Crede法排尿与持续导尿对尿路感染和尿道功能影响的研究

目的研究Crede法排尿(间歇人工辅助排尿)与持续导尿对继发尿路感染和远期尿道功能的影响.方法76例神经源性膀胱功能障碍者分别采用Crede法排尿和留置导尿,定期尿液培养进行尿路感染率比较;导尿时间达4～6个月后配合膀胱尿路造影(VCUG)及尿流动力学检查观测尿液返流情况、膀胱颈形态变化和尿道功能指标.结果Crede法排尿组和持续导尿组其尿路感染、尿液返流率分别为16.6%、17.9%和35.1%、40.5%,差异有显著性意义(P＜0.05);VCUG及尿流动力学检查提示持续导尿较C rede法排尿明显损害膀胱颈形态和远期尿道功能.结论对丧失自主排尿功能但无严重意识障碍者宜尽可能减少留置导尿的应用范围和时间,采用Crede法排尿对控制尿路感染、维护和促进排尿功能恢复具有重要意义.

Study on 2 knids method of urinate to the influence in infection and fanction of urethra

Objective Study the Crede method (interspace artificial assitance) urinate and Tupy drainage urine to the influence on infection and fanction of urethra. Method 76 patients with nerves Source bladder dysfunction distinguish toadopt Crede method urinte and Tupy drainage urine,periodical urine educate proceeding urethra infection rate comparison; Last 4-6 months mach with the VCUG and Urodynamics the check urine return appearance incircumstace,bladder variety and urethra function index sign. Results The Crede method and Tupy drinage its urethra infect ion,urine returns rate distinguish for 16. 6%,17.9% and 35. 1%,40. 5%. The difference shows remarkable significane (AO. 05). VCUG and Urodynamics the check hints Tupy drainage urine than Crede method urinate obvious jugular appearance in bladder of damage and long-term the function of urethra. Conclusion To lose autonomic urinate function but have no serious the obstacle of conciousness proper reduce possibly application and time of Tupy drainage urine. Adopt ion Crede method urinate to the contor urethra infect ion,maintenance and promote urethra function instauration have the cardinal meaning.
