Some suggestions:

Use positions of parts that you want

res = {0.00138329, {u -> 1.88935}}

        {0.00138329, {u -> 1.88935}}

res[[1]]

        0.00138329

res[[2, 1, 2]]

       1.88935

Use positions of parts, plus replacement:

u /. res[[2]]

        1.88935

Note the use of replacement directly into an expression.

a + u^2 /. res[[2]]

3.56964\[InvisibleSpace] + a
