目的 总结黄色肉芽肿性肾盂肾炎的诊断要点及易患因素,提高术前诊断准确率。 方法 回顾2002年12月1日-2012年12月1日大连医科大学3所附属医院13例术后病理诊断为黄色肉芽肿性肾盂肾炎患者的既往病史、临床表现、实验室检查及影像学表现特点。 结果 最常见的临床表现及体征为腰痛、体重下降和贫血貌;13例术前运用CT进行评估,诊断符合率为23.1%。9例尿培养阳性。病程长(≥1年)者易发展为弥漫型。 结论 黄色肉芽肿性肾盂肾炎临床症状常不典型,容易误诊为肾肿瘤或肾结核;CT是XGP术前诊断及术前评估最有效的影像学检查之一。 |

Abstract: |
Objective Xanthogranulomatous pyelonephritis(XGP) is an uncommon disorder that is characterized by extensive destruction of the involved kidney. The aim of this study was to examine clinical characteristics, risk factors and diagnosis of the disease. Methods This retrospective study was undertaken to review the xanthogranulomatous pyelonephritis cases presented at three affiliated hospitals of Dalian Medical University in Dalian ,China from December 1, 2002 to December 1, 2012. Results A total of 13 pathology-proven cases of xanthogranulomatous pyelonephritis from December 2002 to December 2012 treated at the institute were included in the study. There were 10 females and 3 males with a mean age of 40.25 years. Flank pain was the most common presenting symptom followed by weight loss and pallor. Computed tomography (CT ) was used to evaluate the 13 cases before surgery and the diagnostic coincidence rate was 23.1%. Urine culture was positive in 9 cases. Patients with diffuse form of XGP had a longer duration(≥1 year). Conclusion The clinical symptoms of XGP is atypical and mimic renal tumor or renal tuberculosis. The ability to diagnose XGP preoperatively will considerably improved with the use of computed tomography (CT). |
