To prevent papillary tumor from recurring, ligation of the internal iliac arteries was performed bilaterally. 1) Normal bladders of rabbits were examined to find out their distribution of arteries, and then their collateral circulation was explored after having ligated, their superior vesical arteries to examine their histological findings in the course of days. The result is that: The bypaths after the ligation of superior vesical arteries were found running between inferior vesical arteries and inferior mesentric arteries, and inferior vesical arteries and testicular arteries, as supplementary circulation. Hisotological findings were that shedding of the epithelium and atrophy of the smooth coat were seen at the early stage after the ligation, after 25 days the smooth muscle coat began to recover, and that when 2 months passed the muscle coat was normal with only vacuoles and karyopyknosis left on the mucous epithelium. 2) 17 cases of papillary bladder tumor having recurred 2 or 7 times were respectively given simple resection, electrocoagulation, segmental resection of the urinary bladder, or TUR Bt on the tumor. No recurrence has been found yet in any case when they have passed the previous recurring periods. Arteriography of the bladders after the operation was like that of rabbits ; histological findings of the tumor biopsied 20 days after the operation were the presence of vacuoles and karyopyknosis in tumor cells. It is assumed that recurrence of papillary bladder tumor can be prevented if the ligation of the internal iliac arteries is given at the same time when tumor resection is performed.
