[Complications and sequelae of blunt renal trauma: the problem of terminological differentiation of concept].

General issues related to the conceptual distinction between the terms "complication" and "sequela" in renal injuries are addressed in the article. Selected principles of medical terminology from the perspective of linguistic description of the terms in question are analyzed. In addition, an analysis of synonymy among their English equivalents is presented. The need to systematize term types based on logical genus-species definitions is discussed from the standpoint of domain experts in order to enable effective expert assessment, adequate representation of scientific knowledge and viewpoints, and correct formulation of diagnoses in medical documentation.
