目的探讨前列腺增生症（BPH）致膀胱出口梗阻（BOO）的相关问题。方法43例BPH，采用排尿期尿道测压（MUPP）确定膀胱出口梗阻及梗阻程度（以排尿期尿道压力下降梯度MUPPGradient表示），同时行膀胱既等容收缩试验测最大逼尿肌等容收缩压（Piso）；询问并填写国际前列腺症状评分表（IPSS）；经腹壁B超测前列腺体积。结果43例BPH中38例存在BOO（8．37％）；MUPPGradient与IPSS、V、Piso皆呈正相关，相关系数分别为0．5083、0．4472、0．8869。结论BOO是BPH的病理基础，临床症状、逼尿肌代偿与其相关。
Objective To investigate the related problems of bladder outlet obstruction (BOO) caused by benign prostatic hyperplasia (BPH). Methods Forty-three cases of BPH were examined with urinary urethral pressure (MUPP) to determine the extent of bladder outlet obstruction and obstruction (expressed as MUPPGradient of urinary tract pressure drop during urination). The bladder was subjected to isovolumetric contractility test to measure the maximum detrusor isovolumic systolic pressure (Piso); ask and fill in the International Prostate Symptom Score Sheet (IPSS); and transabdominal B-Prostate volume. Results There were 38 cases of BOO (8.37%) in 43 cases of BPH. MUPPGradient was positively correlated with IPSS, V and Piso, and the correlation coefficients were 0.5083, 0.4472 and 0.8869 respectively. Conclusion BOO is the pathological basis of BPH, clinical symptoms, detrusor compensation related.
