A case of cholesteatoma, clearly delineated by preoperative air contrast retrograde pyelography, was treated like stone disease by removal of the obstructing material from the renal pelvis and pelvic ureter. A 7-year followup suggests that conservative surgical management may be the preferred treatment, since there is no evidence to date that cholesteatoma is a pre-malignant lesion nor necessarily a recurrent condition.
一例胆脂瘤通过术前空气对比逆行肾盂造影清晰显示，像处理结石病一样，通过清除肾盂和肾盂输尿管的阻塞物进行治疗。7年的随访表明，保守手术治疗可能是首选治疗方法，因为迄今为止没有证据表明胆脂瘤是癌前病变，也不一定会复发。
