Abstract
The case histories of 494 women referred to a urodynamic clinic with the symptom of stress incontinence were studied. None had undergone previous incontinence surgery. In only 12 patients was stress incontinence the sole symptom. In the remainder, symptoms suggestive of detrusor instability were present in 417, of a voiding disorder in 261 and of an inflammatory disorder in 166. The sign of stress incontinence was present in only 168 patients and was not a reliable guide to the diagnosis of genuine stress incontinence. Urodynamic studies were necessary in 488 patients in order to obtain an accurate diagnosis.
