前列腺增生症患者剩余尿与膀胱出口梗阻逼尿肌收缩力的相关性研究

目的 :探讨前列腺增生症 (BPH)患者剩余尿 (RUV )与膀胱出口梗阻 (BOO)、逼尿肌收缩力相关性。方法 :对 42例 BPH患者进行尿动力学检查。结果 :RUV与 BOO呈正相关 (r =0 .716 0 ,P <0 .0 1) ,与逼尿肌等容收缩压 (Piso)呈负相关 (r =- 0 .5 718,P <0 .0 1)。术前和术后的 RU V、尿道阻力因子 (URA )的差异有显著性意义 (P<0 .0 5 ) ,而术前和术后的 Piso差异无显著性意义 (P>0 .0 5 )。结论 :BPH患者 RUV的产生及增多是由于 BOO的加重和逼尿肌功能受损的共同结果 ,在病程的不同阶段 ,BOO和逼尿肌收缩力对 RUV的产生、增多及减少具有不同的作用和意义。

The relationship of residual urine, bladder outflow obstruction and detrusor contractility in benign prostatic hyperplasia

Purpose:To assess the relationship of residual urine, bladder outflow obstruction and detrusor contractility in benign prostatic hyperplasia.Method:Urodynamic study was carried out in 42 benign prostatic hyperplasia patients.Results:A significant positive relationship was observed between residual urine and bladder outflow obstruction (r= 0.7160, P< 0.01). And a significant negative relationship was observed between residual urine and detrusor contractility (r=- 0.5718 P< 0.01).Significant differences of RUV and URA between preoperatively and postoperatively were shown (P< 0.05), No sigificant difference of Piso between preoperatively and postopemtively was revealed (P> 0.05).Conclusion:The residual urine volume was changed with increased of bladder outflow obstruction or decreased of detrusor contractility.
