A method of determining the error caused by the infusion of water into the urethra during urethral wall pressure and urethral pressure profile measurements is described and discussed. The test is conducted in vivo and the measured pressure is related to the actual urethral wall pressure. The "intrinsic error" is found to be approximately 1-0 cm H2O for every ml/min of infusion rate. Incidental findings concerned with changes in urethral resistance are also reported.
本文描述并讨论了一种在尿道壁压力和尿道压力分布测量过程中,确定因向尿道注水而导致误差的方法。该测试在体内进行,所测压力与实际尿道壁压力相关。发现“固有误差”约为每毫升/分钟的注水速率对应1 - 0厘米水柱。还报告了与尿道阻力变化有关的偶然发现。
