Abstract：
OBJECTIVE: Following transurethral resection of the prostate (TURP), there is no clear recommendation for the catheter duration, and objective criteria are needed to determine appropriate time for trial off catheter. Current study is aimed to identify the high-risk patients for failed trial off catheter and the association with preoperative voiding efficiency with postoperative failed trial without catheter.
METHODS: This is cross-sectional single institutional study. All eligible patients who underwent TURP were followed preoperatively for symptoms and workup, including voiding efficiency based on ultrasound findings, intraoperatively for resection parameters, and postoperatively for a trial off a catheter. All the findings were documented, and the data were analyzed on SPSS(TM) 22. Demographic variables were calculated in the form of frequency and percentages. The association of voiding efficiency with failed trials off catheters was checked through Chi-square and binary logistic regression analysis.
RESULTS: 132 patients were included in the study. The mean voiding efficiency was 57.5%. Based on voiding efficiency cut off, of 50%, patients were divided into two groups. The association between voiding efficiency and failed trials off catheters was not found to be statistically significant, with a p value of 0.79. Only prevoid volume, postvoid volume, duration of symptoms, and upper tract damage were found to be statistically significant predictors of failed trial off catheter, with a p value of < 0.05.

摘要：
目的：经尿道前列腺电切术（TURP）后，对于导管的持续时间没有明确的建议,并且需要客观标准来确定导管试验的适当时间。目前的研究旨在确定导管外试验失败的高危患者，以及术前排尿效率与术后无导管试验失败的关系。
方法：这是一个跨领域的单机构研究。所有符合条件的患者接受TURP术前随访症状和检查，包括基于超声检查结果的排尿效率，术中切除参数，术后进行导管试验。所有的发现都记录在案,数据在SPSS(TM)22上进行分析。人口统计学变量以频率和百分比的形式计算。通过卡方和二元逻辑回归分析检查了排尿效率与导管失败试验的关联。
结果：132名患者被纳入研究。平均排尿效率为57.5%。基于排尿效率切断，50%,将患者分为两组。排尿效率与导管试验失败之间的关联未发现有统计学意义。p值为0.79。只有前空体积，后空隙体积,症状持续时间，和上消化道损伤被发现是失败的导管试验的统计学显著预测因素，p值<0.05。
