Urethral catheterization, the standard method for measurement of bladder volume, is associated with patient discomfort plus the risks of urethral trauma and urinary tract infection. A portable ultrasound instrument that automatically determines bladder volume was used for 164 determinations and the digital readout correlated with the catheterized volume (r2 equals 0.79). This instrument is a noninvasive alternative to urethral catheterization for the determination of bladder volume in most patients.
导尿术是测量膀胱容量的标准方法，但会给患者带来不适，还存在尿道创伤和尿路感染的风险。一台能自动测定膀胱容量的便携式超声仪器被用于164次测量，其数字读数与导尿测得的容量相关（r2等于0.79）。对于大多数患者来说，该仪器是一种用于测定膀胱容量的非侵入性替代导尿术的方法。
