Yang, Seung Choul; Chung, Shung Wha

Abstract

Twenty seven consecutive male and female patients with trigonal cystitis are divided into 2 groups on the basis of the presence or absence of the pseudomembrane(nest of squamous epithelium). One group consists of 15 patients with squamous epithelium and the other of 12 patients with no squamous epithilium on the cystoscopic biopsies from the vesical trigone. The clinical symptoms, physicochemical study and bacteriologic culture of urine, cystoscopic changes and histologic findings are compared between the two groups. 1. Both squamous and non-squamous epithelial groups show no significant differences in the clinical and cystoscopic findings. 2. Pathologic changes of the urothelium and lamina propria of the trigonal mucosa are identical with one to the other group. 3. Trigonal cystits with squamous epithelium occurs most frequently in sexually active premenopausal women and less frequently in the female of post-menopause and even rarely in the male. No age and sex predilection are found in the patients with trigonal cystitis without squamous epithelium.
