Fig. 9, Plate 59.--Two strictures are represented here, the one, e, close to the bulb d, the other, f, an inch anterior to this part. In the prostate, a b, are seen irregularly shaped abscess pits, communicating with each other, and projecting upwards the floor of this body to such a degree, that the prostatic canal appears nearly obliterated. [Illustration] Plate 59.--Figure 9. Fig. 10, Plate 59.--Two bougies, d e, are seen to enter the upper wall of the urethra, c, anterior to the prostate, a b. This accident happens when the handle of a rigid instrument is depressed too soon, with the object of raising its point over the enlarged third lobe of the prostate. [Illustration] Plate 59.--Figure 10. Fig. 11, Plate 59.--Two instruments appear transfixing the prostate, of which body the three lobes, a, b, c, are much enlarged. The instrument d perforates the third lobe, a; while the instrument e penetrates the right lobe, c, and the third lobe, a. This accident occurs when instruments not possessing the proper prostatic bend are forcibly pushed forwards against the resistance at the neck of the bladder. [Illustration] Plate 59.--Figure 11. Fig. 12, Plate 59.--In this case an instrument, d d, after passing beneath part of the lining membrane, e e, anterior to the bulb, penetrates b, the right lobe of the prostate. A second instrument, c c, penetrates the left lobe. A third smaller instrument, f f, is seen to pass out of the urethra anterior to the prostate, and after transfixing the right vesicula seminalis external to the neck of the bladder, enters this viscus at a point behind the prostate. The resistance which the two larger instruments met with in penetrating the prostate, made it seem, perhaps, that a tight stricture existed in this situation, to match which the smaller instrument, f f, was afterwards passed in the course marked out.
