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
