OBJECTIVE: The objective is to determine the timing and indications of transcatheter angiographic embolization (TAE) for delayed @entity548 after percutaneous nephrolithotomy (PCNL). METHODS: The medical records of 144 @entity1 who underwent arteriography and TAE for delayed post-PCNL @entity548 at five university hospitals between January 2005 and December 2012 were reviewed retrospectively. RESULTS: The mean time to the onset of post-PCNL @entity548 was 10.5  days (2 - 30  days). Clinical presentation included sudden onset @entity548 in 51 @entity1 (35.4  %), intermittent @entity548 in 67 @entity1 (46. 5  %), and continuous slow @entity548 in 26 @entity1 (18.1  %). @entity1344 occurred in 32 @entity1 (22.2  %). The mean haemoglobin decrease from the first post-PCNL day to the day of TAE was 49.5  g/L (31.0 - 79.0  g/L). Renal arteriography showed @entity2849 in 69 (47.9  %) @entity1 , @entity2548 in 28 (19.4  %) @entity1 , mixed arterial and arteriovenous lesions in 17 (11.8  %) @entity1 , arterial lacerations in 23 (16.0  %) @entity1 , and negative angiographic finding in seven (4.9  %) @entity1 . TAE was successful in stopping @entity548 in all 137 @entity1 with @entity455 . There were no major complications associated with TAE. CONCLUSIONS: TAE should be the recommended treatment for delayed post-PCNL @entity548 in @entity1 with @entity1344 and/or corrected haemoglobin decrease >30  g/L following conservative management. KEY POINTS:     Delayed @entity548 after percutaneous nephrolithotomy occurs more than 24  hours postoperatively.     @entity887 is a safe and effective treatment for delayed post-PCNL @entity548 .     @entity887 can treat @entity1344 and/or corrected haemoglobin decrease >30  g/L.
