Objective: To assess the application value of selective renal arterial embolization in treating delayed renal hemorrhage occurred after percutaneous nephrolithotomy (PCNL). Methods: During the period from Feb. 2010 to July 2011, PCNL was carried out in 515 patients. Of the 515 patients, delayed renal hemorrhage occurred in 25 within 2-7 days after PCNL. Selective renal arterial embolization, including 16 right kidneys and 9 left kidneys, was performed by using PVA or Gelfoam particles and/or steel coils as embolic agents. The results were analyzed. Results: Successful embolization with single session was achieved in all 25 cases. The lesions included pseudoaneurysms (n = 12), arteriovenous fistulas (n = 7), pseudoaneurysms associated with arteriovenous fistulas (n = 4) and renal artery vasospasm at lower pole of the kidney (n = 1). The remaining one case showed normal findings on DSA. A follow-up lasting for 1-6 months was made. During the follow-up time no recurrence of hematuria was seen and no serious complications occurred. Conclusion: Selective renal arterial embolization can promptly stop the renal bleeding and effectively preserve the renal function. Therefore, this technique is of great clinical value in treating delayed renal hemorrhage occurred after PCNL.
