過去二十年來，因血管攝影術的普遍應用，先天性動靜脈畸型的診斷明顯的增加。近日，都卜勒超音波夾其非侵犯性及高準確度的優勢，在動靜脈畸型的診斷上，扮演重要的角色。同時在治療方面，從早先的腎臟切除術轉變成對腎臟功能傷害較少的動脈栓塞術。本篇報告，從三位因血尿而就診的女性患者，診斷出先天性動靜脈畸型。三個病灶皆由都卜勒超音波所偵測到，並以動脈攝影術作最終的診斷。患者接受經動脈栓塞術。經一年半的追蹤，再無血尿的發生，本篇報告並討論不同栓塞物質的優劣。

In the last 2 decades, diagnosis of congenital renal arteriovenous malformation has increased owing to the availability of angiography. Recently, color Doppler ultrasound has played an adjunctive role in the detection of renal A VM for its non-invasive means and efficiency. Meanwhile, the treatment of choice has changed from nephrectomy to transarterial embolization for minimizing renal parenchymal damage. In this report, congenital renal AVM leading to gross hematuria was diagnosed in 3 females. Three lesions were all detected by color Doppler ultrasound and were proved by renal angiography. Superselective transarterial embolization was performed in these 3 cases. For 1.5-yr follow-up, no more microscopic or gross hematuria was found.
