Objective: To explore the feasibility of simple bladder capacity and pressure measurement in patients with neuro-genic bladder after spinal cord injury(SCI).Method: Sixty SCI patients with neurogenic bladder were measured by simple bladder capacity and pressure measurement and urodynamic monitor for the bladder safe capacity measurement from October 2008 to May 2010 in Department of Rehabilitation and Orthopaedics. A comparison was made between the values obtained through the two test means and the correlationship and test-retest reliability of simple bladder capacity and pressure measurement were analysed.Result: The bladder pressure values under different bladder capacities by the two test means had no statistically significant difference (P>0.05), and as suggested by the correlation analysis, r was 0.78-0.94(P<0.05), It was shown that the two results were better correlated; and under different bladder capacities the intraclass correlation coefficients (ICC, model 2.1) of test-retest on simple bladder pressure measurement were all above 0.8. Conclusion: During lacking of bedside B-ultrasonicimage equipment, simple bladder capacity and pressure measurement is feasible as a replacement of urodynamic monitor testing in determining the bladder capacity of SCI patients.Author's address Dept. Of Rehabilitation Medicine, Gongli Hospital of Pudong New Area,shanghai,200135%探讨简易膀胱容量压力测定在脊髓损伤(SCI)后神经源性膀胱患者康复中的可行性.方法:对我院骨科及康复医学科2008年3月-2010年5月60例SCI后神经源性膀胱患者分别采用简易膀胱容量压力测定法和尿动力学检测仪测量其膀胱安全容量.比较两种方法测量值,以及其相关性和简易膀胱容量压力测定的重测信度.结果:两种方法测量患者不同膀胱容量状态下膀胱压力值差异无显著性意义(P＞0.05)；两组结果相关性分析结果显示r值为0.78-0.94(P＜0.05),呈显著相关；不同容量状态下膀胱压力重测信度系数均＞0.8,示重测信度很好.结论:缺乏床旁B超测定膀胱内容量设备时,简易膀胱容量压力测定法可代替尿动力学监测仪测压法用于SCI患者膀胱容量变化的测量.
