Urine problem

Q: I leak pre seminal liquid very often. I was told I am a mazoor and just to make fresh wudu for every fardh salaah. My question is I also leak urine quite a few times. Does the same rule of mazoor apply? Or should I take precaution and repeat that salaah? What if that salaah time has gone?

Tabarruk
