Background: To assess the outcomes of patients undergoing percutaneous renal artery embolization (PRAE) prior to radical nephrectomy.
Methods: We performed retrospective chart review of patients undergoing PRAE in Auckland Public Hospital from January 2004 to December 2011. PRAE was performed under epidural anaesthesia and within 24 h of nephrectomy. We compared our perioperative outcomes with the published literature.
Results: Forty-two patients were identified in this series. Patients had predominantly more advanced stage disease with 30 (71%) being T3 or higher (TNM staging). Median operation time was 192 min (range 84-428). 45.2% of patients experienced complications from the surgery. There were no complications associated with PRAE.
Conclusions: PRAE prior to nephrectomy is a safe procedure. There is no convincing evidence in the literature that the benefits outweigh the risks. All published studies are non-randomized and subject to selection bias, so the true role of PRAE has not yet been determined and routine use is probably not justified.
