Fig. 5, Plate 61.—The prostate, d, is considerably enlarged, and the vesical orifice is girt by a prominent ring, b b, from the right border of which the nipple-shaped body, a, projects and occupies the outlet. Owing to the retention of urine caused by this state of the prostate, the ureters, c c, have become very much dilated.
Plate 61.—Figure 5.
Fig. 6, Plate 61.—The lateral lobes of the prostate, c c, are seen enlarged, and from the inner side and base of each, irregularly shaped masses, a, b, d, project, and bend the prostatic urethra first to the right side, then to the left. The part, a, resting upon the part, b, acts like a valve against the vesical outlet, which would become closed the tighter according to the degree of superincumbent pressure. A flexible catheter would, in such a case as this, be more likely, perhaps, to follow the sinuous course of the prostatic passage than a rigid instrument of metal.
Plate 61.—Figure 6.
Fig. 7, Plate 61.—A globular mass, a, of large size, occupies the neck of the bladder, and gives the vesical orifice, c, a crescentic shape, convex towards the right side. The two lobes of the prostate, b, are much enlarged.
