自发性肾出血的诊治管理

Diagnosis and Management of Spontaneous Renal Hemorrhage

摘要: 自发性肾出血是一种罕见但严重的泌尿外科急症，其特点是在无明显外伤或其他外部因素的情况下，肾脏发生出血，主要位于肾包膜下或肾周间隙。SRH可导致急性腰腹部疼痛、低血压、血红蛋白下降，严重时甚至引发失血性休克。Wunderlich综合征是SRH的典型临床表现，指因自发性肾出血引起的急性腹痛、腰痛和休克三联征。SRH的病因多种多样，常见的包括肾脏肿瘤、肾血管异常、凝血功能障碍以及炎症性疾病等。影像学检查在SRH的诊断中起关键作用，其中超声、CT和MRI可用于评估出血范围及病因。SRH的治疗策略包括保守治疗、介入栓塞以及外科手术，具体选择取决于出血量、病因及患者全身情况。本文通过系统回顾相关文献，旨在为临床医生提供全面的诊疗指导，以提高早期识别和治疗效果，改善患者预后。

Abstract: Spontaneous renal hemorrhage is a rare but severe urological emergency characterized by bleeding in the kidney, typically within the renal capsule or perirenal space, without obvious trauma or external factors. SRH can lead to acute flank or abdominal pain, hypotension, and a drop in hemoglobin levels, potentially progressing to hypovolemic shock in severe cases. Wunderlich syndrome, the classic clinical manifestation of SRH, refers to the triad of acute abdominal pain, flank pain, and shock caused by spontaneous renal hemorrhage. The etiology of SRH is diverse, with common causes including renal tumors, renal vascular abnormalities, coagulation disorders, and inflammatory diseases. Imaging plays a crucial role in diagnosing SRH, with ultrasound, CT, and MRI used to assess the extent of bleeding and identify underlying causes. Treatment strategies for SRH include conservative management, interventional embolization, and surgical intervention, with the choice of treatment depending on the volume of bleeding, the underlying cause, and the patient’s overall condition. This article provides a comprehensive review of the literature, aiming to offer clinicians diagnostic and therapeutic guidance to enhance early detection and treatment, ultimately improving patient outcomes.
