Pseudomembranous trigonitis presents in females with the urethral syndrome and a characteristic lesion restricted to the trigone of the bladder. The histology shows ;vaginal metaplasia' of the epithelium together with underlying oedema and vascular dilatation, but no significant inflammation. Thirty-one such cases are included in the study. The possible role of oestrogen stimulation is discussed, together with a suggestion that the trigone has an embryological derivation distinct from the remainder of the bladder, allowing the trigonal epithelium to respond to oestrogenic stimulation in a manner denied to the vesical transitional epithelium.
假膜性膀胱三角炎见于患有尿道综合征的女性，其特征性病变局限于膀胱三角区。组织学表现为上皮的“阴道化生”，伴有基底水肿和血管扩张，但无明显炎症。该研究纳入了31例此类病例。文中讨论了雌激素刺激的可能作用，并提出膀胱三角区在胚胎学上的起源与膀胱其余部分不同，这使得膀胱三角区上皮能够以膀胱移行上皮所不具备的方式对雌激素刺激作出反应。
