Abstract:
Objective To identify various arteriographic manifestations and the curative effects of emergency embolization of renal hemorrhage after percutaneous nephrolithotomy.Methods Emergency arteriography was performed in 21 patients of renal hemor-rhage after percutaneous nephrolithotomy.Emergency embolotherapy was conducted by using different embolic agents such as gelat-in sponge,polyvinyl alcohol (PVA)particles and coils after bleeding arteries were identified.The arteriographic manifestations and the curative effects of the treatment for renal hemorrhage were retrospectively analyzed.Results Contrast extravasations were con-firmed in 21 patients,among them,4 contrast extravasations with arteriovenous fistulas(AVF)of renal artery;3 pseudoaneurysms of renal artery.The hemorrhage completely stopped after emergent embolotherapy in 21 cases.During follow-up,no rebleedings and severe complications occurred.Conclusion Emergency arterial embolization for renal hemorrhage after percutaneous nephrolithotomy is a safe and effective treatment.The key to successful treatment is to select embolization agent reasonably and embolize the bleeding arteries thoroughly and completely.
