From a statistical viewpoint, almost all renal pelvic tumours may be considered to be transitional cell carcinomas. Only six benign pelvic tumours have been reported in the English literature. The author describes one such case. A 40-year-old woman with recurrent cystitis was found on intravenous pyelography to have a mass in the right renal pelvis. Acting on the assumption that the mass was probably a transitional cell carcinoma, the author performed a nephroureterectomy. The fleshy intrapelvic mass turned out to be an extremely rare benign fibroepithelial tumour.
从统计学观点来看，几乎所有肾盂肿瘤都可被视为移行细胞癌。英文文献中仅报道过6例良性肾盂肿瘤。作者描述了其中1例。一名患有复发性膀胱炎的40岁女性在静脉肾盂造影检查中发现右肾盂有一个肿块。基于该肿块可能是移行细胞癌的假设，作者实施了肾输尿管切除术。结果发现盆腔内的肉质肿块是一种极其罕见的良性纤维上皮肿瘤。
