Can i shower with sorbact ribbon?

Hey, first of all excuse my bad english, but i need help! I have sorbact ribbon in my open sinus pilonidalis and my nurse appointment for changing it is tomorrow and it was put in yesterday.
Nurse said i need to shower it before going that appointment but didnt say can i shower it today, so if i do shower today do i need to take sorbact away or can it get wet and still be in wound?
