Development of a test bench for the urodynamic simulation of the lower urinary tract^.

Stress urinary incontinence restricts the quality of life of affected individuals. To restore continence and increase the quality of life in a long term, the currently applied surgical treatment methods for more severe cases are not sufficient. To support the development of a novel intraurethral artificial sphincter with the goal to replace current systems, a test bench is developed, which simulates the lower urinary tract with regards to its urodynamics. To verify the ability of the implant to maintain continence and allow undisturbed micturition, pressure and flow conditions of the lower urinary tract are reproduced, with the option to automatically conduct test cycles.Clinical relevance- The developed test bench accurately replicates the urodynamics of the lower urinary tract and therefore allows the validation of intraurethral systems.
