A minority of women with a subjective complaint of stress urinary incontinence will have negative urodynamic stress incontinence (USI) findings.
To test clinical and ultrasound measures as predictors of an unexpected absence of USI. We hypothesised that unexpectedly negative USI would be more common in young women with good pelvic floor and urethral function.
A retrospective study analysing 398 data sets from women attending a urogynaecology clinic for evaluation of lower urinary tract and pelvic floor dysfunction. Clinical, urodynamic and translabial ultrasound data were tested as possible predictors of negative USI findings.
Women with unexpectedly negative USI findings were younger, had less anterior compartment prolapse and had a higher maximum urethral pressure. Measures of pelvic floor muscle function were not predictive.
Women with unexpectedly negative USI are younger and have better urethral function, but voluntary pelvic floor muscle function seems unrelated to this phenomenon.
少数主观上有压力性尿失禁主诉的女性尿动力学检查结果可能为阴性，不存在压力性尿失禁（USI）。
测试临床及超声检查指标，以预测意外出现的无USI情况。我们假设，在盆底及尿道功能良好的年轻女性中，意外出现的USI阴性情况更为常见。
一项回顾性研究，分析了398例因下尿路及盆底功能障碍到泌尿妇科门诊就诊女性的数据集。对临床、尿动力学及经阴唇超声数据进行测试，以作为USI阴性结果的可能预测指标。
USI检查结果意外为阴性的女性更年轻，前盆腔脏器脱垂程度较轻，最大尿道压较高。盆底肌肉功能指标并无预测价值。
USI检查结果意外为阴性的女性更年轻，尿道功能更好，但盆底肌肉的自主功能似乎与这一现象无关。
