An observational study of Acute Kidney Injury and Chronic Kidney Diseases, run by Centre Hospitalier William Morey - Chalon sur Saône at 1 site in France.
Trial summary
Kidney biopsy play a key role for the investigation of either acute kidney injury or chronic kidney disease. Despite possible complications due to the invasive nature of the biopsy, such procedure is still essential in a number of clinical situations to improve the diagnosis specificity of kidney disease, better… Read more about this study

About this study
Official title: Histopathological Analysis of Renal Biopsies With Dynamic Full-field Optical Coherence Tomography, a Comparison to Conventional Histopathological Findings for the Diagnosis of Either Acute Kidney Injury or Chronic Kidney Disease in Routine Practices
Kidney biopsy play a key role for the investigation of either acute kidney injury or chronic kidney disease. Despite possible complications due to the invasive nature of the biopsy, such procedure is still essential in a number of clinical situations to improve the diagnosis specificity of kidney disease, better inform about its prognosis and guide the management of a future treatment. Pursuing the idea to improve both performance and rapidity associated with the histopathological analysis of kidney biopsy, with a possible recourse to artificial intelligence-based renal pathology, the present study intends to assess the impact of direct histopathological examination of kidney biopsy with dynamic full-field optical coherence tomography in routine practices for the diagnosis of either acute kidney injury or chronic kidney disease.

What is being measured
The primary outcome is the main question the study is designed to answer.
Histopathological analysis of elementary lesions in nephropathology with dynamic full-field optical coherence tomography
Provide a better understanding of the ability of dynamic full-field optical coherence tomography to identify and characterize common glomerular (abnormal / double contour of the glomerular basement membrane, focal segmental glomerulosclerosis, collapse of the glomerular tuft, proliferation of glomerular epithelial cells, endocapillary proliferation, mesangial expansion, necrosis and proliferation with mild increase in extracapillary cells...), vascular (hyaline change, fibrinoid change / necrosis, thrombosis, inflammation or necrosis of vascular walls, arteriosclerosis) and tubulointerstitial (acute tubular necrosis, cytoplasmic vacuolization, lipid inclusions in proximal / distal tubular cells, atrophy of tubules, edema, inflammation or interstitial fibrosis, cortical necrosis) lesions seen in kidney biopsy
Measured: Outcome measure is assessed 15 days following kidney biopsy
Secondary outcomes (1)
Histopathological analysis of healthy kidney biopsy with dynamic full-field optical coherence tomography
Provide a better understanding of the ability of dynamic full-field optical coherence tomography to identify and characterize healthy glomerular (glomerular basement membrane, glomerular tuft, endothelial, epithelial, and mesangial cells, glomerular capsule and capsular space, glomerular capillaries), vascular (afferent and efferent arterioles, interlobular artery) and tubulointerstitial (proximal and distal tubular cells, normal cytoplasmic aspect) structures seen in kidney biopsy
Measured: Outcome measure is assessed 15 days following kidney biopsy

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?

What does the primary outcome measure?
Histopathological analysis of elementary lesions in nephropathology with dynamic full-field optical coherence tomography (time frame: Outcome measure is assessed 15 days following kidney biopsy). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05728216, which also lists 2 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Mar 2026; AzTrials last refreshed its copy on 7 Nov 2026.
