Percutaneous nephrolithotomy is a minimal invasive important technique for stones of the renal pelvis. However, severe hemorrhage after percutaneous nephrolithotomy is a rare but life-threatening event. Bilateral double renal arteries are kind of relatively infrequent renal vascular variation. Here, we reported a rare case of percutaneous nephrolithotomy induced renal hemorrhage in a patient with bilateral double renal arteries, and our experience of successful rescue in this patient.

Focal nodular hyperplasia (FNH) is a common benign hepatic tumor which is often treated nonoperatively until it appears apparent symptoms such as pain and upper abdominal distension. We report here a case of trans-catheter arterial embolization (TAE) using pingyangmycin-lipiodol emulsion (PLE) for blocking a fatal bleeding originated from percutaneous biopsy as well as for FNH treatment. After embolization by means of the mixture of PLE and particles of gelfoam, the bleeding was stopped and the FNH was apparently shrinked 1 year later. TAE using PLE may be considered as a safe and effective method for the treatment of FNH.
