摘 要:目的分析经腹超声测定前列腺相关指标与尿动力学结果的相关性及在诊断膀胱出口梗阻(BOO)的意义。方法良性前列腺增生患者112例,年龄(69±7)45—85岁。应用经腹超声测定前列腺体积的相关指标,同时行尿动力学检查。将年龄、前列腺3条径线长度、前列腺体积、国际前列腺症状评分(IPSS)等参数与Schafer分级值进行相关性分析。结果前列腺体积、上下径、前后径和左右径分别为(48±29)fnl、(4.3±1.0)cm、(3.7±0.9)cm、(5.2±0.8)cm。最大尿流率(Qmax)、最大尿流率时逼尿肌压力和Schafer分级值分别为(6.2±3.2)mL/s、(56±41)cmH2O、3.1±1.8(0—6),IPSS为23±002(15—31)。Logistic回归分析显示自变量上下径(OR=22.662,P=0.000)、前列腺体积(OR=0.946,P=0.008)、最大尿流率(OR=0.760,P=0.013)对Schafer分级的作用有统计学意义。结论通过经腹超声测定前列腺上下径可初步推断BPH患者的下尿路梗阻情况,尿流动力学检查的Schafer分级可准确评价BOO严重程度。Objective To explore the correlation between the parameters of prostate volume (PV) measured by transabdominal ultrasonography and urodynamic results in diagnosing bladder outlet obstruction (BOO). Methods 112 BPH patients aged 45 -85 underwent transabdominal ultrasonography to measure the superior-inferior diameter ( R1 ) anterior-posterior diameter ( R2 ), and left-right diameter ( R3 ). Urodynamic examination was conducted to record the maximum flow rate (Qmax), detrusor pressure at maximum urinary flow rate (Pdet. Qmax), and detrusor pressure at minimum urinary flow rate (Pdet. Qmin), Schafer grading and international prostate symptom score (IPSS) scores were calculated. Correlation analysis was performed. Results The PV, R1, R2, and R3 were (48 ± 29 ) ml, (4.3 ± 1.0) cm, (3.7 ±0.9) cm, and (5.2 ±0, 8) cm respectively. The Qmax, Pdet. Qmax, Schafer score, and IPSS score were (6.2±3.2) ml/s, (56 ±41) cm H2O, 3.1 ±1.8 (0-6) and 23 ±2 (15-31) respectively. Logistic regression analysis showed that R1 ( OR = 22.662, P = 0.000), PV ( OR = 0. 946, P = 0. 008 ), and Qmax ( OR = 0. 760, P = 0. 013 ) were positively correlated with Schafer grading value. Conclusion The parameters of PV measured by transabdominal ultrasonography are reliable to diagnose BOO due to BPH.
