膀胱重量与前列腺增生临床参数的相关性研究

目的探讨膀胱重量（Bw）与常用BPH临床参数的相关性。方法81例BPH患者分为尿潴留与非尿潴留组，经腹B超（TAUS）测量其BW，将BW与年龄、国际前列腺症状评分（I—PSS）、生活质量评分（QOL）、前列腺体积（PV）、排尿后残余尿（PVR）、最大尿流率（Qmax）和前列腺特异抗原（PSA）进行相关分析。结果81例患者年龄平均（71．73±5．80）岁，IPSS（15．89±3．44）分，QOL（3．88±0．93）分，PV（61．55±19．67）m1．PVR（71．11±30．83）ml，Qmax（9．93±2．74）ml／s，PSA（3．30±2．63）rig／ml，BW（75．85±18．45）g；两组间年龄、QOL、PV、PRV、Qmax、PSA和BW存在显著性差异，而I—PSS差异无显著性；BW与年龄、IPSS、QOL、PV、PRV、PSA呈显著正相关，相关系数分别为（r=0．587，r=0．481，r=0．816，r=0．911，r=0．784，r=0．864，P〈0．001），而与Qmax呈显著负相关（r=-0．769，p〈0．001）。结论BW能反映BPH的严重程度，对指导判断BPH严重程度和外科干预时机可能有重要的临床意义。

Correlation of bladder weight with the clinical parameters in BPH patients

Objectives To study the correlation of bladder weight(BW)with the clinical parameters in BPH patients.Methods 81 BPH patients were derided into two groups.The BW of 81 patients wss measured by transabdominal ultrasound(TAUS)and the clinical parameters were obtained,then comped the conrelation of BW with the clinical parametersincluding the age of patients,the international prostatic symptom score(I-PSS),the prostatic volume(PV),the postvoid residual urine volume(PVR),Qmax,and prostate specific antigen(PSA)].Resuits In all patients,the mean age,IPSS,QOL,PV,PVR,Qmax,PSA and BW was(71.73±5.80),IPSS(15.89±3.44),QOL(3.88 4±0.93),PV(61.55±19.67)ml,PVR(71.11±30.83)ml,Qmax(9.93±2.74)ml/s,PSA(3.30±2.63)ng/ml,BW(75.85±18.45)g respectively;Between patients with and without urirmry retention,the age,QOL.PV,PVB,Qmax,PSA and BW was significant difference,but IPSS was no significant difference.The BW was corrdated significantly with age,IPSS,QOL,PV,PVR and PSA,r was 0.587,0.481,0.816,0.911,0.784,0.864 respectively(P＜0.001);then BW wss correlated significantly with Qmax(r=-0.769,P＜0.001).Conclusions The BW can reflecting the presence and severity of bladder oudet obstruction.The BW assessed by TAUS has important clinical significances to determine the severity of BPH and occasion of surgical intervention.
