A Reminder App to Optimize Bladder Filling in Patients with Prostate Cancer Receiving HYPO-fractionated Radiotherapy

The primary goal of this study is to assess the impact of an app that reminds patients treated with hypofractionated radiotherapy (HF-RT) for prostate cancer to drink water prior to each radiotherapy session on the number of bladder volumes \<200 ml during the HF-RT course and to demonstrate that this number is lower than without using an app (historical control group).
