Abstract
Background; Renal artery embolization (RAE) refers to the occlusion of the renal artery, or some of its branches, by injection of an embolic agent through an endovascular catheter, Aim and objectives; to compare various embolic agents such as metallic microcoils, microspheres (embospheres), polyvinyl alcohol (PVA), gelfoam and histoacryl in emergent indications and techniques for RAE in management of emergency renal diseases, Subjects and methods; This combined retrospective and prospective observational study was conducted at Egyptian Military Hospitals, Radiodiagnosis and Intervention departments, and Ain Shams hospitals. The study included 18 patients with clinical and radiological confirmation of symptomatic indications for urgent RAE from 2019 to 2022. The duration of the study was 3 years, Result; small sample sized and emergent cases showing mean embolization time was 12.6 minutes with no detected recanalization nor post embolic syndrome, Conclusion; Renal artery embolization has become an effective, versatile therapeutic and adjuvant tool for many urologic conditions, both acute and chronic. It can be applied successfully in improving preoperative management of renal tumors prior to nephrectomy, achieving hemostasis in cases of hemorrhage from trauma or from tumors such as angiomyolipomas, treating complications of renal transplantation and biopsies such as arteriovenous fistulas and pseudoaneurysms, improving symptoms in patients with arteriovenous malformations and certain chronic renal parenchymal diseases, and for treating renal artery aneurysms,
