前列腺突入膀胱距离与尿动力学棋盘法的相关性研究

The correlation between intravesical prostate protrusion and chess classification of urodynamics

目的:探索尿动力学棋盘法足点、曲率与前列腺突入膀胱距离(IPP)的相关性,进一步分析前列腺增生症(BPH)患者的IPP和膀胱出口梗阻(BOO)的关系。方法:选取符合手术适应证且行经尿道前列腺等离子切除术的BPH患者59例,压力流率检测计算棋盘法足点和曲率,经腹超声测量前列腺体积(PV)和IPP,了解足点和曲率与IPP程度的相关性,分析IPP和PV在评估BOO的差异。结果:IPP与足点之间存在正相关关系(P<0.05);IPP与曲率之间不存在相关关系(P>0.05);无BOO(NBOO)患者IPP显著小于BOO患者的IPP(P<0.05);NBOO患者与BOO患者的PV比较差异无统计学意义(P>0.05)。结论:棋盘法足点与IPP存在正相关关系,而IPP与曲率之间不存在相关关系,IPP相较PV能够更准确评估BPH患者BOO程度。

Objective:To investigate the correlation between the footpoint and curvature of chess classification and intravesical prostate protrusion(IPP)in patients with benign prostate hyperplasia(BPH),and further analyze the relationship between IPP and bladder outlet obstruction(BOO).Methods:59 BPH patients underwent transurethral plasma resection of prostate were selected,the footpoint and curvature of chess classification was calculated by pressure-flow test in urodynamic study while prostate volume(PV)and IPP was measured by transabdominal ultrasound to understand the correlation between footpoint and curvature of chess classification and IPP so as to determine the differences between IPP and PV in assessing the degree of BOO.Results:There was a positive correlation between IPP and footpoint(P<0.05)but no correlation between IPP and curvature(P>0.05).IPP of patients with no bladder outlet obstruction(NBOO)was significantly less than that of patients with BOO(P<0.05),while no difference of PV was detected between BOO patients and NBOO patients(P>0.05).Conclusion:The positive correlation has been proved between IPP and footpoint in chess classification,but no correlation between IPP and curvature has been found.Compared with PV,IPP is more accurate in assessing the degree of BOO in BPH patients.
