A member asked:

Is there a connection between kidney stones and hydronephrosis!?

4 doctors weighed in across 2 answers

Yes: Kidney stones that block the draining tubular structures inside the kidney or block the ureter cause hydronephrosis.

Yes primary & 2ndary: 1) stone blocking kidney pelvis (urinary funnel) or ureter can cause kidney to swell from effects of back pressure. Hydronephrosis thus 2ndary. 2) congenital or primary hydronephrosis causes urinary stasis (like stagnation) giving dissolved calcium & other salts a chance to precipitate and develop into kidney stones. Also is easier for infection stones to develop. Stone formation is secondary.
