経直腸的前立腺縦断法による排尿動能の観察(1)

Abstract

1)前立腺疾患20例に対して前立腺縦断層法による排尿動態の観察を行った.2)本検査によって認識される前立腺の膀胱内突出と膀胱頸部の開大に着目し, これらと排尿困難の程度との相関を自覚症状, 残尿, 最大尿流量率をパラメーターとして統計学的検討を加えた.3)前立腺の膀胱内突出により排尿困難が増強する傾向が弱いながらも認められた.膀胱頸部の開大と排尿困難の間には, より強い関連が認められた.4) A.非突出・開大群, B.突出・開大群, C.非突出・非開大群, D.突出・非開大群の4群に分けるとこの順に排尿状態が悪くなるような印象を受けた

Transrectal longitudinal ultrasonography of the prostate was done for 20 patients with prostatic diseases, 12 with benign prostatic hypertrophy, 6 with bladder neck contracture, and 2 with chronic prostatitis. The intravesical protrusion of the prostate and the opening of the bladder neck, which can be easily recognized by this method, were discussed in relation to dysuria, using subjective symptoms, residual urine, and uroflowmetry (peak flow rate) as parameters. The former was slightly correlated to dysuria, and the latter was definitely correlated to dysuria.
