Renal sonography demonstrated a duplex left collecting system (Figure 1) and dilation of the upper pole moiety terminating as a large ectopic ureterocele at the bladder base.
Bladder sonogram. The echogenicity of the urine within the bladder (A) differs from that within the ureterocele (B) and obstructed upper pole ureter (C).

The echogenicity of the trapped urine was homogeneously increased suggesting a higher concentration of debris or minerals (Figure 2).
