lthough the optimal initial approach to incontinence is unclear for patients of any age, nowhere is there more uncertainty than for the A elderly patient. Only recently has incontinence in this age group been recognized as an abnormality worthy of attention and as a pathologic condition with a differential diagnosis and hope for improvement.As a result, neither a validated approach nor a consensus exists regarding the extent of the initial evaluation or the type of patient who should undergo more detailed testing. The answers to these issues will ultimately require simpler diagnostic approaches and a better understanding of the pathophysiology of incontinence, its response to treatment, and the characteristics of patients most likely to respond. Until such answers emerge, however, an interim solution is necessary. But to devise such an approach, one must first review the causes of incontinence, assess the accuracy of the clinical evaluation, and weigh the consequences of misdiagnosis.
CAUSES OF INCONTINENCEContinence status is affected not only by lower urinary tract function, but also by environmental demands, mentation, mobility, manual dexterity, motivation, medications, and medical conditions. For incontinent younger individuals, factors outside the lower urinary tract rarely play a major role. But due to age-related and age-associated changes, these factors assume much greater importance in the elderly.Although there is still a dearth of data regarding the effect of age on lower urinary tract function-and no longitudinal studiesseveral points emerge from
