We report a case of milk of calcium renal stone within a calyceal diverticulum in the patient with left ureteral tumor. The patient was a 77-year-old-man with the chief complaint of asymptomatic microscopic hematuria. A plain film revealed round opaque calcific densities in the left kidney in the supine position and a dense crescent-shaped shadow with a horizontal border in the upright position. An intravenous pyelography showed left hydronephrosis and calculi within a calyceal diverticulum. Computed tomography in the supine position revealed layering of the calcifications in cystic lesion of the left kidney accompanied by left hydronephrosis due to a soft mass in the left ureter and a right renal cyst. Retrograde pyelography revealed a filling defect of the middle portion of the left ureter. Under the diagnosis of milk of calcium renal stone and left ureteral tumor, left total nephroureterectomy and partial cystectomy was performed. Pathological findings indicated transitional epithelium of the diverticulum wall and grade 1 transitional cell carcinoma of the left ureteral tumor.
我们报告一例左输尿管肿瘤患者肾盏憩室内的钙乳性肾结石病例。该患者为77岁男性，主诉为无症状性镜下血尿。仰卧位腹部平片显示左肾有圆形不透光钙化密度影，立位时有致密的新月形阴影且边界呈水平状。静脉肾盂造影显示左肾积水及肾盏憩室内有结石。仰卧位计算机断层扫描显示左肾囊性病变内钙化分层，伴有左肾积水，原因是左输尿管有一软组织肿块及右肾囊肿。逆行肾盂造影显示左输尿管中段充盈缺损。在诊断为钙乳性肾结石及左输尿管肿瘤后，行左肾输尿管全切术及部分膀胱切除术。病理结果显示憩室壁为移行上皮，左输尿管肿瘤为1级移行细胞癌。
