摘要
运用三维超声对２３例膀胱壁隆起性病变进行了研究，其中膀胱癌１６例，腺性膀胱炎４例，粘膜慢性炎２例，滤泡状膀胱炎１例；所有病例均行膀胱镜检查或手术治疗，并获病理证实。结果：①体外实验显示三维超声的体积测量与实际容量相关性很好（ｒ＝０．９９８９，Ｐ值＜０．００１）。因此，可用于病变的体积测量，特别对形态不规则的病灶，明显优于两维超声。②能帮助确立病灶与周围组织的解剖关系。③三维表面重建功能能让膀胱壁隆起性病变重建出与大体解剖相似的空间图。尽管三维超声发展时间不长，但是随着该技术的不断发展，它将逐步应用于常规超声检查中，以帮助提高超声诊断水平。
23 urinary bladder wall lesions were investigated by 3-dimensional (3D) sonography, including 16 cases of carcinoma of urinary bladder, 4 glandular cystitis, 2 chronic mucitis and 1 follicular cystitis. Cystoscopic examinations or operations were done in all cases and the diagnoses were confirmed by pathology. The results: 1.It was showed in vitro that the volume measured by 3D sonography correlated with actual volume(r=0.9989, P<0.001), 3D sonography could be used in measuring the volume of the lesions, especially irregular shaped ones the result was more accurate than the volume measured by two-dimensional sonography. 2. It was easy to understand the anatomical relation between the lesion and its surroundings. 3. The imagings constructed by the surface reconstruction of 3D sonography liked the anatomical ones. Although 3D sonography is a new technique, it will be used in conventional ultrasound examination gradually with its development and improves the diagnostic ability ultrasound.
