USE OF ALUMINUM SULFATE CO.IN THE TREATMENT OF BLADDER TUMORS

From June 1977 to September 1980. 180 cases of bladder tumors were treated by injecting aluminum sulfate co. into the base of the tumor through cystoscope wth en-couraging results. Two weeks after the initial injection. follow-up cystoscopy was carried out to see whether tumor was completely destroyed. If fhe tumor was not completely destroyed. an additional injection was made to destroy the residual tumor. This treat-ment is effective in non-infiltrating or superficially infiltrating pedunculated papillary tumors. The largest tumor was measured 6 cm. in diameter. 164 of 180 cases thus treated were considered to be cured. The remaining 16 cases required further treatment. because complete destruction was not achieved. No remarkable side-effects were observed during the course of treatment. except for slight local pain. No recurrence was found at the site of the primary tumors.
