Figure 2: Multidetector CT urography in a 36 year-old woman with hematuria. Nephropyelographic phase axial multidetector CT urography image (A) shows an obstructed upper pole moiety which is elegantly confirmed on a coronal multidetector CT urography image (B).

Mentions: Most congenital anomalies of urinary tract can be appreciated with MDCTU (Fig. 2). Congenital anomalies of renal position, number and form are well depicted by MDCTU (1). With optimum opacification of ureters, partial and complete duplication of the collecting system can be seen on axial source images. Improved z-axis resolution are a welcome consequence of MDCTU and aid in obtaining diagnostic quality three-dimensional reconstructions, particularly in coronal plane. These factors have improved our ability to thoroughly evaluate the urinary tract for variant anatomy. 3D reconstructions can be very useful in the characterization of urinary tract anomalies such as ureteral duplication and ectopic ureter or ureteroceles (16). An advantage of MDCTU in this clinical setting is that MDCTU can depict not only opacified ureters but also unopacified ureters, which cannot be visualized on excretory urography (18). Variant anatomy can impact on the performance of urological endoscopy and surgery and also on percutaneous intervention. Detection and mapping of these anomalies is therefore important when planning these interventions and MDCTU improves our ability to accomplish this.
