Abstract：Objective: To evaluate the efficacy and safety of interventional techniques for emergent treatment of iatrogenic renal injury hemorrhage. Methods: Thirty-four patients with iatrogenic renal injury hemorrhage were treated with transarterial embolization (TAE). Fourteen had a history of renal biopsy, 8 had partial nephrectomy, 8 had percutaneous nephrolithotomy (PCNL), 3 had percutaneous nephrostomy (PNT), and 1 had percutaneous argon-helium knife. The embolic materials included metallic coils, polyvinyl alcohol particles (PVA), gelfoam and n-butyl cyanoacrylate (NBCA) iodized oil mixture. Results: Renal angiogram revealed the pseudoaneurysm in 21 cases, the arteriovenous fistula in 8 cases, and contrast media extravasation in 10 cases. The technical success was achieved in all procedures. Medical successes were achieved in 30 patients, and all patients discharged 30 days later after the embolizations. Four patients died within 10 days later after the procedures, and all of them accompanied with hemorrhagic shock and renal insufficiency. Follow-up time ranged from 5-48 months. All of the 30 patients had no re-bleeding and serious complications. Conclusions: TAE is an effective and minimally invasive treatment method for iatrogenic renal injury hemorrhage.
