Giant pseudoaneurysm of posterior division of renal artery: A rare complication of pyelolithotomy

Giant renal artery pseudoaneurysm after pyelolithotomy is an uncommon but important disorder. A case of giant pseudoaneurysm arising from the posterior division of right renal artery following pyelolithotomy is presented. The patient presented with a flank mass six months after pyelolithotomy. CT-scan as well as selective renal angiography revealed a giant pseudoaneurysm arising from the posterior division of renal artery. Nephrectomy was necessitated as selective embolization was not possible due to its extraordinarily large size.
