【摘要】：目的探讨36例泌尿系结核高分辨率计算机体层摄影术(high resolution computed tomography,HRCT)表现特点以及影像学在指导治疗中的价值,以期提高诊断符合率和为规范治疗提供依据。方法回顾性分析36例经病理及临床证实的泌尿系结核患者的病例资料,研究HRCT在泌尿系结核中的扫描技术、CT平扫及增强的影像学表现特点。同时评价HRCT在泌尿系结核治疗方案选择中的作用。结果1)36例泌尿系结核患者的HRCT平扫与增强中发现3例早期肾结核,表现为肾实质内小低密度病灶。2)肾内多发花瓣状低密度区25例,肾弥漫性钙化即肾自截2例,肾皮质局限萎缩变薄4例,肾萎缩10例,肾盂或肾盏壁普遍增厚4例。3例腹膜后可见多发性大小不一的淋巴结。3)HRCT平扫加增强,对病灶侵犯脏器和周围组织的范围和程度及肿大淋巴结等进行评价,据此决定手术方式和手术时间。结论肾实质内较小的低密度病灶,肾内多发花瓣状低密度区增强扫描后病变区瓣壁呈环状中度延迟强化,并有不规则钙化是肾结核的影像学特点。依据HRCT影像表现特点可为临床治疗方案的选择提供客观依据。
[Abstract]:Objective to investigate high resolution computed tomography in 36 patients with urinary tuberculosis. HRCT features and the value of imaging in guiding treatment. Methods 36 cases of urinary tuberculosis confirmed by pathology and clinic were analyzed retrospectively. To study the scanning technique of HRCT in urinary tuberculosis. Imaging features of CT plain scan and enhancement. Evaluation of the role of HRCT in the treatment of urinary tuberculosis. Results 1). In 36 patients with urinary tuberculosis, 3 cases of early renal tuberculosis were found on HRCT plain scan and contrast enhancement. There were 25 cases of multiple petal-like low density areas in the kidney, 2 cases of diffuse calcification, 4 cases of focal atrophy and 10 cases of renal atrophy. The renal pelvis or calyceal wall was generally thickened in 4 cases. In 4 cases, multiple lymph nodes of different size could be seen in 4 cases. To evaluate the extent and extent of lesion invasion of viscera and surrounding tissues and the enlarged lymph nodes, and to determine the operation mode and operation time. Conclusion the small low-density lesions in renal parenchyma. Multiple petal-shaped low-density areas in the kidney showed annular moderate delayed enhancement after enhanced scanning. Irregular calcification is the imaging feature of renal tuberculosis. HRCT imaging features can provide objective basis for clinical treatment.

【正文快照】： 泌尿系结核是常见的肺外结核,也是泌尿系统较为常见的疾病,近年来泌尿系结核发病率有增高的趋势。临床影像诊断尤其是早期诊断较为困难,易误诊、漏诊。因而,为提高其诊断率,使用计算机体层摄影术(computed tomography,CT)、CT尿路造影(com-puted tomography urography,CTU)等
