Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh

 

If it is a medical matter, check with a doctor to see if you can treat it first. But if it is not controlled, and medicine is not helping Islam is built to accommodate such cases in ease. Make your Wudu close to the time or prayer, then use a clean tissue and put it inside your underwear around your private area and pray and even if drops of urine fell it should be ok you can continue in your prayer.

 

Almighty Allah knows best.
