This is when a few drops of urine leak after you've been to the toilet, even if you've 'waited and shaken'. There are two types of after dribble men experience, post-micturition dribble and terminal dribble. After dribble happens because the bladder doesn't empty completely while you urinate. Instead, the urine accumulates in the tube leading from your bladder. A common cause for after dribble is an enlarged prostate or weakened pelvic floor muscles.
