A case is presented of gross hematuria and a large polypoid renal pelvic mass in a 15-month-old boy. Operation revealed a Wilms tumor with limited parenchymal involvement and rupture into the collecting system. This rare presentation of nephroblastoma and its differentiation from other rare benign and malignant renal pelvic lesions occurring in the pediatric patient are discussed. The advantages and disadvantages of radical and conservative surgical approaches to these rare lesions are reviewed. Preoperative cystoscopy and retrograde pyelography are mandatory in all patients with renal tumors presenting with gross hematuria, regardless of age. Radical nephrectomy with total ureterectomy is recommended for Wilms tumor with extension into the collecting system.
本文报告了一例15个月大男孩出现肉眼血尿及巨大息肉样肾盂肿块的病例。手术发现是肾母细胞瘤，实质受累有限且已破入集合系统。文中讨论了肾母细胞瘤这种罕见表现及其与小儿患者中其他罕见的良性和恶性肾盂病变的鉴别。回顾了针对这些罕见病变的根治性和保守性手术方法的优缺点。对于所有出现肉眼血尿的肾肿瘤患者，无论年龄大小，术前膀胱镜检查和逆行肾盂造影都是必需的。对于已扩展至集合系统的肾母细胞瘤，建议行根治性肾切除术并切除整个输尿管。
