Upper urinary tract (UUT) benign tumours are rare. We present a case of UUT lipoma in a 41-year-old man with left flank pain. A computed tomographic urography scan revealed an irregular thickening of the left renal collecting system wall extending from the upper calices to the renal pelvis. The diagnosis of UUT was made and the patient underwent a nephroureterectomy with bladder cuff excision, as standard treatment. However, macroscopic and histological examination revealed a lipomatous tumour with no sign of malignancy. To our knowledge this is the first reported case of its kind of a UUT managed first with a minimally invasive approach.
上尿路（UUT）良性肿瘤较为罕见。我们报告一例41岁男性因左侧腰痛诊断为上尿路脂肪瘤的病例。计算机断层扫描尿路造影显示左肾集合系统壁不规则增厚，从肾上盏延伸至肾盂。诊断为上尿路肿瘤后，患者接受了标准治疗，即肾输尿管切除术并切除膀胱袖口组织。然而，大体和组织学检查显示为脂肪瘤性肿瘤，无恶性迹象。据我们所知，这是首例首次采用微创方法治疗的上尿路此类病例。
