    First case:
    post obstructive diuresis electrolytes osmotically equivalent to 1/2 NS?

    Second case:
    aquauresis after conivaptan, that has peak plasma concentration at 2 hrs after adminitration, causing decrease in electrolyte concentration.

    Thanks:
    First case:- Urine taken someone who is anuric with sterile water irrigation before foley

    Second case:- Aquaresis after conivaptan, diluting the urine to give an lower electrolyte concentration.
