[Endoscopic resection in the treatment of infiltrative bladder tumors. The analysis of a nonselected group of 111 cases].

A total of 111 nonselected cases are presented, of infiltrative urinary bladder tumours, in which endoscopic resections were performed. In most of the cases (83% of the patients) the tumours were of the transitional carcinoma type, the transurethral intervention having been planned in advance. In 35% of the cases resection was done by necessity, and in 3% of the patients resection was done as an emergency for hemostatic purposes. Haemorrhage was the most frequent of the surgical complications, and was reported in 5 patients. Renal failure was the most frequent of the medical complications. In 50 patients radiation therapy was carried out following surgery. The late results are as follows; 44% survivals at 2 years, 14% survival at 3 years, and 9% survivals at 9 years.
