Kidney organ injury scaling: 2025 update.

The American Association for the Surgery of Trauma initially published the organ injury scaling for the kidney in 1989, which was subsequently updated in 2018. This current American Association for the Surgery of Trauma kidney organ injury scaling update incorporates the latest evidence in diagnosis and management of renal trauma and is based upon a multidisciplinary consensus. These changes reflect the near universal use of computed tomography for renal trauma evaluation and the widespread adoption of conservative management across all grades of renal trauma.

Intraperitoneal Bleeding After Ultrasound-Guided Transperineal Prostate Biopsy.

Transperineal prostate biopsy is becoming a popular approach in the diagnosis of prostate cancer. Urethral bleeding and urinary retention are the most common complications. We report a case of intraperitoneal bleeding after transperineal prostate biopsy in a patient with history of focal therapy for prostate cancer.

External validation of the MiGUTS nomogram for the prediction of bleeding control intervention after renal trauma.

Introduction: The American Association for the Surgery of Trauma (AAST) renal trauma grading leads to a variable management of patients with high-grade renal injuries. For a better prediction of the risk for bleeding interventions, Keihani et al. introduced the multi-institutional genito-urinary trauma study (MiGUTS) renal trauma nomogram in 2019.

Proposed revision of the American Association for Surgery of Trauma Renal Organ Injury Scale: Secondary analysis of the Multi-institutional Genitourinary Trauma Study.

Background: This study updates the American Association for the Surgery of Trauma (AAST) Organ Injury Scale (OIS) for renal trauma using evidence-based criteria for bleeding control intervention.

Methods: This was a secondary analysis of a multicenter retrospective study including patients with high-grade renal trauma from seven level 1 trauma centers from 2013 to 2018. All eligible patients were assigned new renal trauma grades based on revised criteria.

Shattered Kidney After Renal Trauma: Should It Be Classified As an American Association for the Surgery of Trauma Grade V Injury?

Objective: To study the prevalence and management of shattered kidney and to evaluate if the new description of "loss of identifiable renal anatomy" in the 2018 American Association for the Surgery of Trauma (AAST) organ injury scale (OIS) would improve the ability to predict bleeding control interventions.

Methods: We used high-grade renal trauma data from 21 Level-1 trauma centers from 2013 to 2018. Initial CT scans were reviewed to identify shattered kidneys, defined as a kidney having ≥3 parenchymal fragments displaced by blood or fluid on cross-sectional imaging.
