The objectives of this survey were to establish the prevalence, onset, severity and impact of incontinence and attitudes towards the availability of advice and treatment in female adults with cystic fibrosis (CF) in Northern Ireland. All female patients (n=59) at the Northern Ireland Regional Adult CF Centre were posted a questionnaire on incontinence. Leakage of urine occurred in 14/46 respondents. Leakage of urine occurred when chest was bad in 8/14 patients and when chest was good or bad in 3/14 patients. Patients reported that their bladder problem affected their ability to perform airway clearance or cough (13/14), and exercise (4/14). The main reason given for the patients who did not seek help for their incontinence (10/14) was that they were too embarrassed. This study highlights that patients with CF are reluctant to seek treatment for incontinence despite the impact this condition can have.
