Abstract (EN): INTRODUCTION: Renal biopsy-related vascular injuries are frequent but usually unimportant. However, they can lead to dramatic situations of hemodynamic instability and even death. Transcatheter embolization is a minimally invasive technique used to treat some forms of arterial bleeding. CASE PRESENTATION: A 33-year-old woman with acute renal insufficiency requiring hemodialysis received an ultrasound-guided renal biopsy of the right kidney. She developed a perirenal hematoma (12 cm diameter) with active bleeding from the lower pole. Superselective embolization was performed with a 2.7F catheter and microcoils 0.018 inches in diameter. Her hemodynamic status was stabilized and there was no further decrease in the hematocrit level. The renal parenchyma remained well perfused except for the embolized segment. Imaging during the follow-up period showed no significant damage. The patient was discharged with a residual hematoma. CONCLUSION: Superselective embolization therapy for renal trauma provides an effective and minimally invasive means to stop active bleeding. Immediate clinical success with minimal renal parenchyma loss can be obtained. © 2009 UroToday International Journal.
