The abilities of single channel cystometry and standard multichannel cystometry to diagnose bladder instability were compared in 100 women taking part in a single blind crossover trial. In 93 of the women both tests yielded the same result. The single channel system detected every case of detrusor instability but in seven women suggested detrusor contractions that were not evident on multichannel cystometry. These were probably due to changes in abdominal pressure. It is concluded that single channel cystometry when used in conjunction with simple urethral tests can provide most of the information that is obtained in specialist centres investigating bladder function.
在一项单盲交叉试验中，对100名女性进行了单通道膀胱测压法和标准多通道膀胱测压法诊断膀胱不稳定的能力比较。在93名女性中，两种测试结果相同。单通道系统检测出了每一例逼尿肌不稳定病例，但在7名女性中提示有多通道膀胱测压法未发现的逼尿肌收缩。这些可能是由于腹压变化所致。结论是，单通道膀胱测压法与简单的尿道测试相结合，能够提供在专业中心研究膀胱功能时所获得的大部分信息。
