Objective: To investigate the clinical features, pathology, diagnosis and treatment of Inverted urothelial papilloma. Methods; A total of 43 cases of urothelial inverted papilloma were analyzed retrospectively,of these cases,35 were male and 8 were female,with a mean age of 57 years old. Most patients complained of painless gross he-maturia. The diagnosis could be established mainly by ultrasonic, cystoscope and pathology. 41 were treated by tran-surethral bladder tumor resection (TURBT) , among which 4 cases accompanying benign prostatic hyperplasia were treated by transurethral prostatic resection, 1 by partial cystectomy, 1 by cyst irrigation. Results: 35 cases were followed up for 12 months to 64 months ( mean 25 months). Intravesical recurrence was found in 5 cases,of them 4 cases underwent TURBT,and 1 case underwent total cystectomy. Conclusion; Bladder inverted urothelial papilloma is a benign tumor. TURBT is the preferred treatment choice for inverted papilloma of the bladder, Although this disease has a good prognosis, regular follow - up observations are necessary. Irrigation therapy could not reduce the risk of recurrence.%目的:探讨膀胱内翻性乳头状瘤的临床表现、病理类型及临床诊治方法.方法:回顾性分析2004年3月至2011年6月,我院收治膀胱内翻性乳头状瘤43例,其中男35例,女8例,平均年龄57岁.临床表现主要为无痛性肉眼血尿,下尿路症状及体检发现.诊断依据泌尿系超声,膀胱镜检及病理检查,41例行经尿道膀胱肿瘤切除(TURBT),其中4例合并良性前列腺增生者同时行经尿道前列腺切除术,膀胱部分切除术1例,未手术治疗仅行膀胱灌注1例.结果:35例随访12个月- 64个月,平均25个月.5例复发,其中4例再次行TURBT术,1例行膀胱全切治疗.结论:膀胱内翻性乳头状瘤是良性肿瘤,多见于男性,TURBT是膀胱内翻性乳头状瘤的首选治疗方法,预后良好,复发率低,膀胱灌注未见明显降低其复发率.但需定期随访.
