The role of urodynamics in female urinary stress incontinence.

The cystometrograms of 61 patients with a history of stress incontinence and no other urinary symptoms were evaluated. Of the sixty-one patients, seven had unstable bladders and in seven of the patients stress incontinence could not be demonstrated. It was concluded that all patients with stress incontinence in whom surgery is being contemplated should be subjected to urodynamic study regardless of their history.
