In the earlier stagesthe enlarged lateral lobes do notproject into the bladder, but inrare instances they project ante-riorly toward the symphysis pubis, greatly increasing the antero-posterior diameter of the prostate, butforming a prostate the size of which is not indicated either on rectalexamination or with the cystoscope (I have seen two such cases). As arule, however, enlarged lateral lobes soon begin to project into the bladder,where they appear as globular outgrowths covered with smooth mucous. ,^.\^iS Fig. 216.—The Hypertrophy Here is Ad-vanced Still Further Than That Seenin Figs. 214 and 215.

Dissection in suchcases shows that the vesical sphincter lies external to these outgrowths,which have evidently grown into the bladder from the urethra, thus dilatingand pushing the vesical sphincter outward. This is an important point,because it allows the enucleation of these lateral enlargements withoutthe desti-uction of the vesical sphincter. The size reached by such lateralenlargements is often very considerable and occasionally huge. I haveseen cases in which the lateral lobes projected far into the bladder, sothat they presented the appe
