Waiting for a little while after istinja

I have a weak bladder due to which I cannot hold urine. After doing istinjaa I know if I will wash my private part and during washing if I try to hold my bladder, urine will come out because it cannot hold my urine which come's out due to pressure put by me trying to hold my bladder. Am I still considered mazoor? Can I still make wudhu when I know that urine drops which come out is because I have tried to hold my bladder during washing my private part? I mean before washing my private part I know if I hold my bladder, urine will come out due to it's weakness and I still make wudhu. Will my wudhu be valid? I know your ruling regarding mazoor and sorry for asking a confusing question.
