Application of self-made double-cavity silicone bladder pressure catheter in urodynamics

目的探讨护理人员用自制双腔硅胶膀胱测压导管在临床应用的可行性。为提高前列腺增生患者膀胱测压导管插管成功率,缩短护理人员膀胱测压调试时间,降低目前临床常用嵌段聚醚酰胺树脂材料导管费用支出提供依据和方法。方法将硅胶导尿管进行改良制作成双腔硅胶膀胱测压导管与嵌段聚醚酰胺树脂材料膀胱测压导管(传统导管)进行模拟膀胱压力容积测试进行对比测试;对80例前列腺增生并长期留置尿管的患者分别采用双腔硅胶膀胱测压导管与传统导管进行尿动力学检查,比较2种方法的插管成功率、导管排气便捷率和费用有无差异,并将结果进行相关性分析。结果双腔硅胶膀胱测压导管和传统导管充盈性膀胱测压模拟测试对膀胱压力容积测定和逼尿肌稳定性无显著性差异;2种导管对80例前列腺增生患者进行尿动力学检查时双腔硅胶膀胱测压导管插管一次成功率、导管排气便捷率分别为93.75%(75/80)、97.50%(78/80),优于传统导管的77.50%(62/80)、87.50%(70/80),2组比较差异有统计学意义(χ^2值为7.312、4.414,均P<0.05);双腔硅胶膀胱测压导管费用(134.57±23.58)元明显低于传统导管的(654.78±56.87)元,2组比较差异有统计学意义(t值为-66.505,P<0.05)。结论双腔硅胶膀胱测压导管材料来源广,制作方法简单,成本较低。临床置管操作简单方便,代替传统尿动力膀胱测压导管进行测量有一定的可行性,能够满足临床患者的尿动力学检查,提高了前列腺增生患者插管成功率且减低了患者耗材费用支出,可方便护士及时排除导管内气泡,缩短检测调试时间,提高了护士工作效率,值得在临床推广应用。

Objective To explore the feasibility of clinical application of the self-made double-lumen silicone bladder pressure catheter by nursing staff.To provide a basis and method for improving the success rate of bladder manometry catheter intubation in patients with benign prostatic hyperplasia,shortening the bladder manometry testing time for nursing staff,and reducing the cost of block polyetheramide resin material catheters commonly used in clinical practice.Methods The silicone catheter was modified to make a double-lumen silicone bladder pressure measurement catheter and(traditional catheter)block polyetheramide resin material bladder pressure measurement catheter for simulated bladder pressure volume test for comparison test;80 cases of prostate hyperplasia and long-term indwell patients with urinary catheters were separately tested for urodynamics using a dual-lumen silicone bladder manometry catheter and a traditional catheter,comparing the success rate of intubation,the convenience of catheter exhaustion and the cost of the two methods,and correlating the results.Results There was no significant difference between the dual-lumen silicone bladder manometry catheter and the traditional catheter-filled bladder manometry test for bladder pressure volume measurement and detrusor muscle stability;the two catheters performed double-lumen urodynamic testing in 80 patients with benign prostatic hyperplasia,the one-time success rate of catheterization of silicone bladder pressure measurement catheter and the convenient rate of catheter exhaust were 93.75%(75/80)and 97.50%(78/80)respectively,which were better than traditional catheters 77.50%(62/80)and 87.50%(70/80).The difference between the two groups was statistically significant(χ^2 values were 7.312,4.414,both P<0.05);the cost of the double-lumen silicone bladder pressure measurement catheter was(134.57±23.58)RMB,significantly lower than that of the traditional catheter[(654.78±56.87)RMB],the difference between the two groups was statistically significant(t value was-66.505,P<0.05).Conclusions The dual-cavity silicone bladder pressure measurement catheter has a wide range of materials,simple manufacturing methods and low cost.The operation of clinical catheterization is simple and convenient,and it is feasible to replace the traditional urodynamic bladder manometry catheter for measurement.It can facilitate nurses to remove bubbles in the catheter in time,shorten the detection and debugging time,and improve the efficiency of nurses′work,which is worthy of clinical application.
