Tests of the integrity of bladder sensation are a poorly understood and often neglected part of urodynamic investigations. The electrical techniques that have been described to test sensation involve the use of costly and complex equipment; electrical current also is not the natural stimulator of bladder nerves. Trigonal sensitivity testing held promise as a simple, effective and inexpensive test of bladder sensation. We evaluated a modified version of this technique in 89 women: 78 had urodynamically proved lower urinary tract dysfunction and 11 were control patients. The technique proved to be of no value in distinguishing among various urodynamic diagnoses. In particular, patients with detrusor instability or bladder hypersensitivity showed no characteristic patterns on trigonal sensitivity testing. Sensitivity values correlated neither with the first sensation to void nor the cystometric bladder capacity during urodynamic testing. It does not appear to contribute any clinically useful information in the evaluation of lower urinary tract dysfunction in women.
膀胱感觉完整性测试是尿动力学检查中一个了解甚少且常被忽视的部分。已描述的用于测试感觉的电技术需要使用昂贵且复杂的设备；电流也不是膀胱神经的天然刺激物。三角区敏感性测试有望成为一种简单、有效且廉价的膀胱感觉测试方法。我们在89名女性中评估了该技术的改良版本：78名经尿动力学证实存在下尿路功能障碍，11名是对照患者。该技术在区分各种尿动力学诊断方面并无价值。特别是，逼尿肌不稳定或膀胱过敏的患者在三角区敏感性测试中未显示出特征性模式。敏感性值与排尿的首次感觉或尿动力学测试期间的膀胱容量测定值均无相关性。在评估女性下尿路功能障碍时，它似乎并未提供任何临床有用信息。
