Text Appearing Before Image:
nby surface applications, the device here described has been made andsatisfactorily employed in the treatment of malignant tumors of the uri-nar\ bladder. AVith the exception of a special device to implant radiumemanation into tumors of the bladder all other instruments employedfor radium treatment of malignant tumors of the urinary bladder, by wayof the urethra, have been employed for the purpose of applying radiumto the surface of the tumor mass rather than within its substance. In developing the present instrument there has been a desire to avoidmaking a special cystoscope for the purpose of imjjlanting the radiumwithin the tumor. Instead, the new device can be used through theBrown-Beurger operating cystoscope, as are the other instruments com-monly employed with this instrument. The device itself (Fig. i) consists of a solid metal block mountedon a flexible shaft, similar to the shaft emploved in other cystoscopicoperating instruments. Into this metal block are screwed two radium

Radium 41 needles which contain amounts of radium up to 15 milligrams; the sametype of needle as employed in the internal radiation of carcinoma of theprostate, so that the needles employed for one may be employed forthe other purpose. The device constitutes a small fork which may beplunged into the tumor mass through the Brown-Beurger operatingcystoscope (Fig. 2 and Fig. 3), and the cystoscope fixed by the em-ployment of a mechanical hand. The mechanical hand already onthe market and pictured in Dr. Hugh Youngs article (Technique ofRadium Treatment of Cancer of the Prostate and Seminal Vesicles;Surgery, Gynecology and Obstetrics; January, 1922; page 93), beingmost satisfactory for the purpose.
