephrectomy due to nephrolithiasis, and for one neonatal patient who would be operated on due to diaphragmatic hernia. Results: 20 renal arteries were identified in 12 kidneys of six patients. There were four renal arteries in a left kidney and three renal arteries in another left kidneys of two cases. There were one main and one accessory arteries in four kidneys of which three were ectopic and one was normal. There were 17 veins connected to inferior vena cava, one vein of the left kidney was connected to left common iliac vein, and two veins of the right renal vein were connected to left renal vein. Conclusion: Nowadays, MDCTA has gained significance in the evaluation of ectopic kidneys’ vasculature
