title: Renal colic due to spontaneous perirenal haematoma secondary to antiplatelet medication: two case reports.
abstract: We present two cases of spontaneous unilateral perirenal haematoma, following the administration of antiplatelet medication. Both patients reported no history of trauma. One patient was managed conservatively whereas the second patient needed an urgent nephrectomy. A spontaneous haematoma is a rare diagnosis that is easy to be missed. It is important to have a high index of suspicion as a prompt diagnosis can improve the morbidity and mortality of patients. The causes of spontaneous perirenal haematoma are quite varied and a bleeding diathesis can only be accepted as a cause only when all other causes have been excluded.
