Bladder symptoms often do not correlate with the underlying diagnosis. Thus urge incontinence often but not always results from an overactive bladder. Emphasis must be placed on the management of urinary incontinence in primary care, as this is effective in both the short term and the long term and benefits secondary care by ensuring that only patients who cannot be managed in primary care are referred. 6 7 Urodynamic studies can be reserved for when conservative treatment has failed, surgery is intended, there are voiding difficulties, or a neuropathy is present. #### Summary points Urinary incontinence affects 20% of women over the age of 40 It affects the quality of life and causes a financial burden to the NHS Emphasis must be placed on primary health care as many patients can be managed at this level, thus ensuring appropriate referral to hospital The main causes of urinary incontinence are urethral sphincter incompetence and an overactive bladder Urodynamic studies are reserved for when conservative treatment has failed, surgery is intended, or voiding …
