Renal dysplasia secondary to posterior urethral valves Renal dysplasia secondary to posterior urethral valves. A: Coronal image of 23-week fetus with posterior urethral valves demonstrating dysplasia of both kidneys with thin echogenic parenchyma (arrows) and marked dilation (*). Part of the dilated ureter (arrowhead) can be seen on one side. B: Coronal magnified image of one kidney showing marked dilation* and cortical thinning with increased echogenicity (arrow). C: Transverse image of a different fetus with posterior urethral valves, this one at 32 weeks, demonstrating multicystic dysplasia of both kidneys (arrows) secondary to lower urinary tract obstruction.
