Duplex Systems

Vesicoureteral reflux (VUR) is the most common anomaly associated with duplex systems. In addition to an uncomplicated duplex system, reflux can also be secondary in the presence of an ectopic ureterocele with duplex systems. Controversy exists in regard to the initial and most definitive management of these anomalies when they coexist. This paper will highlight what is currently known about duplex systems and VUR, and will attempt to provide evidence supporting the various surgical approaches to an ectopic ureterocele and duplex system and the implications of concomitant VUR.

Duplex Systems

A duplex urinary tract, irrespective of the degree of duplication, is present in 0.8% at autopsy, of which about 20–35% is bilateral. The majority of duplex systems are incomplete, indicating that the ipsilateral ureters fuse before entering the bladder. A complete duplex system shows anomalies of the upper moiety, with associated ureterocele or ectopic ureter, and of the lower moiety, frequently associated with vesicoureteral reflux. Renal ectopia is a rare (1/1000) congenital defect where the kidney is not located in the renal fossa, and is associated with a high rate of hydronephrosis, vesicoureteral reflux, and abnormal contralateral kidney. In a horseshoe kidney (present in 1/400 to 1/1800), fusion of the two kidneys takes place, but the two renal moieties are still located on both sides of the midline. As the lower poles are fused in the midline, a horseshoe kidney is usually located lower than normal and orientation of the renal axis is shifted, which may guide diagnosis during abdominal ultrasound.

The gray scale ultrasound findings in two children with ectopic ureterocele are presented and correlated with traditional radiographic findings. In one case, the diagnosis was made in utero, utilizing ultrasound. The examination is noninvasive and performed quickly, and it may be able to replace the intravenous pyelogram in the initial evaluation of patients suspected of having such congenital anomalies. Retrograde cystography will still be necessary to detect vesicoureteral reflux.

Complete Duplication

ABSTRACT Duplication of the ureters is a common anomaly and is frequently encountered by radiologists. Duplication may be either complete or incomplete and is often accompanied by various complications. Incomplete duplication is most often associated with ureteroureteral reflux or ureteropelvic junction obstruction of the lower pole of the kidney. Complete duplication is most often associated with vesicoureteral reflux, ectopic ureterocele, or ectopic ureteral insertion, all of which are more common in girls than in boys. Vesicoureteral reflux affects the lower pole
