To explore the causes and countermeasure in recurrent bleeding following the selective renal artery embolization treating post-percutaneous nephrolithotomy hemorrhage. A total of 334 patients of severe renal hemorrhage associated with percutaneous nephrolithotomy (PCNL) from March 2011 to April 2015 were analyzed retrospectively.All the patients underwent super selective angiography and renal artery embolization.The causes of recurrent hemorrhage were analyzed and principles for diagnosis and embolization were studied. The initial embolization was performed in 329 cases hospitalized in the First Affiliated Hospital of Guangzhou Medical University and 318 cases were successfully stopped bleeding with a hemostatic rate of 96.7 %(318/329). Of total 334 consecutive cases, there were 16 cases of recurrent renal hemorrhage, 11 cases were initially embolized in this hospital, and otherwise the other 5 cases were in other hospitals. Causes of recurrent hemorrhage were missed embolization of tiny pseudoaneurysm ( =12)
