Renal Tumors Samer Makarem MD Urology Benign renal masses  Large and heterogenous group of renal lesions  15-20% of renal masses 4 cm partial/radical nephrectomy or embolization with early intervention in young females desiring pregnancy.  Selective embolization should be considered as first-line therapy in patients with acute or potentially life-threatening hemorrhage, because surgical exploration in this setting is often associated with total nephrectomy Wunderlich syndrome  Massive retroperitoneal hg occurring is 10 % of AMLs more likely in pregnancy.  Lenk’s triad :acute flank pain ,evidence of internal bleeding ,and palpable tender abdominal mass.  Grey turner sin  Cullens sign Malignant kidney tumors Gustav Simon General considerations  A thin sliced renal CT scan remains the single most important radiographic test for delineating the nature of a renal mass.  In general, any renal mass that enhances with intravenous administration of contrast material on CT >15 (HU) should be considered an RCC until proved otherwise  Magnetic resonance imaging (MRI) is the alternate standard imaging modality for the characterization of a renal mass Renal biospsy  Considered in small renal tumors
