Introduction. The bladder diary (BD) remains the «gold standard» for the objective assessment of lower urinary tract symptoms (LUTS), despite the development of high-tech diagnostic methods. Implementing standardized BD protocols helps reduce unnecessary invasive procedures and improves the accuracy of pharmacotherapy. In the context of the digital transformation of healthcare, the transition from paper forms to mobile technologies is becoming particularly relevant.
Purpose. To evaluate the clinical significance of the BD and determine the prospects for its digitalization, including the use of specialized mobile medical applications.
Materials and methods. A systematic search for publications was conducted in PubMed/MEDLINE, Cochrane Library, Google Scholar, eLibrary.ru, and the repositories of the EAU, AUA, ICS, and RUA (2015–2025). Clinical guidelines, systematic reviews, meta-analyses, and randomized trials focusing on the diagnostic value, reliability, and electronic formats of BD management were analyzed.
Results. The BD confirms its status as the «gold standard» for the objectification of LUTS. A three-day protocol provides the optimal combination of diagnostic accuracy and compliance. Paper diaries are associated with the risk of retrospective completion and laborintensive processing. Electronic forms increase data reliability, automate calculations, reduce the physician's time, and improve patient adherence. A practical example of digital implementation is the specialized mobile application «Etta Bladder Diary», which provides real-time event registration, automatic calculation of clinical parameters, report generation, and integration with portable home uroflowmetry. This increases monitoring objectivity and expands the possibilities for remote observation.
Conclusion. A standardized three-day bladder diary should be considered an essential stage in the diagnosis of voiding disorders. Digital solutions and mobile technologies enhance the clinical, organizational, and economic efficiency of urological care and form the basis for the development of «digital urodynamics» and patient telemonitoring.
