The development of an iatrogenic vascular lesion, such a renal pseudoaneurysm or arteriovenous fistula, is a rare complication of partial nephrectomy. These lesions should be considered in patients presenting with an enhancing mass in the resection bed shortly following partial nephrectomy. Early timing following surgery, large relative size, and the presence of recurrent hematuria suggest the diagnosis of an iatrogenic vascular lesion. Duplex ultrasound is a useful non-invasive imaging modality for differentiating these lesions from a local tumor recurrence.
医源性血管病变的发生，如肾假性动脉瘤或动静脉瘘，是部分肾切除术罕见的并发症。对于部分肾切除术后不久在切除床出现强化肿块的患者，应考虑这些病变。手术后早期、相对较大的尺寸以及复发性血尿提示医源性血管病变的诊断。双功超声是一种有用的非侵入性成像方式，可用于区分这些病变与局部肿瘤复发。
