Right hydronephrosis, albeit mild grade. But what could be the cause?
The right ureter was dilated (hydroureter); till its distal part where I saw this calculus of 9 mm.!
Power Doppler ultrasound imaging shows the twinkle artifact, at the site of the right ureteral (ureteric) calculus.

This lady has pain just the exact site of the stone in the dilated right ureter. This made it easy to trace the calculus.
