The technique of 'simultaneous' urethral pressure profilometry in the bitch is described. Four consecutive recordings were made from each of 100 bitches. From each recording, the maximum urethral closure pressure and functional profile length were measured and assessed for reproducibility. Analyses of variance revealed no significant differences (P greater than 0.2) between the measurements of functional profile length (means: 3.84, 3.84, 3.83, 3.80 cm; standard error of the differences: 0.037) but there were significant variations (P less than 0.001) in maximum urethral closure pressure (means of square roots: 2.26, 2.18, 2.12, 2.08 cm water; standard error of the differences: 0.042). Overall, there was a significant dependence of maximum urethral closure pressure on the measurement order (P less than 0.001). Thus, while functional profile length is a highly reproducible parameter, maximum urethral closure pressure is subject to significant variation.
本文描述了母犬“同步”尿道压力测定技术。对100只母犬中的每只进行了连续4次记录。从每次记录中测量并评估最大尿道闭合压力和功能曲线长度的可重复性。方差分析显示，功能曲线长度测量值之间无显著差异（P>0.2）（平均值分别为3.84、3.84、3.83、3.80厘米；差异标准误为0.037），但最大尿道闭合压力存在显著差异（P<0.001）（平方根平均值分别为2.26、2.18、2.12、2.08厘米水柱；差异标准误为0.042）。总体而言，最大尿道闭合压力显著依赖于测量顺序（P<0.001）。因此，虽然功能曲线长度是一个高度可重复的参数，但最大尿道闭合压力存在显著变化。
