The acutevery often passes into a chronic stage, in which the secretion becomesvery scanty, is composed principally of young epithelial cells, andalso contains but few gonococci. At this stage an infiltration isfound in the superficial layers of the mucous membrane which 308 THE URINARY DISCHARGING APPARATUS consists of mononuclear round cells and of epithelioid cells, and which also penetrates deeper along the lacunae and the ducts of Littres glands, even reaching into the corpus cavernosum, and eventually changes into shrinking connective tissue (Fig. 152, &).

At the same time the lacunae and Littresglands may be destroyed (<^), owing to the change of the cellularinfiltration situated immediately around them and between the aciniof the glands into a contracting cicatrix. Under certain circum-stances, notably when the cicatricial tissue extends into the corpuscavernosum, a narrowing or stridiire of the urethra may even result.If in the presence of strictures wounds of the urethra ha
