Late Onset Post-Biopsy Native Kidney Arteriovenous Fistula with Aneurysm in a Renal Transplant Recipient

Although percutaneous renal biopsy is an essential tool for the diagnosis of renal lesions and parenchymal diseases, this procedure is often associated with a number of complications, of which arteriovenous fistula (AVF) is an important one. We report a case of native kidney post-biopsy AVF in a renal transplant recipient that became symptomatic 20 years later and was successfully managed with native kidney nephrectomy. Our case reveals not only an AVF but also an aneurysm that was asymptomatic for over 2 decades.
