Provided is a urination control device which can ensure autonomous urination by adjusting the intravesical pressure by the abdominal pressure when urination is started, can prevent urinary incontinence, can design the intravesical pressure variously at the time of opening or blocking, can attain stability and high precision, can ensure control of urination by reliable blocking and opening, can prevent infection and contamination by a simple structure and safe constitutive materials, can be installed in both male and female patients, and can enhance the QOL of the patient. A urination control device comprises a conduit which is inserted into the urethra, an upstream restraint member provided on the upstream side in the conduit and having a through hole, a control member provided on the downstream side of the upstream restraint member in the conduit, and a downstream restraint member provided on the downstream side of the control member in the conduit, wherein the upstream restraint member and the control member are provided in a manner to attract each other by magnetic force, the control member abuts on the opening of the through hole in the upstream restraint member by magnetic force and blocks liquid conduction of the upstream restraint member at least in a state where the hydraulic pressure is not applied to the upstream side, and the downstream restraint member is constituted so that the liquid can be conducted in a state where the control member is latched.Linvention porte sur un dispositif de régulation de miction qui peut assurer une miction autonome en ajustant la pression intravésicale par la pression abdominale quand la miction a démarré, prévenir lincontinence urinaire, définir la pression intravésicale de manière variée au moment de louverture ou du blocage, atteindre une stabilité et une précision élevée, assurer la régulation de la miction par un blocage et une ouverture fiables, prévenir une infection et une contamination par une structure simple et de
