What should a person do who frequently experiences a discharge of white or yellow drops, which sometimes causes embarrassment and leads to missing prayers?

If someone experiences drops of urine after urinating, they must guard against the spread of impurity to their clothes. They should wait until the drops cease, then perform ablution (wudu') and pray, even if they miss the congregational prayer (jama'ah). This is because praying with certain purity takes precedence over congregational prayer. If one doubts whether anything has exited, they should not pay attention to the doubt until they are certain that urine has exited.
