Observation of the effectiveness of bladder filling with MMC in preventing recurrence of superficial carcinoma of the bladder

Objective To study the effectiveness of bladder filling with MMC in preventing recurence of superficial carcinoma of the bladder .Methods 78 cases of superficial carcinoma of bladder was treated with bladder filling with MMC following surgical treatment. 40mg of MMC together with 40ml of normal saline was pouring into the bladder for two hours.
