This piece of research is a single centre, two-way cross over, prospective study to compare the outcomes and experience of patients completing a paper bladder diary and an electronic version. This project aims to examine whether an electronic bladder diary can improve data quality compared to a paper bladder diary. Participants will attend an introduction appointment within the Urology Department at Royal Hallamshire Hospital. The participant will complete the bladder diaries at home and will then complete a questionnaire at the Royal Hallamshire Hospital.
