Cell-based therapy for the treatment of female stress urinary incontinence: an early cost–effectiveness analysis

Aim: To perform an early cost–effectiveness analysis of in vitro expanded myoblasts (IVM) and minced myofibers versus midurethral slings (MUS) for surgical treatment of female stress urinary incontinence. Methods: Cost–effectiveness and sensitivity analyses were performed using a decision tree comprising previously published data and expert opinions. Results & conclusion: In the base case scenario, MUS was the cost-effective strategy with a negative incremental cost–effectiveness ratio compared with IVM and a positive incremental cost–effectiveness ratio compared with minced myofibers. However, the sensitivity analysis indicates that IVM may become an alternative providing greater effect at a higher cost. With the possibility of becoming more effective, IVM treatment would be advantageous over MUS given its reduced invasiveness and lower risks of complications.
