[The Fakel-7 plasma surgical unit in operations on the bladder (experimental research)]

The study was undertaken to examine the effect of plasma flow on the urinary bladder of 15 mongrel dogs in acute and chronic experiments. The acute experiment defined the power of plasma flow in operations on the bladder. Morphological studies comparatively assessed the bladder wall damaged with a CO2 laser. The chronic experiment examined morphological changes in a bladder wound 1-30 days following exposure to plasma flow. The processes of healing of the urinary bladder wound were found to end in formation of a thin connective tissue scar on day 20, as with laser radiation, and be followed by a far less inflammatory reaction within the first 7 days. The application of a Fakel-7 plasma surgical complex as a destructor was admitted to be promising in operatively removing the abnormally changed tissues of the bladder wall in the clinical setting.
