Model Innovation
This study pioneers a new diagnostic model derived from enhanced CT data, focusing on renal cortex volume (RCV), venous phase renal medulla CT values (VP-HuRM), and the presence of hydronephrosis. These parameters were identified as independent risk factors for split renal function impairment, forming the basis of a logistic regression model. The model aims to overcome limitations of traditional methods like renal dynamic imaging, which involve lengthy procedures and radiation exposure.
Advanced Methodology
A retrospective analysis of 382 kidney datasets from 191 patients with obstructive hydronephrosis was conducted. Data was split into training (n=260 kidneys) and validation (n=122 kidneys) sets. Various CT parameters, including renal cortical and parenchymal thickness, CT values across phases, and derived enhancement metrics, were measured. Statistical methods included logistic regression, ROC curve analysis, and Kruskal-Wallis H tests to identify significant risk factors and evaluate model performance across different renal dysfunction severities (non-renal, mild, severe).
Clinical Impact
The developed model demonstrated high diagnostic accuracy with AUC values of 0.896 (training) and 0.928 (validation) for identifying renal function impairment. It also effectively distinguished between different grades of dysfunction (mild vs. non-renal, severe vs. mild). This non-invasive, radiation-free approach offers a valuable tool for early detection and dynamic monitoring of split renal function in obstructive hydronephrosis patients, aiding in more precise clinical decision-making and surgical planning.

Enhanced CT for Obstructive Hydronephrosis Management
A 45-year-old patient presents with symptoms of obstructive hydronephrosis. Instead of a traditional renal dynamic imaging scan, the new enhanced CT diagnostic model is applied. By quantifying renal cortex volume (RCV), venous phase renal medulla CT values (VP-HuRM), and assessing the degree of hydronephrosis, the model accurately predicts the split renal function impairment with a high AUC of 0.928. This rapid, non-invasive assessment allows clinicians to precisely determine the affected kidney's function, guiding surgical planning (e.g., nephrectomy vs. pyeloplasty) and optimizing patient outcomes without additional radiation exposure or lengthy procedures.
