We studied the intravesical pressure profile and the fluid absorption in 30 men undergoing transurethral resection of the prostate with the irrigating fluid bags placed 55-60, 70-75, 80-85 or 90-100 cm above the operating table. The maximum intravesical pressure, but not the mean pressure or the period of time during which there was excessive pressure (> 2 kPa), increased when the fluid bags were placed higher. The urologist consistently reached about half the possible maximum pressure as indicated by the bag height at the end of each intermittent filling of the bladder. A large bladder capacity promoted lower maximum and mean pressures and shortened the period of excessive intravesical pressure. However, neither bag height nor bladder capacity correlated with the absorption of irrigating fluid.
我们研究了30名接受经尿道前列腺切除术的男性患者的膀胱内压力曲线和液体吸收情况，这些患者的冲洗液袋放置在手术台上方55 - 60厘米、70 - 75厘米、80 - 85厘米或90 - 100厘米处。当冲洗液袋放置得更高时，膀胱内最大压力升高，但平均压力或压力过高（> 2 kPa）的时间段并未增加。在每次间歇性膀胱充盈结束时，泌尿科医生所达到的压力始终约为冲洗液袋高度所指示的最大可能压力的一半。膀胱容量大时，最大压力和平均压力较低，且膀胱内压力过高的时间段缩短。然而，冲洗液袋高度和膀胱容量均与冲洗液的吸收无关。
