Morphological fundamentals in the treatment of tumors with the neodymium-YAG laser.
On the basis of experimental animal research regarding type, distribution, and depth of necrosis in urinary bladder under neodymium-YAG (Nd:YAG) laser irradiation, identical results have been confirmed in human tissue. Bladder tumors indicated for cystectomy have first been treated with the Nd:YAG laser and histologically examined. Destruction of tumor tissue is demonstrated. Particular attention was paid to the temporary closing of the lymphatic drainage system due to the deep coagulation capability of the Nd:YAG laser irradiation. Nd:YAG laser irradiation is especially suitable for tumor coagulation, since simultaneous interception of lymphatic drainage will inhibit the spreading of tumor cells.
