Hi there can male thrush cause burning when passing urine?

Yes: Thrush (candidiasis) can cause burning on urination in men by causing urethritis(inflammation or infection of the urethra). Thrush can also cause cystitis, but this mainly occurs in seriously ill patients who are immunocompramised. You need an evaluation to determine if your symptoms are to urethritis from thrush or from more likely non gonococcal urithritis or GC(both are STD's). *see comments
