Caffeine is a cardiac stimulant and also as a mild diuretic. Both actions: an active stimulant and MILD diuretic have increased effects on urine. First the stimulant effect speads the body up and second the diuretic releases more urine...due to the fact the heart and brain controls the kidneys. Caffeine increases heartbeat, respiration, basal metabolic rate, and the production of stomach acid and urine; and it relaxes smooth muscles, notably the bronchial muscle. These symptoms start anywhere from fifteen to forty five minutes after caffeine is consumed, except the central nervous system which is hit between thirty and sixty minutes after ingestion.

Coffee is a diuretic, it increases fluid secretion in your renal cavity leading to dehydration. This is why your urine excretion increases when coffee is consumed.
