Abstract: A urinary control system for controlling urination has a first light source configured to selectively apply a first light and a second light to a bladder muscle and a second light source configured to selectively apply the first light and the second light to the urethral sphincter. A first optogene is expressed to the bladder muscle and the urethral sphincter, and a second optogene is expressed to the bladder muscle and the urethral sphincter, the first optogene contracts muscles by depolarizing membrane potential when the first light is applied, the second optogene relaxes muscles by depolarizing membrane potential when the second light is applied, and the contraction and relaxation of the bladder muscle and the urethral sphincter are achieved counteractively via photostimulation by the first light and the second light, respectively, so as to control urination.
