BLADDER
Tumor.
—Wishard, Hamer and Mertz37 stated that the malignancy of tumors of the bladder can be graded 1 in about 30 per cent of such cases. The most common type of growth on this organ is that which is on a broad, sessile, infiltrating base. A few vigorous endoscopic treatments have been found to give the best results if the tumor is not too large or too broad at the base. Suprapubic resection and electrocoagulation should be employed only if subsequent cystoscopy indicates that progress is unsatisfactory and provided the tumor is in a resectable region. With the modern prostatic electrotome, large masses of neoplastic tissue, which formerly required open operation, can be removed from the bladder. Open operations which necessitated massive electrocoagulation and application of radium were performed by the authors in about 30 per cent of cases of tumor of the bladder. Fifty per cent of
