Complete ureteral duplication associated with megaureter and ureteropelvic junction dilatation: report on an adult cadaver case with a brief review of the literature.
Although ureteral duplication, megaureter (MU) or ureteropelvic junction obstruction is a common anomaly of the urinary tract, complete ureteral duplication accompanied by MU and ureteropelvic junction dilatation (UPD) appears to be rare. In this paper, a case of a Japanese female cadaver with complete ureter duplication associated with MU in the upper pole ureter (UpU) and UPD in the lower pole ureter (LoU) is described. Besides describing and illustrating this case, we discuss the anatomy and etiology of these anomalous structures with a brief review of the literature.
