【摘要】 目的分析良性前列腺增生(BPH)患者经尿道前列腺汽化电切(TUEVAP)术后膀胱颈挛缩的主要影响因素。方法收集2010年9月至2016年8月芜湖市第一人民医院泌尿外科收治的行TUEVAP术的BPH患者372例,其中术后发生膀胱颈挛缩者44例,首先对TUEVAP术后发生膀胱颈挛缩的相关因素进行单因素分析,再对具有统计学意义的变量进行多因素Logistic回归分析,探寻主要影响因素。结果 372例BPH患者TUEVAP术后发生膀胱颈挛缩者44例(11.8%)。单因素分析结果显示,术者年资、膀胱冲洗液温度、导尿管型号、导尿管堵塞、导尿管气囊注水量及牵引时间是TUEVAP术后膀胱颈挛缩的影响因素(P<0.05)。多因素Logistic回归分析结果显示,导尿管堵塞(95%CI:5.210~487.322)、膀胱冲洗液温度过低(<34℃)(95%CI:10.352~304.260)和导尿管气囊注水量过多(>40 m L)(95%CI:2.551~187.550)是膀胱颈挛缩发生的危险因素(P<0.05)。结论导尿管堵塞、膀胱冲洗液温度(<34℃)和导尿管气囊注水量(>40 m L)是TUEVAP术后发生膀胱颈挛缩的主要影响因素。更多还原

【Abstract】 Objective To analyze the main influence factors leading bladder neck contracture following transurethral electro-vaporization of the prostate(TUEVAP) in patients with benign prostatic hyperplasia(BPH).Methods Three hundreds and seventy-two patients with BPH undergoing TUEVAP from September 2010 to August 2016 in the Department of Urinary Surgery of our hospital were collected, and 44 cases had bladder neck contracture among them. One-way analysis was carried out on the related factors of bladder neck contracture after TUEVAP, and then multifactor Logistic regression analysis was carried out for the variables with statistical significance to explore the main influence factors. Results Forty-four(11.8%) cases with bladder neck contracture were found in 372 patients with BPH undergoing TUEVAP. The one-way analysis showed that the influence factors of bladder neck contracture after TUEVAP were age, the temperature of bladder washing fluid, catheter type, catheter jam,catheter gasbag volume and traction time(P<0.05). The multivariate analysis showed that risk factors of bladder neck contracture after TUEVAP were catheter jam(95%CI: 5.210-487.322), the temperature of bladder washing fluid being too low(<34℃)(95%CI: 10.352-304.260), catheter gasbag volume being too much(>40 m L)(95%CI: 2.551-187.550)(P<0.05). Conclusion Catheter jam, the temperature of bladder washing fluid(<34℃) and catheter gasbag volume(>40 m L) were the main influence factors of bladder neck contracture after TUEVAP.更多还原
