Kidney confusion

I'm sharing a couple of nice, fresh images of my daughter Haya performing two physical feats: assisted walking and floating on her back. 

This clip show Haya during a very recent hydrotherapy session:

And here she's doing her daily assisted walking;

What's confounding us is that the same week they were recorded, we received the results of her first-ever kidney ultrasound. Neither her neurologist or GP has so far responded to our request for feedback. But to our untrained minds the findings look worrying.

While her right kidney is in great shape, her left one sports the following pathologies:

• a 0.6 cm kidney stone
• several parapelvic cysts
• a compressed pelvis (אגן גדוש).

For now, we're distracted by the hectic preparations for Passover. But it would be nice to know whether any of the above requires intervention. 

Unlike our doctors, Google has been accessible and informed us that a stone of that size is deemed "large" and that those cysts, while probably not life-threatening, may or may not require treatment.

Hoping everyone has a פסח שמח! A truly joyous Passover to all who celebrate it.
