The human urinary bladder wall is traditionally described as being without a muscularis mucosae. A consecutive one year material of 772 bladder biopsies from 171 patients were examined for the proposed presence of lamina muscularis mucosae (MM). MM was observed in 15% of the biopsies and in 35% of the patients and graded into three patterns according to its continuity. Biopsies with transitional cell carcinomas were reviewed in order to find out whether MM-positive biopsies had been staged correctly. The data are discussed in relation to earlier studies on the subject.
传统上认为人类膀胱壁没有黏膜肌层。对171例患者连续一年的772份膀胱活检材料进行检查，以确定是否存在黏膜肌层（MM）。在15%的活检样本和35%的患者中观察到MM，并根据其连续性分为三种模式。对伴有移行细胞癌的活检样本进行复查，以确定MM阳性的活检样本分期是否正确。结合该主题的早期研究对数据进行了讨论。
