[External application of neodymium-YAG-laser in urology (author's transl)]

Results from treatment of benign tumors have been excellent, in malignant tumors the result have been encouraging so far. Special advantages of using the laser is the non-contact bloodless treatment and the avoidance of strictures of the urethra and external orifice. The longer healing period after the intensive Irradiation of urethra and penis carcinoma, can be as long as nine weeks depending on the size of the defect.
