A group of 163 patients attending with a naturally full bladder had urethrocystometric assessment during provocation with a handwashing test. The results were compared with those from a similar group of 169 patients who were subjected to a handwashing test following the infusion of 500 ml of saline with fast-fill cystometry. The latter group was found to have an unacceptably high number of false-positive results. Also, the results appear to indicate that urine loss due to uncontrolled detrusor contraction may be mainly due to premature activation of the micturition reflex. A fall in the intraurethral pressure was found in 79% and a rise in detrusor pressure in 49% of the patients presenting with a prior history of an unstable bladder. Natural urethrocystometry appears to be a useful and informative technique for objectively assessing patients with a prior history of bladder instability.
一组163名膀胱自然充盈的患者在进行洗手试验激发时接受了尿道膀胱测压评估。将结果与另一组169名类似患者的结果进行比较，后者在输注500毫升生理盐水并进行快速充盈膀胱测压后接受了洗手试验。发现后一组的假阳性结果数量高得令人无法接受。此外，结果似乎表明，由于逼尿肌不受控制的收缩导致的尿液流失可能主要是由于排尿反射的过早激活。在有膀胱不稳定既往史的患者中，79%的患者尿道内压下降，49%的患者逼尿肌压力升高。自然尿道膀胱测压似乎是一种有用且信息丰富的技术，可用于客观评估有膀胱不稳定既往史的患者。
