One case of xanthogranulomatous pyelonephritis diagnosed following nephrectomy is described, considering its outstanding characteristics such as male adolescent, right kidney, involvement with normal function and without pathological history for which there is no explanation to date. This disease usually occurs in women 60 years or older, suggesting a renal tumor. In 50% of the cases, urine cultures are positive for Escherichia coli or Proteus mirabilis; in accordance with different reports renal tissue cultures are positive in more than 90%. Malnutrition, calcification, urolithiasis and renal failure with hydronephrosis are common findings. The left kidney is more frequently involved. The etiology is unclear: many hypotheses are discussed, with malnutrition and peroxidase deficit as important causes.
本文描述了一例肾切除术后诊断为黄色肉芽肿性肾盂肾炎的病例，该病例具有一些突出特征，如男性青少年、右肾、功能正常且无既往病史，目前尚无对此的解释。这种疾病通常发生在60岁及以上的女性，易被误诊为肾肿瘤。50%的病例中，尿培养大肠杆菌或奇异变形杆菌呈阳性；根据不同报告，肾组织培养阳性率超过90%。营养不良、钙化、尿路结石以及伴有肾积水的肾衰竭是常见表现。左肾受累更为常见。病因尚不清楚：讨论了多种假说，其中营养不良和过氧化物酶缺乏被认为是重要原因。
