[The laser in urology].

The clinical application of laser in urology has become possible after intensive experimental work. Because of necessary facilities and high costs connected with, the use of laser can be recommended for high specialised medical institutions. At the present time only Neodym-YAG- and Argon-laser meet all the urologic requirements. The CO2-laser is restricted for broad application. Actually tumours of the bladder, urethra, and penis are the fields for laser-application. Treatment of urethral strictures with laser-irradiation seems to be successful too. The photosensitization could being break-through in treatment of superficial tumours.
