The aim of this work was to investigate which preparatory measures for organ movement reduction in the external radiotherapy of prostate cancer patients, in a certain period (01.01.2016 - 01.01.2017), in all published studies, on teletherapy of prostate cancer, in two databases (Science Direct, PubMed) were used. These include urinary bladder filling protocols, instructions for draining the rectum and gastrointestinal tract, and the use of endorectal balloons. In addition, the use of laxative drugs is reported, as well as diet protocols for the patients. In the databases, 262 publications were found and information on patient preparation, regarding organ movement management, was reviewed, and from these 262 studies, 23 were filtered, which dealt with preparatory measures. The conclusion from these figures is that less than 10% of the study authors consider it relevant to mention preparatory measures for organ movement reduction. The 23 publications were processed in terms of number of patients, radiation technique, irradiation region, fractionation and the selected positioning aids and were presented clearly. Using Microsoft Excel, bar charts and tables were created to show the processed results. Information on the use of bladder management was provided by 17 publications (74%), while 19 studies (82%) mentioned preparatory measures for the rectum. Two studies used drugs and five publications mention the use of nutritional protocols. Endorectal balloons were administered to the patients in eight publications. The figures in the 2016 studies did not show any changes in organ movement management compared to the ACR guideline (2017), as the cited ACR studies often (as well as the 23 studies considered) also lagged longer than 2016.
