This is the protocol for a review and there is no abstract. The objectives are as follows: To determine whether combinations of conservative interventions for urge, stress, or mixed urinary incontinence reduce the number of people with urinary incontinence compared against no treatment/usual care, or another intervention. The secondary objectives are to determine the effect of combined conservative interventions on subjective perceptions of cure or improvement; the severity of incontinence or urinary symptoms; quality of life or symptom distress; satisfaction with treatment; cost; or adverse events. The specific comparisons to be made include: combined conservative intervention versus no active treatment (e.g. no treatment, wait list control, attention control or usual care); combined conservative intervention versus another single active treatment (e.g. a single conservative intervention, or an active non-conservative intervention); one combined conservative intervention versus another combined active conservative treatment.
