A graphic representation of the micturition cycle by a pressure-volume plot has been obtained in 120 women, both incontinent patients and normal controls. The pattern of contraction during voiding allowed prediction of the outcome of treatment. Patients with urethral sphincter incompetence and a sustained detrusor contraction had a good result from colposuspension even if detrusor instability was found during filling. Where the urethral sphincter was competent, patients with urge incontinence with or without detrusor instability during filling cystometry had a good response to drugs, providing a sustained detrusor contraction was present during voiding. Urethral sphincter incompetence was characterised by a low detrusor voiding pressure.
通过压力-容量图对120名女性（包括尿失禁患者和正常对照）的排尿周期进行了图形表示。排尿期间的收缩模式有助于预测治疗结果。尿道括约肌功能不全且逼尿肌持续收缩的患者，即使在充盈期发现逼尿肌不稳定，经阴道膀胱颈悬吊术也能取得良好效果。在尿道括约肌功能正常的情况下，充盈期膀胱测压时有或无逼尿肌不稳定的急迫性尿失禁患者，若排尿时存在持续的逼尿肌收缩，则对药物治疗反应良好。尿道括约肌功能不全的特征是逼尿肌排尿压力低。
