肾血管平滑肌脂肪瘤21例

复习报告２１例肾血管平滑肌脂肪瘤（ＡＭＬ）的临床资料。年龄３１～７０岁（平均４４．５岁）。常见症状为腰、腹疼痛、包块、血尿、发热。２例有典型结节性硬化病的征象。临床上主要依据Ｂ超和ＣＴ检查诊断肾ＡＭＬ。资料表明，Ｂ超结合ＣＴ检查使术前诊断的准确性明显提高。肾ＡＭＬ常表现为Ｂ超强回声和ＣＴ低密度影团块。本组１１例行肾切除，但７例行保肾手术，３例随访，治疗效果同样良好。由于术前能诊断，肾ＡＭＬ的治疗趋向采用保肾手术或随访观察。

Renal Angiomyolipoma: A Report of 21 Cases

A series of 21 patients, aged 31-70 years (median 44. 5), with renal angiomyolipoma (AML) was reviewed. The common symptoms of this disease were flank pain, mass, haematuria and fever. Two patients had typical sign of tuberous sclerosis. The diagnosis of renal AML depended mainly on CT scan and ultrasonography which improved the accuracy of pre-operative diagnosis markedly. 11 patients in this series were treated with nephrectomy, while 7 underwent partial nephrectomy and 3 non-surgical treatment. The therapeutic results of these three modalities of treatment were almost the same. As a result, the pre-operative diagnosis makes it possible to resort to more conservative treatment for AML.
