Application of self-made double-cavity silicone bladder pressure catheter in urodynamics / 中国实用护理杂志

ABSTRACT

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 ( χ2 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.
