The authors modeled the likelihood of death after diagnosis and the probability of cystectomy free survival. All analyses were controlled for age, gender, histology, and year of diagnosis. The most common histologic type was papillary transitional cell carcinoma. The use of total cystectomy and pelvic RT varied among the regions of Ontario. In multivariate analysis, although survival was similar among the regions, the relative risk of cystectomy conditional on survival varied.
Papillary tumors portend a better survival than nonpapillary tumors.
Variations in the use of total cystectomy and in the use of pelvic RT among the regions of Ontario did not appear to be associated with variations in survival. However, cystectomy free survival appeared to vary among the regions. These results suggest that patients can be managed safely using a bladder-preserving approach.

Ten patients with bladder cancer underwent S-CTLA, and the distribution of contrast agent during BOAI into both internal iliac arteries simultaneously was evaluated in nine pairs of internal iliac arteries and one single artery.
