urografin-76 and Urinary-Bladder-Neoplasms

In 25 patients suffering from bladder cancer a dynamic computerized tomography was performed under constant conditions in a selected tumor layer level. It was the aim of this study to improve the efficacy of preoperative staging of bladder cancer. In the tumors of stages pT1 and pT2 (12 patients) different courses in the time-density-diagrams were shown in comparison with the stages pT3a + b (13 patients). Furthermore, a different intake and delivery of contrast medium was observed and differences in the vascularization of the individual tumor stages may be suspected. Thereby a separation between operable (pT1/2) and inoperable tumor (pT3a/b) seem to be possible.

Cystoscopy plays a leading role in the diagnosis of bladder tumors. However, in filtration of the bladder wall in depth and the perivesical spreading remains a moot point. Computer tomography (CT) furnishes the opportunity for complex assessment of the stage of bladder tumors. Personal experience is recorded with the study of 43 patients with previously diagnosed bladder tumors. Once the tumor has been verified on surgical intervention, the exactness of CT in determining the T-stage was 88 per cent and of the H-stage--67 per cent. T3-A was the earliest stage susceptible to be demonstrated by CT. The morphologic patterns of perivesical dissemination of the tumors evaluated by CT are described. A scheme is suggested for the place of computer-tomographic examination in assessing the state of patients with bladder tumors.

Twenty cases of malignancies of the bladder and prostate were evaluated by computed tomography. This study was performed in a community hospital adjacent to a large retirement community in Southern California. Although the series was small, the results indicate that, for example, staging of carcinoma of the bladder malignancy beyond Jewitt-Marshall A can be accomplished with some ease using this modality. The extensive malignancies are easily demonstrated and their extents, in relationship to surrounding pelvic structures, are seen with considerable clarity. The use in radiation treatment planning is obvious.
