no
there is no reaction. the two systems wouldn't affect each other when your body goes into a flight or fight mode it releases hormones adn those hormones do many things but would have any direct affect on the urinary system.
I don't think there is because fight or flight is response action the body makes when in a dangerous situation. Stand and fight or flight RUN.
The ALARM response
The fight or flight response is triggered by the release of stress hormones like adrenaline and cortisol in response to a perceived threat or danger. This response prepares the body to either confront the threat (fight) or escape from it (flight) in order to ensure survival.
The adrenal medulla is responsible for the fight-or-flight response. It releases a hormonal cascade that results in the secretion of epinephrine and nonrepinephrine.
Walter Cannon, a harvard physiologist, first investigated the fight or flight response in 1927.
The fight-or-flight response is influenced and enhanced by the adrenal system. When an animal senses danger, on-rushing epinephrine springs them into action.
The hormone that aids in the fight or flight response is adrenalin. Adrenalin is secreted by the adrenal medulla and makes the heart beat faster.
