Abstract:
It is necessary to understand the age-related growth and development of the human prostate gland because that it was almostly advanced benign prostatic hyperplasia which was the pathologic conditions associated with age and its symptoms tend to be progressive. But there is only a limited information of the natural history of the disease By ultrasonography, we made a study of the changes in prostate with age, the time that initiating benign prostatic hyperplasia and the degree of progression of the disease. The echo pattern, of diameter of the prostate of the maximum anterior-posterior (A-P), superior-inferior(S-I), and transverse(Tr.) were measured in 185 cases from the 20 years to over 80 years of age. The weight of prostate was calculated using formula(W=4/3rr3 X SG, W; weight, SG; specific gravity about 1.05mg/ml, r; radius of prostate in any dimension). The result were as followings. The average prostatic-length were 2.57+/-0.52cm in A-P diameter, 3.44+/-0.35cm in S-I diameter and 4.lO+/-0.02cm in Tr. diameter respectively In the pathologic B.P.H.. the diameter of A-P, S-I and Tr. were 3.72+/-0.35cm, 3.85+/-0.27cm and 4.73+/-0.28cm respectively. The average weight of prostate(gm., mean- S.D.) were 19.16+/-0.35gm in normal adults and 34.43+/-0.47gm in B.P.H. As the age-related events (years), the initial onset of B.P.H. was suspicious in the 5th decades, age that half male population will have pathologic B.P.H. was 62+/-7 years. The average age of onset of clinical symptoms was 63+/-5 years and the average for surgery was 66+/-5 years also.
