Hydrocele surgery 6mo ago. Testicle bigger than other. If it does NOT glow with transillumination test, is it just healing, or did hydcle return?

Hydrocele repair. After the varicocoele has been surgically removed there should be more space in your scrotum so when you put a strong light source behind your scrotum more light should come through because some obstructing material- the Varicocoele- has been removed from the scrotal sac. It doesn't glow!
