| Popis: | 前立腺肥大症患者88名に対し, 等容性排尿筋圧の測定を行い, その臨床的意義について検討した.1)排尿筋収縮力の低下のために術後の排尿状態が不良であった症例は23例であった.排尿筋収縮力を正しく評価し術後の排尿状態を予測する上で, 最高排尿筋圧が低い症例については最高等容性排尿筋圧が臨床上有用な指標となると考えられた.2)正常者と同じ排尿筋圧を示す前立腺肥大症患者でも病期を異にする患者が混在しており, 最高等容性排尿筋圧を測定することは, 病期を正確に診断する上で有用である The subjects chosen for this investigation were 88 patients with benign prostatic hyperplasia who proved not to have neurogenic bladder and 6 male volunteers without lower urinary tract disorders. In addition to the conventional preoperative urodynamic studies, isometric detrusor pressure was measured by the technique with balloon occlusion at the bladder neck. Although all 88 patients had undergone either transurethral resection of the prostate or subcapsular prostatectomy and routine postoperative examinations revealed sufficient canal formation in the prostatic urethra, in 23 patients (26.1%) a significant amount of residual urine was still observed and/or maximum urinary flow rate was considerably low. A retrospective analysis of the data from this study suggested that maximum isometric detrusor pressure is a useful parameter for the prediction whether or not micturition is improved after the removal of organic lower urinary tract obstruction, especially in cases with low detrusor pressure during urination. Furthermore, measurement of the maximum isometric detrusor pressure might be helpful in making the diagnosis of the clinical stage of benign prostatic hyperplasia, since several different stages could be defined by the value of maximum detrusor pressure during urination and maximum isometric detrusor pressure. |
