[A histological and ultrastructural study of the effects of the argon laser scalpel on the kidney].
The authors carried an histological and ultrastructural study on rat kidney following polar excision by argon laser. The involvement of the remainder portion of the kidney was evaluated analysing the depth of the damage induced by the laser radiation. Restitution ad integrum was found below 360 micron thickness with a different involvement of the various kidney components. Glomeruli showed a deep damage caused by intravascular photocoagulation. On the contrary, tubular and extracellular damage was less serious and the damaged area extended for only 240 micron from the section, probably for a lack of absorbance of the argon radiation by clear and water-rich tissues.
