To predict the duration of postoperative bladder drainage required after incontinence surgery, 30 patients were studied preoperatively using voiding-simultaneous urethrocystometry. Based on changes in bladder, urethral, and abdominal pressures, patients were divided into three groups. Patients who demonstrated adequate bladder contraction during voiding did not need prolonged catheterization (P less than .005). Patients who did not demonstrate adequate detrusor contraction and used Valsalva maneuver during voiding were at 12 times greater risk of requiring prolonged postoperative catheterization (P less than .05). Changes observed in urethral and abdominal pressures individually during voiding were not significant predictors of the need for prolonged catheterization. Preoperative knowledge of voiding mechanisms can predict postoperative catheterization need.
为预测尿失禁手术后所需的膀胱引流持续时间，术前对30例患者采用排尿同步尿道膀胱测压法进行研究。根据膀胱、尿道和腹部压力的变化，将患者分为三组。排尿时膀胱收缩良好的患者无需长时间留置导尿管（P<0.005）。排尿时逼尿肌收缩不佳且采用瓦尔萨尔瓦动作的患者术后需要长时间留置导尿管的风险高12倍（P<0.05）。排尿时单独观察到的尿道和腹部压力变化并非长时间留置导尿管需求的显著预测指标。术前了解排尿机制可预测术后导尿管留置需求。
