Purpose: The aim of this study was to critically appraise the efficacy and complications of Therapeutic Transarterial Embolisation (TAE) in various benign and malignant renal conditions. Material and methods: The records of all patients who underwent renal embolisation procedures, at a single institution, between March 1992 and March 2004, were reviewed. The patients were identified from hospital records via the procedure coding system and the radiology department procedures book and were analysed retrospectively. Twenty-nine patients were analysed, looking at indications, clinical outcome, complications and long-term results. Results: Twenty-nine patients underwent 35 embolisation procedures during this period. Fourteen patients with benign diseases underwent 17 embolisation procedures for haematuria or intractable pain. In the haematuria group, selective embolisation was used to treat bleeding post percutaneous nephrolithotomy (PCNL) (n=4), angiomyolipoma (n=2), arteriovenous (AV) malformation (n=1), renal artery aneurysm (n=1) and renal trauma (n=2). In the renal pain group (n=3), non-selective embolisation was done. Two of these patients had recurrence of pain despite repeat embolisation and subsequently underwent nephrectomy. Fifteen patients with advanced renal malignancy, who were deemed unfit for surgery, underwent 18 embolisation procedures for symptomatic haematuria. Twelve of the 15 patients had successful outcomes with cessation of haematuria. Three patients required repeat embolisation procedures for continuing haematuria with success. There were no major embolisation-related complications. Minor complications were self-limiting and settled with conservative management. Conclusion: Renal artery embolisation is effective in managing haematuria in benign and malignant renal conditions where indicated, with minor and easily treatable adverse effects.
