Sponsor's own description
Questionnaires are used within urology to objectify disease burden and symptom changes during therapy. Recent technological improvements, as the smartphone and tablet, create new fill-out possibilities. However, questionnaires are only validated on paper. In order to use questionnaires for multiple platforms, electronic validation is needed. The International Prostate Symptom Score has already been validated on the smartphone. The International Index of Erectile Function (normal version of 15 questions and short version of 5 questions) is widely used within urology, however electronic validation is required for usage on electronic platforms in the future.
