Delineation of the presence and anatomy of an obstructed, nonfunctioning upper-pole duplex system often requires multiple imaging techniques. Computed tomography (CT) was used to evaluate duplex systems in five adult patients. Independent of renal function, CT allowed assessment of the presence of a duplex system determination of whether the system was obstructed, assessment of the quantity of residual parenchyma in the upper-pole system, determination of whether the ectopic ureter was intravesical or extravesical, and assessment of the retroperitoneum to look for unusual causes of upper-pole ureteral obstruction.
