Inverted papillomas of the upper urinary tract are rare lesions that have a male predominance. The associated symptoms are similar to those of other urothelial neoplasms. The tumors are considered benign and local excision has been advocated by many but long-term followup is lacking. We present a case of a locally excised inverted papilloma of the renal pelvis with a 3.5-year followup. While local excision appears to be ideal treatment, the difficulty with preoperative diagnosis and the reported coexistence of malignancy demand careful patient selection and close long-term followup. The biological potential of recurrence, multicentricity and malignancy is addressed.
上尿路内翻性乳头状瘤是一种罕见的病变，男性多见。其相关症状与其他尿路上皮肿瘤相似。这些肿瘤被认为是良性的，许多人主张进行局部切除，但缺乏长期随访。我们报告一例肾盂内翻性乳头状瘤局部切除术后3.5年随访的病例。虽然局部切除似乎是理想的治疗方法，但术前诊断困难以及报道的恶性肿瘤共存情况需要仔细选择患者并进行密切的长期随访。本文探讨了复发、多中心性和恶性的生物学潜能。
