DEVELOPMENT OF BENIGN PROSTATIC HYPERTROPHY ESTIMATED FROM ULTRASONIC MEASUREMENTS ON PATIENTS WITH LONG-TERM FOLLOW UP

Abstract

Sixteen cases of benign prostatic hypertrophy (BPH) have been followed up for 6-8 years by size measurements using transrectal-ultrasonotomography. During the observation the weight of the prostate increased in 3 cases but in the remaining 13 it was almost stationary. There was a significant difference between these two patient groups. This means that the weight of hypertrophic prostate is not always increasing with age and suggests that the enlargement of the hypertrophic prostate may occur only in rather short duration.
The distribution of Presumed Circle Area (PCAR) on the horizontal section of the prostate in 16 cases was separated clearly into 2 groups with PCAR over and under 0.80. The former group with high PCAR over 0.80 without significant residual urine should be followed up carefully to clarify the mechanism of urinary disturbance in BPH cases.
