Fig. 11, Plate 61.—Both lobes of the prostate are enlarged, and from the base of each a mass projects prominently around the vesical orifice, a b. The prostatic urethra has been moulded to the shape of the instrument, which was retained in it for a considerable time.
Plate 61.—Figure 11.
Fig. 12, Plate 61.—The prostate, c b, is enlarged and dilated, like a sac. Across the neck, a, of the bladder the prostate projects in an arched form, and is transfixed by the instrument, d. The prostate may assume this appearance, as well from instruments having been forced against it, as from an abscess cavity formed in its substance having received, from time to time, a certain amount of the urine, and retained this fluid under the pressure of strong efforts, made to void the bladder while the vesical orifice was closed above.
Plate 61.—Figure 12.
Fig. 13, Plate 61.—The lateral lobes, d e, of the prostate are enlarged; and, occupying the position of the third lobe, appear as three masses, a b c, plicated upon each other, and directed towards the vesical orifice, which they close like valves. The prostatic urethra branches upwards into three canals, formed by the relative position of the parts, e, c, b, a, d, at the neck of the bladder. The ureters are dilated, in consequence of the regurgitation of the contents of the bladder during the retention which existed ..
Plate 61.—Figure 13.
Fig. 1, Plate 62, exhibits the lobes of the prostate greatly increased in size. The part, a b, girds irregularly, and obstructs the vesical outlet, while the lateral lobes, c d, encroach upon the space of the prostatic canal. The walls of the bladder are much thickened.
