RESUMO
What we know an actual length of the prostatic urethra is a valuable implement for evaluating on urological conditions of prostatic gland, such as the prostatic hyperplasia, prostatic tumor and other disorders of the prostatic gland. The urological discipline concerned with this, usually known nowadays as cystourethrography, has therefore a key position in evaluating of the length of prostatic urethra clinically. The author performed a cystourethrograph on 20 cases of Korean adults, and measured the length of prostatic urethra on urogram which was made by radiology with a metric system. Results are as follows: 1) Average length of the prostatic urethra on the antero-posterior view was 4.48+/-0.373 (M+/-S.D.) 2) On the right oblique view, average length of prostatic urethra was 4.80+/-0.403 (M+/-S.D.) 3) On the left oblique view, average length of prostatic urethra was 4.85+/-0.419 (M+/-S.D.)
