THE SURGICAL SPREAD OF CANCER IN UROLOGY1

Abstract

SUMMARY Six cases of recurrence of carcinoma of the bladder occurring in the urethra are presented. Three of these were in the posterior and three in the anterior urethra. Another five cases are presented which developed metastases in the prostatic cavity after a prostatectomy had been performed in the presence of a carcinoma of the bladder. Fifteen cases of recurrence of carcinoma of the bladder in the scar of an open operation are discussed. After approximately 5 per cent. of open operations on the bladder the first recurrence was in the scar. Methods of preventing implantation metastases from urinary cancer are discussed.
