Renal reversed rotation is a congenital abnormality due to anomalous kidney rotation around its long axis, resulting in faced laterally renal hilum; this condition is associated with several vascular variants. The aim of this report is to describe the case of a 47-year-old male with renal reversed rotation who came to our attention after ultrasound exam. The association of renal rotation and vascular anomalies increases long-term complications as kidney lithiasis, hydronephrosis, colic pain, hematuria, and renal failure. We decided to study the anatomy and renal function of the reversed rotated kidney by multiphasic computed tomography and renal dimercaptosuccinic acid-scintigraphy. It is critical for urologists and radiologists to recognize this abnormality in order to plan the best treatment and follow-up.
