[Effect of ionizing energy on the bladder dilated by dura, with special reference to the implantation technic. Animal experimental study].

On 60 female rabbits we examined the influence of the postoperative irradiation on the urinary bladder dilated by liophilized human dura after resection of the wall. Compared with former examinations as to the implantation technique the submucous deposition of the dura and fixation with single-button U-sutures (chromic catgut 000) has proved as superior. Vascular trophic disturbances on the margins of the resection could not be proved. When 4,500 R, 6,000 R and 7,500 R were irradiated the regeneration process through the dura serving as "live" rail retarded considerably. Problems in connection with the suture technique and the total focal dosage are discussed taking into consideration literature.
