Abstract

 

Renal fusion anomalies, in which both kidneys are fused togeher in early embyronic life, are rarely encountered. Once a fused kidney is diagnosed or suspected, further laboratory and imaging evaluation should be performed to assess the status of the kidneys and to look for treatable causes of renal pathology. The early dignosis of potential complications that can accompany this anomaly must be made in order to prevent permanent renal damage. The advantage of multidetector computed tomographic (MDCT) urography is its ability to depict the normal urinary tract anatomy, including both the renal parenchyma, and collecting structures and ureters. MDCT urography is helpful to screen for the presence of stones, hydronephrosis or masses. Additionally, it provides information about the vascular supply of the fused kidneys. Therefore, MDCT urography enables a comprehensive evaluation of patients with renal fusion anomalies in a single examination. Especially three-dimensional reformatted images can provide good delineation of congenital fusion anomalies of the kidney. In this study we report our experience with MDCT urography for the anatomic demonstration of renal fusion anomalies.
