For the purpose of the study, the data will be stored in a central database held by ESFFU under the umbrella of EAU RF. The investigator or a qualified employee will enter all relevant patient data into a web based electronic Data Capture system. Data checks, programmed in the data capture system, use predefined rules for range or consistency with other data fields in the registry. Data will also be checked for accuracy and correctness by data-managers of the EAU RF according to internal procedures. The site will be capable of modifying the data to assure accuracy with source documentation. At the end of the study, EAU RF will archive the study data in accordance with internal procedures. Specific instructions for use of the eCRF system will be included in the training material provided to the investigational site.
