Transplant renal artery stenosis (TRAS) is a potentially treatable cause of allograft dysfunction, hypertension and graft loss. The mainstay of treatment includes angioplasty and endovascular stenting, although observation and surgery are at times indicated. We present an unusual case of TRAS secondary to mechanical compression from a patient's enlarged native polycystic kidneys. This was treated with bilateral native nephrectomy and evidence of TRAS improved both clinically and radiographically. Recognition and treatment are important in preventing irreversible complications of TRAS.
移植肾动脉狭窄（TRAS）是同种异体移植肾功能不全、高血压和移植肾丢失的一个潜在可治疗病因。治疗的主要方法包括血管成形术和血管内支架置入术，不过有时也需要观察和手术治疗。我们报告了一例罕见的TRAS病例，其继发于患者肿大的多囊性原肾的机械性压迫。该病例通过双侧原肾切除术进行治疗，TRAS的症状在临床和影像学上均有改善。认识和治疗TRAS对于预防其不可逆并发症很重要。
