Objectives: Renal vessel anomalies are more common in renal ectopia. Multiple detector-row 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.
Key Words: Ectopic kidney, vascular supply, MDCT, MDCTA
