Embolization of a Segmental Renal Artery Pseudoaneurysm after Partial Nephrectomy in a Solitary Kidney

Abstract

Renal pseudoaneurysms are a well-documented complication following trauma or after percutaneous biopsy. When symptomatic, patients present with hematuria and deteriorating renal function. We present the case of a 62-year-old man who, due to development of a pseudoaneurysm, presented with gross hematuria 10 days after partial nephrectomy for a renal cell carcinoma in a single kidney. A segmental artery was embolized with stainless steel coils without significant loss of the limited renal vascularization.
