Evaluating outcomes of renal angioembolization: A retrospective study

Area of Science:

• Interventional Radiology
• Nephrology
• Urology

Background:

• Acute renal hemorrhage necessitates prompt, nephron-sparing interventions.
• Renal angioembolization (RAE) offers a minimally invasive alternative to surgical management.
• Limited outcome data exist for RAE across diverse clinical settings.

Purpose of the Study:

• To evaluate the efficacy and safety of RAE in managing acute renal hemorrhage.
• To assess technical and clinical success rates, complication profiles, and renal function changes following RAE.
• To analyze RAE outcomes in a cohort of 79 patients treated between January 2018 and January 2023.

Main Methods:

• Retrospective analysis of 79 patients undergoing RAE for acute renal hemorrhage.
• Assessment of indications, technical success, clinical success, complications, and renal function.
• Data collected from January 2018 to January 2023.

Main Results:

• High-grade renal trauma (45.6%) and iatrogenic injury (29.1%) were primary indications for RAE.
• RAE demonstrated a technical success rate of 98.7% and clinical success in 93.7% of patients.
• Post-embolization syndrome occurred in 26.6%, with major complications in only 1.3% of cases.

Conclusions:

• Renal angioembolization is a highly effective and safe first-line treatment for acute renal hemorrhage.
• RAE preserves nephrons, offering a valuable minimally invasive option for renal trauma and iatrogenic injuries.
• The procedure is associated with a low rate of significant complications and good functional outcomes.
