Reflex anuria is an uncommon cause for acute renal failure, which occurs almost always after manipulation or irritation to kidneys, ureter, bladder or other pelvic organs.
Here we describe a case of acute renal failure due to reflex anuria following acute cardiac event. This patient had background history of urolithiasis. In the absence of other pre renal, renal or post- renal causes for acute kidney injury, we believe reflex anuria is the causative entity for acute renal failure in our patient.
Acute renal failure due to reflex anuria is related to a reflex mechanism involving arteriolar vasoconstriction and urethral spasm. Patients with reflex anuria can be successfully managed with medical or surgical interventions. Our case suggests that reflex anuria should be considered as one of the differential diagnosis of acute renal failure following acute cardiac event, especially in patients with background urological problem.
反射性无尿是急性肾衰竭的一种不常见病因，几乎总是在肾脏、输尿管、膀胱或其他盆腔器官受到操作或刺激后发生。
在此，我们描述了一例急性肾衰病例，其病因是急性心脏事件后反射性无尿。该患者有尿路结石的背景病史。在没有其他急性肾前、肾性或肾后原因导致急性肾损伤的情况下，我们认为反射性无尿是导致患者急性肾衰的原因。
反射性无尿引起的急性肾衰与涉及小动脉血管收缩和尿道痉挛的反射机制有关。反射性无尿患者可以通过药物或手术干预成功治疗。我们的病例表明，反射性无尿应被视为急性心脏事件后急性肾衰竭的鉴别诊断之一，尤其是在有泌尿系统问题背景的患者中。
