Wa `alaykum As-Salamu wa Rahmatullahi wa Barakatuh

In answering this question, I would like to cite her one of my earlier answers:

“The Prophet, peace be upon him, said, ‘ if during of the course of prayer one doubts whether his/her wudu is broken or not, he/she need not leave the place (to renew wudu) unless he/she senses some foul smell (of passing gas) or hears the sound (of farting).”

Likewise, if you are in doubt about discharge of urine, you need not leave the prayer unless you feel the wetness. If after the completion of prayer, you felt the wetness in your underwear or body, then you ought to renew your wudhu and repeat your prayer.

However, if you are suffering from incontinence (inability to control your bladder/bowel) then you certainly fall in the category of those who are allowed special dispensations because of your specific condition.

In this case, what is required of you is to wash yourself and perform your wudu as closely as possible to the prayer you are about to perform. Once you have done so you need not worry about what happens after. Your prayer is considered as perfectly valid because of your specific health condition. For Allah says, “Allah does not wish to impose on any soul such burdens that it has no strength to bear.” (Al-Baqarah 2: 285)”

I pray to Allah to help you overcome this condition.

Almighty Allah knows best.
