Hemorrhagic complications after ultrasound-guided percutaneous native renal biopsy: a prediction model based on clinical and ultrasonographic features under a nest case–control design
摘要
To identify independent risk factors for hemorrhagic complications after ultrasound-guided percutaneous native renal biopsy (UG-PRB) from clinical and ultrasonographic parameters, and to develop prediction models.
MethodsThe single-center retrospective study included 2822 patients who underwent a UG-PRB between May 2022 and July 2024. Patients with post-procedural hemorrhagic complications were included as the case group. Under a nest case-control design, one procedure date-matched control without complication was randomly selected for each case. Independent predictors for overall hemorrhagic complication and severe hemorrhagic complication were investigated by multivariate logistic regression.
ResultsA total of 204 patients (36.0 years ± 16.1[SD]; 104 [51%] female) developed post-biopsy hemorrhagic complications in this study. The incidence of overall and severe bleeding complications was 8.8% (204/2328) and 1.03% (24/2328), respectively. Right renal biopsy (OR 0.40, p = 0.02), number of needle passes (OR 0.40, p = 0.002), and hypertension (OR 1.29, p = 0.02) were independent risk factors for overall bleeding complications. Hyperlipidemia (OR 0.10, p = 0.04), D-dimer (OR 1.27, p = 0.03), and eGFR (OR 0.90, p = 0.002) were independent risk factors for severe hemorrhagic complications. The prediction models for overall and severe complications had AUCs of 0.64 and 0.91, and a five-cross validation in the cohort showed a mean AUC of 0.65 and 0.85 in each model. In predicting severe complications, the sensitivity and specificity were 87.5% and 75.3%, respectively.
ConclusionThe developed prediction models provide effective tools for risk stratification, early prevention, monitoring, and management for patients undergoing UG-PRB.
