目的:探讨膀胱内翻性乳头状瘤(IPB)的发病特点,提高对其诊治及预后的认识。方法:回顾性分析1 6例IPB的临床资料,复习相关文献.并随访患者。16例均行经尿道膀胱肿瘤切除术(TURBT),14例术后行膀胱内即刻灌注一次,其中9例继续行膀胱规律灌注1年,另2例未行膀胱灌注。结果:全部病例术后病理诊断均为IPB,其中1例合并低度恶性潜能。随访6个月～5年无复发。结论:膀胱内翻性乳头状瘤是非浸润性泌尿上皮良性肿瘤,TURBT是其标准治疗方法,单纯IPB行TURBT术后无需行膀胱灌注化疗,但需定期随访观察。
Objective: To investigate the incidence of intraductal papilloma (IPB) and improve its diagnosis and prognosis. Methods: The clinical data of 16 cases of IPB were analyzed retrospectively, and the related literatures were reviewed, and the patients were followed up. TURBT was performed in 16 cases and intravesical instillation immediately after operation in 14 cases, of which 9 cases continued to have regular bladder perfusion for 1 year and the other 2 cases did not undergo bladder perfusion. Results: The postoperative pathological diagnosis of all cases were IPB, of which 1 case with low malignant potential. Follow-up 6 months to 5 years without recurrence. CONCLUSIONS: Inverted papilloma is a non-invasive benign tumor of the urothelium. TURBT is the standard treatment for this condition. Bladder chemotherapy is not required after IPB TURBT, but regular follow-up is needed.
