What hormone name means against urine flow?

The hormone that has the name "against urine flow" is antidiuretic hormone (ADH). ADH is a hormone that helps the body regulate water balance by reducing urine output. It is produced by the hypothalamus and released by the pituitary gland. ADH works by increasing the reabsorption of water from the kidneys back into the bloodstream. This reduces the amount of urine that is produced and helps to maintain the body's water balance.
