Abstract

OBJECTIVES

To determine the effect of intravesical protrusion of the prostate (IPP, graded I to III) on lower urinary tract function, by correlating it with the results of a pressure-flow study.

PATIENTS AND METHODS

In a prospective study men (aged> 50 years) with lower urinary tract symptoms were initially evaluated as recommended by the International Consultation on Benign Prostatic Hyperplasia, together with the IPP and prostate volume, as measured by transabdominal ultrasonography. These variables were then correlated with the results from a pressure-flow study.

RESULTS

The IPP was a statistically significant predictor (P < 0.001) of bladder outlet obstruction (BOO) compared with other variables in the initial evaluation. In all, 125 patients had significant BOO, defined as a BOO index of> 40. Of these men, 94 had grade III and 30 had grade I-II IPP. Seventy-five patients had a BOO index of < 40; 69 had grade I-II and six grade III IPP. In patients with BOO confirmed on the pressure-flow study, grade III IPP was associated with a higher BOO index than was grade I-II (P < 0.001).

CONCLUSION

The IPP assessed by transabdominal ultrasonography is a better and more reliable predictor of BOO than the other variables assessed.

摘要

目的

通过将前列腺膀胱内突出（IPP，分级为I至III级）与压力-流率研究结果相关联，确定其对下尿路功能的影响。

患者与方法

在一项前瞻性研究中，对有下尿路症状的男性（年龄>50岁）按照良性前列腺增生国际咨询会议的建议进行初始评估，同时测量经腹部超声检查的IPP和前列腺体积。然后将这些变量与压力-流率研究的结果相关联。

结果

与初始评估中的其他变量相比，IPP是膀胱出口梗阻（BOO）的统计学显著预测指标（P<0.001）。共有125例患者存在显著的BOO，定义为BOO指数>40。在这些男性中，94例为III级IPP，30例为I-II级IPP。75例患者的BOO指数<40；69例为I-II级，6例为III级IPP。在压力-流率研究中确诊为BOO的患者中，III级IPP的BOO指数高于I-II级（P<0.001）。
