Establishing accurate initial resting pressures is an important step in quality control at the start of a urodynamics test. We therefore carried out a prospective study to establish the initial resting pressures achievable with careful quality control.
Consecutive patients undergoing urodynamics were recruited. Initial resting pressures were recorded in lying, sitting, and standing positions for each patient. The detrusor pressure values obtained before filling were then compared with the pressures obtained during filling.
Initial resting abdominal and intravesical pressures were similar and at least 95% lay in the following ranges: lying 0-18 cmH(2) O, sitting 15-40 cmH(2) O, standing 20-50 cmH(2) O: these data gave initial resting detrusor pressure readings between -5 and +5 cmH(2) O in 97%, 97%, and 96%, respectively. Comparison of initial resting pressure readings with those obtained during filling showed that the narrow range of pressures was maintained during the urodynamic test.
This study provides detailed prospective data on achievable initial resting pressures in urodynamics. In this study, p(det) was normally at or close to zero, and distributed more or less evenly either side. This suggests a range that differs from existing ICS GUP guidelines, and could be incorporated in future ICS guidelines.
在尿动力学测试开始时，准确确定初始静息压力是质量控制的重要步骤。因此，我们进行了一项前瞻性研究，以确定在严格质量控制下可实现的初始静息压力。
连续招募接受尿动力学检查的患者。为每位患者记录卧位、坐位和立位的初始静息压力。然后比较在充盈前获得的逼尿肌压力值与在充盈过程中获得的压力值。
初始静息腹内压和膀胱内压相似，至少 95%的压力值位于以下范围内：卧位 0-18cmH(2)O，坐位 15-40cmH(2)O，立位 20-50cmH(2)O：这些数据分别在 97%、97%和 96%的情况下给出初始静息逼尿肌压力读数在-5 和+5cmH(2)O 之间。与充盈过程中获得的初始静息压力读数比较表明，在尿动力学测试过程中保持了狭窄的压力范围。
本研究提供了关于尿动力学中可实现初始静息压力的详细前瞻性数据。在本研究中，p(det)通常为零或接近零，并且或多或少均匀地分布在两侧。这表明与现有国际尿控协会指南不同的范围，并且可以纳入未来的国际尿控协会指南。
