Cross fused ectopic kidney a rare congenital malformation with review of literature

Abstract

<p class="abstract"><span lang="EN-US">Crossed renal ectopia is one of the rarest urinary system anomalies. It is more often seen at autopsy than in clinical practice. Most cases of renal ectopia remain asymptomatic during life and are diagnosed incidentally. Renal ultrasonography, intravenous pyelography, computerized tomography, and renal scintigraphy (technetium-based tests) are the imaging methods used for diagnosis. Demonstration of crossed renal ectopia is important because it is a predisposing factor for obstruction, infection, and neoplasia of the urinary system. We report male patient who had unremarkable clinical findings. He had left-to-right inferior crossed renal ectopia with fusion. Surgeons should be aware of ectopic and fused kidneys to minimize perioperative complications because of the uncertain anatomy.</span></p>

Embolization of an angiomyolipoma in a crossed fused renal ectopia

“…It represents a clinically important entity, where approximately half of patients may develop complications, such as infections (pyelonephritis), obstruction (hydronephrosis) and nephrolithiasis, but they are very rarely associated with carcinoma. 1 , 3 Despite renal AMLs are more likely to grow, most of them can be treated by active surveillance, 4 depending on tumor size and symptoms. 5 Tumors that are symptomatic or have a hemorrhagic potential require either selective embolization or surgical intervention such as partial nephrectomy, enucleation or wedge resection.…”
