Before Wudhu and Salah check whether you discharged or not, you could easily determine this by placing a cloth or pad in your underwear. If the discharge is transparent or white then your Wudhu is intact otherwise if its discoloured then you will need to Wudhu.

If Wudhu facility is not available then as long as there’s water you can do Wudhu and perform Salah.
And Allah knows best
