Scanning electron microscopy was performed on forceps biopsies from 13 patients with catheter-associated polypoid cystitis. Pleomorphic microvilli, which varied considerably in appearance, were found on surface cells of all cases with polypoid cystitis. Practically all of the characteristics of pleomorphic microvilli assigned earlier to bladder tumor cells in humans were identified on specimens from patients with polypoid cystitis. Pleomorphic microvilli were not observed in the bladder biopsies from control patients. The appearance of pleomorphic microvilli was consistent with reversible lesions of the human bladder and they are not specific markers of pre-neoplastic hyperplasia or malignancy.
对13例导管相关性息肉样膀胱炎患者的钳取活检组织进行了扫描电子显微镜检查。在所有息肉样膀胱炎病例的表面细胞上均发现了形态各异的微绒毛，其外观差异很大。实际上，早期赋予人类膀胱肿瘤细胞的多形性微绒毛的所有特征在息肉样膀胱炎患者的标本中均被识别出来。在对照患者的膀胱活检组织中未观察到多形性微绒毛。多形性微绒毛的出现与人类膀胱的可逆性病变一致，它们不是肿瘤前增生或恶性肿瘤的特异性标志物。
