Plate 60.—Figure 9.
Fig. 10, Plate 60.—The prostate presents four lobes of equal size, and all projecting largely around the neck of the bladder. The prostatic canal is almost completely obstructed, and an instrument has made a false passage through the lobe a.
Plate 60.—Figure 10.
Fig. 11, Plate 60.—The third lobe of the prostate is viewed in section, and shows the track of the false passage made by the catheter, d, through it, from its apex to its base. The proper canal is bent upwards from its usual position, which is that at present marked by the instrument in the false passage.
Plate 60.—Figure 11.
Fig. 12, Plate 60.—The prostatic lobes are uniformly enlarged, and cause the corresponding part of the urethra to be uniformly contracted, so as closely to embrace the catheter, d d, occupying it, and to offer considerable resistance to the passage of the instrument.
