RENAL ARTERY ANGIOEMBOLIZATION PROCEDURE - A SINGLE CENTRE EXPERIENCE

Abstract

Renal hemorrhage following urological procedures, due to Arteriovenous malformations or renal tumors is a critical complication that can lead to significant morbidity. While surgical exploration was once the standard, it often resulted in nephrectomy. Today, renal artery angioembolization offers a minimally invasive and highly effective alternative, preserving renal function. This case series presents four instances of uncontrolled hematuria following percutaneous nephrolithotomy (PCNL), Arteriovenous malformation and Angiomyolipoma that were successfully managed with superselective angioembolization. The cases include the formation of a pseudoaneurysm and an arteriovenous fistula post PCNL, treated with coil and iodized oil embolization, respectively. These cases highlight the efficacy and safety of angioembolization as a first-line treatment for managing hemorrhagic complications in urological emergencies, thereby avoiding more invasive surgical interventions and preserving renal parenchyma.
