Józef Dietl (1804-1878) and "his" crisis: Eponyms of a political physician and the culture of remembrance in Polish and Austrian urology and medicine.

Introduction: Medical eponyms remain widely used in clinical practice despite ongoing debate about their accuracy, ethical implications, and relevance. Józef Dietl (1804-1878), an influential physician of the Polish-Austrian medical sphere, is best known in urology for the symptom complex later termed "Dietl's crisis," describing intermittent ureteropelvic junction obstruction associated with nephroptosis. The persistence of this eponym illustrates the intersection of historical memory and modern urological practice. This study analyzes the historical development, dissemination, and contemporary significance of "Dietl's crisis," and situates it within Dietl's broader scientific and public health legacy. Material and methods: A narrative historical review was performed using primary publications by Dietl, archival documents, and secondary historical sources. A non-systematic analysis of major Englishlanguage urology and pediatric urology textbooks was conducted in collaboration with the W.P. Didusch Center for Urologic History to identify references to "Dietl's crisis." Additional examination of urological case literature and ICD-10 classifications provided further evidence of the eponym's persistence. Results: The term "Dietl's crisis" appears variably but repeatedly across major urology textbooks from the late 19 Conclusions: "Dietl's crisis" remains an enduring and clinically meaningful eponym. Its continued use, free of problematic historical associations, supports the selective preservation of established eponyms as part of the cultural and scientific heritage of urology.
