Influence of changes in renal pelvic pressure on postoperative fever during minimally invasive percutaneousnephrolithotomy
微创经皮肾镜取石术中肾盂内压变化对术后发热的影响

摘要

目的 探讨行微创经皮肾镜取石术患者术后发热与术中肾盂内压变化之间的关系。方法 此次研究共选取95例患者，均行微创经皮肾镜取石术，其中19例有发热表现，在术中实时测量其肾盂内压指标情况，所应用的设备为压力传感器，对所整合的数据信息进行分析统计两者之间的关联性。结果 经相关数据表明，19例患者在术后体温≥38.5℃，在分析后可见术后发热与性别、年龄、尿路感染、术后血常规白细胞、术中肾盂内压≥40mmHg等因素不相关，感染性解释、通道大小、术中平均肾盂内压≥20、30mmHg等是导致患者发热的主要因素，并且若患者在手术过程中肾盂内压≥30mmHg持续时间高于50秒时其术后发热概率会明显提升。结论 对于行微创经皮肾镜取石术患者而言，若术中肾盂内压≥30mmHg持续50秒以上会使得术后发热情况显著增加，术中肾盂内压的短暂性提升对其影响并不大。

Abstract

Objective To investigate the relationship between postoperative fever and changes in intraoperative renal pelvis pressure in patients undergoing minimally invasive percutaneous nephrolithotomy.
Methods A total of 95 patients were selected in this study, all of whom underwent minimally invasive percutaneous nephrolithotomy, and 19 of them had fever, and the internal pressure of the renal pelvis was measured in real time during the operation. The equipment used was a pressure sensor. The integrated data information is analyzed to count the correlation between the two.
Results According to relevant data, 19 patients had postoperative body temperature ≥ 38.5 ℃. After analysis, it can be seen that postoperative fever was not related to factors such as gender, age, urinary tract infection, postoperative blood routine white blood cells, and intraoperative renal pelvis pressure ≥ 40mmHg. Correlation, infectious explanation, channel size, intraoperative mean renal pelvis pressure ≥ 20, 30mmHg, etc. are the main factors leading to fever in patients, and if the patient’s renal pelvic pressure ≥ 30mmHg lasts for more than 50 seconds during the operation, his postoperative The probability of fever will increase significantly.
Conclusion   For patients undergoing minimally invasive percutaneous nephrolithotomy, if intraoperative renal pelvic pressure ≥ 30 mmHg lasts for more than 50 seconds, postoperative fever will increase significantly. not big.
