Washing off impurity

I have a problem with my bladder (over-active bladder) where I find it difficult to control it so at times I have wet myself and it has gone on the
carpet (a few drops) and with impure hands I have accidentally touched a door handle or wall. Now if I touch the same part with pure hands will my hands become impure or stand on the carpet with wet feet will it make my feet impure? Also I have a problem with a fluid that sometimes comes out of my private part. I always wash it but sometimes I don't realise it has come out until I dry myself after a shower but I have with the same hands touched the carpet or door handle or wall and put the towel on the floor, now if I touch the same part again will it make my hand or feet impure?
