摘　　要：目的探讨经腹超声下测量之膀胱重量(ultrasound estimated bladder weight,UEBW)对前列腺增生膀胱出口梗阻(BOO)的临床意义及与尿动力学指数的相关性。方法来我院就诊的50例有下尿路症状的前列腺患者(排除神经、内分泌系统疾病,无下尿路外伤与手术史)分为膀胱出口梗阻组(B组)和非膀胱出口梗阻(NB组)及对照组(NC组)。比较组间的年龄、IPSS、UEBW、最大尿流率(Qmax)、最大尿流率时膀胱压力的差异。再比较这些参数之间的差异及相关性。UEBW通过将膀胱假想成球体,测量膀胱壁厚度及膀胱体积以计算。结果UEBW:B组(48.6±17.8)g,NB组(29.5±4.7)g,NC组(24.4±4.6)g。B组与NB组及NC组相比较P均小于0.001。结论UEBW可作为一种非侵袭性的诊断膀胱出口梗阻的指标,在临床上有广泛的应用价值。Objective To reveal the possible use of ultrasound estimated bladder weight（UEBW） in evaluating bladder outlet obstruction and the correlation with the urodynamic parameter.Methods A totol number of 50 patients with lower urinary tract symptoms（LUTS） suggestive of BPH（without nervousness disease,endocrine disease,history of operation or external injury of lower urinary tract） and underwent urodynamic studies and the measuremen of ultrasound estimated bladder weight（UEBW）.Among them,9（19%） presented to our department with bladder outlet obstruction（BOO）.From the thickness of the bladder wall measured by transabdominal ultrasonography and the intravesical volume,UEBW was calculated,supposing the bladder to be a sphere.All patients were categorized into B group,NB group and NC（nature control） group.Age,IPSS,UEBW,Qmax,pressur-flow were compared between the groups.Results Between the B group,NB group and NC group,there were significant differences of UEBW：（48.6±17.8）g vs（29.5±4.7）g,（48.6±17.8）g vs（24.4±4.6）g.90.6% of group B had a UEBW greater than 35.0g.Conclusion UEBW would be promising as a noninvasive urodynamic parameter capable of evaluating bladder outlet obstruction.
