膀胱是适宜于作超声探查的理想器官,作者认为最适宜于探查浸润性膀胱肿瘤,及计算或诊断膀胱容量及/或残余尿量。由于前列腺的位置关系,通过膀胱作前列腺声象图是困难的,在100例中仅产生25％阳性结果,故前列腺的超声应经直肠进行。材料与方法作者用的是横断面显象仪,实时超声扫描器及录象器。病人仰卧,先作中线纵扫描以确定膀胱充盈程度,以决定选用何种技术。让病人正常排尿,并立即作一中线纵扫描及横扫描,横扫描在耻 The bladder is the ideal organ for sonography, which the authors believe is best suited for detecting invasive bladder tumors and for calculating or diagnosing bladder volume and / or residual urine volume. Due to the location of the prostate, sonography of the prostate via the bladder is difficult and produces only 25% of positive results in 100 cases, so ultrasound of the prostate should be performed rectally. Materials and Methods The authors used a cross-sectional imager, real-time ultrasound scanner and video recorder. Patient supine, first for midline longitudinal scan to determine the degree of bladder filling, to decide which technology to use. Allow the patient to urinate normally, and immediately make a midline scan and horizontal scan, scan in shame
