Renal ultrasound and voiding cystoureterography of case A. Sonography of the right (A) and left (B) kidney revealed hypoplasia and hyperechogenicity of bilateral kidneys. The right kidney measured 4.6 cm in length and left kidney 4.9 cm. A cyst was found in the left kidney. Voiding cystoureterography (C) revealed bilateral vesicoureteral reflux (right side grade II, left side grade III).

Renal sonography and magnetic resonance imaging (MRI) revealed bilateral atrophic kidneys with parenchymal disease and one left renal cyst (Figures 1A,B). Voiding cystoureterography revealed bilateral VUR, grades II and III at the right and left side, respectively (Figure 1C).

Renal ultrasound, MRI, and antegrade pyelography of case B. Ultrasonography of the urinary systems depicts small size of the right kidney with dysplasia and multiple cysts formation (A), right hydronephrosis (B), right hydroureter (C), and left ectopic kidney with dysplasia and hypoplasia. (D) MRI of the abdomen (E) confirmed the ectopic left kidney anterior to the aortic bifurcation (arrowhead). Antegrade pyelography (F) depicts high grade obstruction at the distal third of the right ureter with contrast medium not passing into the urinary bladder.

Renal sonography revealed right dysplastic kidney (Figure 2A) with moderate hydronephrosis (Figure 2B), hydroureter (Figure 2C), and left ectopic hypodysplastic kidney (Figure 2D). Abdominal MRI revealed right-side multicystic dysplastic kidney and left side dysplastic kidney with ectopia anterior to aortic bifurcation (arrowhead in Figure 2E). Antegrade pyelography revealed high grade obstruction at right distal third portion of the ureter (Figure 2F).
