Renal ablation in patients with end-stage renal disease

Transarterial catheter embolization of the kidneys (TAE) is a minimally invasive, image-guided procedure. In this study outcome and TAE-related complications of the patients who underwent TAE of the kidneys were evaluated retrospectively.

Between August 2003 and August 2009, 11 patients underwent selective percutaneous transarterial renal embolization for end stage renal disease associated with uncontrolled hypertension, nephrotic syndrome, bleeding or malignancy. TAE of renal arteries was performed using different embolization agents.

Successful renal embolization was possible in all 21 kidneys. All patients became anuric. Non-target embolization was not detectable. Nevertheless, all patients developed some degree of postembolization symptoms including nausea, vomiting, fever or pain. A typical finding after embolization was an increase in the C-reactive protein.

Renal embolization is rarely done but should be considered as an alternative to surgical nephrectomy in patients with end stage renal disease due to the lesser invasiveness. Our study confirms the safety and effectivity of percutaneous renal embolization in patients with ESRD. We were able to control the hypertension, nephrotic syndrome, and bleeding caused by ESRD.
