Abstract

OBJECTIVE

To evaluate the clinical application value of the bladder outlet obstruction index (BOOI) in the diagnosis of BPH.

METHODS

We retrospectively analyzed the urodynamic parameters and BOOI of 199 cases of BPH diagnosed from July 2016 to September 2018, which were divided into a BOO (n = 119), a suspected BOO (n = 39) and a non-BOO group (n = 41) based on the BOOI. We obtained the prostate volume (PV), IPSS, IPSS-voiding symptom score (IPSS-VS), quality of life score (QOL), maximum urinary flow rate (Qmax) and postvoid residual urine volume (PVR) from the patients, compared them among the three groups and analyzed their correlation to BOOI using Pearson's linear correlation analysis.

RESULTS

No statistically significant differences were observed in age (P = 0.195), PSA (P = 0.380), IPSS (P = 0.380), IPSS-VS (P = 0.380), QOL (P = 0.380), Qmax (P = 0.380) and PVR (P = 0.912) among the three groups of patients, but PV was remarkably larger in the BOO than in the suspected BOO and non-BOO groups (［58.8 ± 30.0］ vs ［49.8 ± 33.9］ and ［45.5 ± 26.0］ ml, P = 0.031). Pearson's linear correlation analysis showed that BOOI was not correlated significantly to IPSS (r = －0.020, P = 0.778), IPSS-VS (r= －0.013, P = 0.853), QOL (r = －0.107, P = 0.132), Qmax (r = －0.130, P = 0.066) or PVR (r = －0.056, P = 0.433), nor obviously to PV (|r| = 0.178<0.4) though with P = 0.012.

CONCLUSIONS

BOOI is not significantly correlated to PV, IPSS, IPSS-VS, QOL, Qmax or PVR, and therefore BOO cannot be diagnosed exclusively with BOOI.

摘要

目的

评估膀胱出口梗阻指数（BOOI）在良性前列腺增生（BPH）诊断中的临床应用价值。

方法

回顾性分析2016年7月至2018年9月诊断为BPH的199例患者的尿动力学参数和BOOI，根据BOOI将其分为膀胱出口梗阻（BOO）组（n = 119）、疑似膀胱出口梗阻组（n = 39）和非膀胱出口梗阻组（n = 41）。获取患者的前列腺体积（PV）、国际前列腺症状评分（IPSS）、排尿症状评分（IPSS-VS）、生活质量评分（QOL）、最大尿流率（Qmax）和残余尿量（PVR），比较三组间上述指标，并采用Pearson线性相关分析其与BOOI的相关性。

结果

三组患者在年龄（P = 0.195）、前列腺特异抗原（PSA）（P = 0.380）、IPSS（P = 0.380）、IPSS-VS（P = 0.380）、QOL（P = 0.380）、Qmax（P = 0.380）和PVR（P = 0.912）方面差异均无统计学意义，但BOO组的PV明显大于疑似BOO组和非BOO组（［58.8 ± 30.0］ vs ［49.8 ± 33.9］和［45.5 ± 26.0］ml，P = 0.031）。Pearson线性相关分析显示，BOOI与IPSS（r = －0.020，P = 0.778）、IPSS-VS（r = －0.013，P = 0.853）、QOL（r = －0.107，P = 0.132）、Qmax（r = －0.130，P = 0.066）或PVR（r = －0.056，P = 0.433）均无显著相关性，与PV虽有相关性（|r| = 0.178<0.4），但P = 0.012，相关性不明显。
