Histology Images of Kidneys Under UUO and 5/6 Nephrectomy

Histology images of kidneys stained with H&E and Masson Trichrome, collected from models of unilateral ureteral obstruction (UUO) at 3, 7, and 14 days and from 5/6 nephrectomy at 5 days. The dataset, created by Stefanny Figueroa and last updated in April 2026, is 618.4 MB in size and available under a CC-BY-4.0 license.

Use Cases

• Training image segmentation models based on histological kidney structures visible in the stains.
• Comparing tissue morphology based on the two different staining techniques (H&E and Masson Trichrome).
• Analyzing disease progression over time based on images from the 3, 7, and 14-day UUO time points.
• Developing classifiers to differentiate between UUO and 5/6 nephrectomy injury models.

Strengths

• Contains images from two distinct histological staining methods (H&E and Masson Trichrome).
• Covers multiple time points (3, 7, 14 days for UUO; 5 days for nephrectomy) for progression analysis.
• Dataset size is 618.4 MB, suggesting a substantial collection of image files.
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Row count is unknown, which may limit suitability assessment for specific ML tasks.
• Column-level documentation is absent; field semantics must be inferred after download.
• Description metadata is limited; actual data quality and annotation details require manual inspection.
