Dengue hemorrhagic fever as a rare cause of bleeding following percutaneous nephrolithotomy.

Post percutaneous nephrolithotomy (PNL) bleeding is an uncommon yet serious complication and is almost always related to a surgical cause. Nevertheless, medical cause of bleeding is rarely encountered as a cause of this dangerous complication. Dengue has been rarely reported as a cause of post operative bleeding. Bleeding diathesis in dengue occurs not only due to thrombocytopenia but also due to dysfunctional surviving platelets and increased fibrinolysis. We report a patient who developed bleeding after an uneventful PNL due to dengue hemorrhagic fever. Medical causes of bleeding such as locally endemic viral hemorrhagic fevers should also be kept in mind and evaluated especially when a surgical cause of the bleed is not found or suspected in bleeding after any surgery.
