Before discussing the operative results it may be well to say a few words in regard to the differentiation of hypertrophy and carcinoma of the prostate. In making this comparison I have a series of 145 cases of benign prostatic hypertrophy which were exhaustively studied two years ago1 and a series of 111 cases of carcinoma of the prostate which I have recently published.2
In my series of 145 cases of hypertrophy, the prostate was described as distinctly soft in 56, elastic in 26, firm in 45, moderately hard in 14, very hard in no cases. The seminal vesicles were slightly indurated in 19, moderately indurated in 5. Glands were palpable in the pelvis in 5 cases. In my 111 cases of cancer the prostate was soft in 2, elastic in 1, slightly indurated in none, moderately indurated in 6, very hard in 78, stony in 9, in places very hard and in others soft in 10 cases.
