| Abstrakt: |
By in vitro investigations with the laser set medilas 2 YAG (MBB) possible dosage insecurities were demonstrated in the radiation of urinary bladder cancers using Nd-YAG-laser light. While the endoscopic distance of e.g. 3 +/- 1 mm is accompanied by a relatively low dosage uncertainty of +/- 23%, the thermic formation of gas bubbles on the endoscopic end area, which is immersed in flush fluid, may be cause a dosage uncertainty of 80%. Help is possible by slipp off the endoscope area on the bladder wall. Uncertainties because of different tissue absorption of radiation are not taken into account. |
