Which term refers to the distention of the ureter with urine that cannot flow because the ureter is blocked?

Explanation:
When urine cannot flow because the ureter is blocked, urine backs up and stretches the ureter. This dilation filled with urine is called hydroureter. The prefix hydro- signals urine, and -ureter specifies the affected tube, so hydroureter directly describes dilation of the ureter due to obstruction. Ureterectasis also means dilation of the ureter, but hydroureter emphasizes urine-filled dilation from blocked flow. Ureterolithiasis refers to stones in the ureter, not the dilation itself, and cystolith is a bladder stone.
