Final answer:
The method of incontinence management that should be used after other approaches have failed is intermittent catheterization.
Step-by-step explanation:
The method of incontinence management that should be used only after all other approaches have failed is called intermittent catheterization. This method involves the insertion of a catheter into the bladder to drain urine at regular intervals.
Intermittent catheterization is typically recommended when other treatments, such as lifestyle changes, pelvic floor exercises, medications, or surgery, have not been successful in managing urinary incontinence.
It is important to consult with a healthcare professional to determine if intermittent catheterization is the appropriate option for managing incontinence.
