ABSTRACT
The authors analyse treatment results for 88 women suffering from stable dysuria (SD). 44 of them with diagnosis "proliferative cystitis" underwent TUR of the bladder mucosa. The rest were treated conventionally. Biopsy of the bladder was made in all the patients. It is shown that mechanisms of SD development lies in that developing metaplasia of the squamous epithelium prevents close contacts between the surface cells leading to urine penetration into the submucous layer. This provokes frequent and painful micturition. The area of the bladder triangle contains vaginal epithelium (embryological) which changes according to the menstrual phases. Dysuria is more pronounced in the premenstrual period, i.e. in the period of marked desquamation of the squamous epithelial. Desquamation of the surface layer of metaplastic squamous epithelium cells and its thinning ease urine diffusion via intercellular space to the nerves and muscles of the bladder detrusor, thus deteriorating clinical symptoms. Thus, pain in full bladder results from functional failure of metaplastic multilayer squamous epithelium. To eradicate SD in such a situation, TUR of the bladder is recommended.
