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 cases of bladder wall protuberance were studied by three-dimensional ultrasonography, including 16 cases of bladder cancer, 4 cases of cystitis glandularis, 2 cases of chronic mucosal inflammation and 1 case of follicular cystitis. All cases underwent cystoscopy or Surgical treatment, and confirmed by pathology. Results: ①In vitro experiments showed that the volumetric measurement of three-dimensional ultrasound correlated well with the actual volume (r = 0.9989, P <0.001). Therefore, it can be used for volumetric measurement of lesions, especially for irregularly shaped lesions, which is obviously better than two-dimensional ultrasound. ② can help establish the anatomy of the lesion and surrounding tissue. ③ Three-dimensional reconstruction of the surface of the bladder wall can make the elevation of the disease reconstruction and general anatomy similar to the spatial map. Although the development of three-dimensional ultrasound is not long, but as the technology continues to evolve, it will be gradually applied to conventional ultrasound to help improve the level of ultrasound diagnosis.
