Abstract

Objective: The aim of this study was to evaluate the predictor of unsuccessful outcome of renal angioembolization (RAE). Knowing those predictors may help in avoiding unnecessary RAE procedures and their associated side effects, while helping to prepare for an alternate procedure and improving patient's overall satisfaction.

Methods: A retrospective analysis between January 2006 and December 2018 was performed, and the indications for RAE were classified into post-traumatic, iatrogenic, renal tumors, and spontaneous. Patients who underwent RAE prior to nephrectomy were eliminated. Computed tomography angiography was performed in patients with normal renal function and those who had no contrast allergy, otherwise magnetic resonance angiography was performed. For the purpose of statistical analysis, we stratified patients into two main categories based on the final outcome—successful or failed.

Results: Of 180 patients, 32 with negative angiography were eliminated, leaving 148 patients; 136 (91%) had successful outcomes after one or more trials and 12 had unsuccessful outcomes. The mean age was 45±15 years, and 105 (71%) were male. Neither gender, side of the lesion, presence of hematuria, indication for RAE, nor the type of lesion affected the outcome. On the other hand, renal anatomy with presence of accessory artery was the only predictor to failed RAE (p=0.001). Failed RAE trial was a predictor for nephrectomy as a secondary procedure (p=0.03).

Conclusion: No pre-procedural predictors could anticipate the RAE outcome, and different indications can be scheduled to RAE, which is equally effective. The presence of accessory renal artery on diagnostic angiography is the only factor that may predict the failure of the procedure.

Patients’ demographics (N=148).

Bivariate analysis between different predictors and the outcome.

Left renal angioembolization in a 13-year-old male patient with recurrent attacks of hematuria after accidental renal trauma. (A) Selective left main renal artery angiography by cobra head catheter showed normal intra renal arteries with no evidence of vascular abnormalities. There was an accessory renal artery seen arising from aorta below the main renal artery (arrow). (B) Selective angiography of the accessory left renal artery showed small upper polar contrast filled cavity representing pseudoaneurysm (arrow).
