In the above mentioned case you should use tissue paper or clay clod after urination. And if you give some movement to your body then the rest urination shall be released quickly. When you are satisfied that the drops have stopped then wash it with water and pay no attention towards doubts. Also do not see it and do not touch it until it is not known clearly that you have released urine drops your wudhu shall not break.
Allah knows Best!
