ABSTRACT

PURPOSE: The reproducibility of bladder filling influences the target volume position for pelvis radiotherapy. The objective of this study was to summarize the current knowledge on the use of portable echograph systems named Bladderscan (BS) in this context. MATERIAL AND METHODS: Review of the PubMed and Google Scholar publication databases was performed between September 2020 and April 2021. Results of this research were filtered in accordance to a set of eligibility criterias and are presented in this article. RESULTS: Keyword search yielded a total of 2407 publications, which filtered down to 10 relevant articles in accordance to the eligibility criterias. These publications described the viability of the BS measures as well as their clinical and organizational repercussions. CONCLUSION: According to multiple studies, BS allows to measure the bladder volume before each radiotherapy session. The use of BS decreases the amount of Cone Beam Computer Tomography potentially rejected due to non-conformed bladder filling, and improve the throughput of patients.
