Sponsor's own description

The TUCSON study is a cross-sectional observational monocentric study. In order to provide a clinical helpful assessment for urologists for possible missed causes of nocturia, the aim is to investigate the voiding and sleep pattern through questionnaires and sleep and voiding diaries of patients consulting the urology department, sleep clinic and pneumology department. An assessment of the prevalence of missed underlying causes will be made and a subset of patients will be asked to deliver urine samples from every night time and first morning void to further investigate possible differences in urine content between the groups. First of all, with this research the aim to offer an idea about the order of magnitude for missed underlying causes of nocturia. Secondly, to discover a specific sleep and voiding pattern for the different entities of nocturia and thirdly, to offer a useful screening tool for underlying pathology in clinical practice.
