Evaluating outcomes of renal angioembolization: A retrospective study

TL;DR

This study shows that renal angioembolization is a safe and effective treatment for acute kidney bleeding, with high success rates and few complications.

Contribution

The study provides outcome data on RAE in a clinical setting, supporting its use as a first-line treatment for acute renal hemorrhage.

Findings

RAE had a 98.7% technical success rate and 93.7% clinical success rate.

Post-embolization syndrome was the most common complication (26.6%).

Major complications occurred in only 1.3% of cases.

Abstract

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.
