Behavioural therapy seems to be superior to drugs alone for Urinary Incontinence
In a new systematic review and network meta-analysis (NMA) of 84 randomized trials published in the Annals of Internal Medicine, most interventions including combination therapies improved or resolved women's symptoms better than no treatment, whether sham or watchful waiting. Hormones and periurethral bulking agents appeared less than effective, however.
Women with stress UI improved more with behavioural therapy (alone or with hormones) than with alpha-agonists or hormones alone. Alpha-agonists typically outperformed hormone therapy. Neuromodulation appeared better than no treatment for improving or resolving symptoms or increasing patient satisfaction.
Among urgency UI treatments, behavioural therapy more often led to improvement or cure than anticholinergics. Both neuromodulation and botulinum toxin A were more effective than no treatment. Onabotulinum toxin A outperformed neuromodulation for symptom resolution.
Investigators considered each intervention or combination according to whether it was first-, second-, or third-line therapy. Adverse events varied according to the intervention, and they included dry mouth, nausea, and fatigue following drug therapy.
These findings are consistent with previously published systematic reviews regarding nonsurgical treatment of UI in women but are more complete, because it was evaluated additional medication classes and interventions, and conducted NMAs to combine direct evidence from head-to-head comparisons with indirect evidence.
