What is the ruling on congregational prayer in the mosque for someone who has a urinary catheter but it does not prevent him from moving?

It is permissible for someone with a catheter to pray as a follower, and his prayer is valid. If he leads the prayer, the majority of jurists consider his imamate valid, but it is better for someone else to lead the people in prayer. It is permissible for him to pray in the mosque as long as he does not contaminate the mosque or those around him.
