Instrumental methods for assessing the functional ability of the kidneys

Introduction. Chronic kidney disease (CKD) is a global medical problem. The long-term latent course of the disease leads to a progressive increase in its incidence. Along with laboratory methods of research in the arsenal of the diagnostic service, there are tools that allow you to detect a violation of the kidneys functional ability. Purpose. To analyze modern instrumental methods for diagnosing the functional ability of the kidneys. Materials and methods. The review was conducted based on data published in PubMed databases (https://www.ncbi.nlm.nih.gov/pubmed /) and eLibrary.ru (https://elibrary.ru) and was limited only to articles in scientific peer-reviewed journals. It was carried out until January 2023, by keywords: kidney ultrasound, computed tomography, positron emission tomography, magnetic resonance imaging, kidney function. Results. We found 189 sources not older than 10 years (published after 2012) that were relevant to the topic of the review. Conference abstracts, short messages, duplicate publications were excluded from them. After that, based on the relevance of the data, reliability of sources, impact factors of journals and the sequence of presentation of the material in the manuscript, 46 articles were selected directly for citation in the review. Also, when writing the review, original articles published before 2012 were used. Conclusion. The available modern instrumental methods for assessing renal function open up broad prospects for their clinical application and require further research.
