L'hypoactivitĂ© du dĂ©trusor, dĂ©finie par l'existence d'une contraction dĂ©trusorienne, rĂ©duite en force ou en durĂ©e dĂ©terminant une vidange vĂ©sicale prolongĂ©e ou un dĂ©faut de vidange complĂšte dans un temps habituel [1,2], demeure un problĂšme thĂ©rapeutique imparfaitement rĂ©solu. Les diffĂ©rentes classes pharmacologiques ayant fait l'objet d'application thĂ©rapeutique dans l'hypoactivitĂ© du dĂ©trusor (HOD), agonistes cholinergiques, anticholinestĂ©rasiques et prostaglandines visent Ă renforcer les capacitĂ©s contractiles cholinodĂ©pendantes du dĂ©trusor. La mĂ©diation non adrĂ©nocholinergique du rĂ©flexe mictionnel n'a pas fait l'objet de dĂ©veloppement thĂ©rapeutique dans cette indication. Cette mise au point corrige les rĂ©sultats des travaux cliniques contrĂŽlĂ©s Ă©valuant l'intĂ©rĂȘt clinique et/ou urodynamiques des agents cholinomimĂ©tiques dans l'hypoactivitĂ© vĂ©sicale (HOV). Leur pertinence thĂ©rapeu-tique, prĂ©ventive ou curative, en monothĂ©rapie n'apparaĂźt pas Ă©tablie et l'intĂ©rĂȘt de la combinaison d'agents pharmacologiques reste Ă confirmer.Abstract: Detrusor underactivity, defined as contraction of reduced strength or duration resulting in prolonged bladder emptying or failure to achieve complete bladder emptying within a normal time frame [1,2], remains challenging for pharmacological management. Several pharmacological agents have been proposed in the treatment of this condition, all targeting the cholinergic component of detrusor contractility. These include direct and indirect cholinergic drugs, anticholinesterasic agents and prostaglandin. Non-adrenocholinergic control of the micturition reflex is given little importance in the medical treatment of detrusor underactivity. This literature review focuses on data from controlled studies evaluating its pharmacological treatment. The preventive or curative efficacy of cholinomimetic drugs has not been established, and the effectiveness of combined therapy remains to be proved.
