Addressing the Challenges of Urine Sediment Analysis
Manual urine sediment analysis is a cornerstone of clinical diagnostics, yet it remains labor-intensive, subjective, and operator-dependent. This leads to variability and a pressing need for accurate, efficient automation. Our multi-head YOLOv12 model, with self-supervised pretraining, directly addresses these challenges by enabling comprehensive detection and classification of 39 distinct urinary particle categories, overcoming limitations of prior single-head models and small datasets.
Innovative Multi-Head Architecture & Training
Our proposed method leverages a novel two-stage deep learning approach. First, self-supervised pretraining on a large unlabeled dataset allows the model to learn intrinsic microscopic texture and morphology priors. Second, the pretrained encoder (YOLOv12 backbone) is fine-tuned with a multi-head detection module. This module features six specialized heads (Cells, Casts, Crystals, Microorganisms/Yeast, Artifact, Others) that operate in parallel to ensure comprehensive and precise detection across the full spectrum of urinary sediment particles. Advanced inference with Slicing Aided Hyper Inference (SAHI) further enhances detection of small, densely packed structures by processing images in overlapping tiles.
The OpenUrine Dataset: A New Standard for Training
To facilitate robust training and address data scarcity, we created OpenUrine, a large-scale and diverse dataset. It includes 790 expert-labeled images with over 31,285 bounding boxes across 39 distinct categories, alongside 5,640 unlabeled images for self-supervised learning. This dataset is the first publicly available resource dedicated to urinary particle detection with such breadth, capturing real-world imaging variability.
Benchmarking Superior Detection Performance
Evaluated on this complex 39-class OpenUrine dataset, our model achieved a precision of 76.59% and a mean Average Precision (mAP) of 64.15%, demonstrating competitive performance. Notably, the multi-head design significantly improved accuracy across diverse particle types, especially for small and low-contrast objects, outperforming state-of-the-art single-head methods and previous YOLO versions.
Validating Clinical Utility and Interpretability
Clinical validation against 84 patient samples confirmed the model's high utility, achieving a mean accuracy of 86.55% when compared to laboratory technologist reports for major urinary components. The proposed method demonstrated high accuracy for critical elements like RBCs (87.31%), WBCs (88.40%), Epithelial cells (97.10%), and Calcium oxalate (93.79%). Visual explanation techniques (Grad-CAM) confirmed that the model focuses on relevant morphological structures, increasing confidence in its diagnostic decisions.

Enhanced Diagnostic Confidence & Accuracy
The integration of multi-head detection and self-supervised pretraining leads to exceptional performance in identifying a wide range of urinary particles. This translates directly to enhanced diagnostic confidence for clinicians, reducing manual review time and improving patient outcomes. For example, high accuracy for Epithelial cells (97.10%) and Calcium oxalate (93.79%) indicates robust detection of both common and clinically significant elements. The model's interpretability, verified through Grad-CAM, ensures that its decisions are based on medically relevant features.
