Evaluating outcomes of renal angioembolization: A retrospective study

Acute renal hemorrhage requires rapid, nephron-sparing management and renal angioembolization (RAE) has emerged as a minimally invasive alternative to surgery, though outcome data from varied clinical settings remain limited. Therefore, it is of interest to evaluate 79 patients who underwent RAE between January 2018 and January 2023, assessing technical and clinical success, complications and renal function changes. High-grade renal trauma (45.6%) and iatrogenic injury (29.1%) were the leading indications. RAE achieved a technical success rate of 98.7% and clinical success in 93.7% of patients, with post-embolization syndrome being the most common complication (26.6%) and major complications rare (1.3%). Thus, we show that RAE is a highly effective, safe and nephron-sparing first-line treatment for acute renal hemorrhage.
