Abstract/OtherAbstract:
OBJECTIVE: The purpose of this study was to investigate the value of tumor-bladder wall contact length (CL), tumor height (H), and height-to-length ratio (H/CL) for preoperative staging of bladder carcinoma. METHODS: Fifty-seven patients with bladder tumors underwent suprapubic ultrasonography preoperatively, and the CL of the tumor with the bladder wall and H in the bladder lumen were measured. The CL, H, and H/CL values were correlated with the wall invasion determined by histopathologic analysis of the cystectomy material. Invasion was staged according to the TNM classification system. RESULTS: Statistically significant differences were found for CL (P < .001) and H/CL (P = .001) between the superficial and invasive tumor groups. These parameters were also effective for differentiating superficial or deep muscle invasion. A CL of greater than 41.5 mm and an H/CL of less than 0.605 were calculated as cutoff values for differentiating superficial and invasive tumors. Height had no value for determining invasion. CONCLUSIONS: The ultrasonographic measurements of CL of the tumor with the bladder wall and H/CL may be useful for staging bladder carcinoma by verification of these findings in larger groups of patients.
