良性前列腺增生症患者尿动力学特点

Urodynamic features in BPH

目的 :探讨良性前列腺增生 (BPH)患者尿动力学特点。方法 :就 474例 BPH患者的尿动力学资料 ,分析 BPH患者膀胱出口梗阻 (BOO)比例及其与最大尿流率 (Qmax)、排尿后剩余尿量 (PVRV)的关系 ;BOO(+)、BOO(- )和 BOO(± )患者间以及不同梗阻程度患者间的膀胱功能变化特点。结果 :75 .11%的 BPH患者存在BOO;BOO(+)组 Qmax明显低于其余两组 (P <0 .0 1) ,其 PVRV明显高于另两组 ;BOO (+)组的逼尿肌痉挛发生率显著高于其余两组 (P <0 .0 1) ,但不同梗阻程度患者间差异无显著性意义 (P >0 .0 5 ) ;逼尿肌顺应性降低和逼尿肌亢进在 BOO(+)组的发生率高于其余两组 (P <0 .0 5 ) ,且随梗阻程度加重 ,其发生率明显升高 (P <0 .0 0 5 ) ;逼尿肌收缩力减弱在 BOO(- )组的发生率显著高于另两组 (P<0 .0 0 5 )。结论 :Qmax和 PVRV的变化除受到 BOO的影响外 ,可能与逼尿肌功能状况有更直接的关系 ;逼尿肌痉挛、逼尿肌顺应性降低及逼尿肌亢进的发生率与

Purpose:To analyze the urodynamic features of BPH patients.Methods:The qualified urodynamic results of 474 BPH patients were admitted in the study.The ratio of BOO patients to all cases and each value of Q max and PVRV in every group were calculated. The features of detrusors in patients with different extent of BOO were analyzed.Results:①366 out of 474 ( 75.11 %) patients had BOO.②The value of Q max , PVRV in BOO(+) group were statistically lower and higher respectively than that of BOO(-) and BOO(±) group (P< 0.01 ), but there were no statistically differences among different BOO groups (P> 0.05 ).③There were statistically more patients with detrusor spasm, decreased bladder compliance and detrusor hypercontractility in BOO group than those in other two groups (P< 0.05 ).④DSD didn′t have positive relationship with BOO (P> 0.05 ).⑤Detrusor hypocontractility was dominant in BOO(-) group (P< 0.005 ).Conclusions:Q max and PVRV may have stronger correlation with detrusor function state than with BOO.There were positive correlation between detrusor spasm and BOO, decreased bladder compliance and BOO, detrusor hypercontractility and BOO.
