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

Area of Science:

• Urology
• Surgical Technology
• Biomedical Engineering

Background:

• The urinary bladder is susceptible to damage from surgical procedures.
• Minimally invasive surgical techniques are continually being explored to improve patient outcomes.
• Plasma flow technology offers a novel approach for tissue ablation and modification.

Purpose of the Study:

• To evaluate the effects of plasma flow on the urinary bladder in both acute and chronic experimental settings.
• To compare the efficacy and healing response of plasma flow with CO2 laser treatment on bladder tissue.
• To assess the potential clinical applicability of plasma flow for bladder tissue removal.

Main Methods:

• Acute and chronic experiments were conducted on 15 mongrel dogs.
• Morphological studies were performed to assess bladder wall damage and healing.
• CO2 laser was used as a comparative ablation method.
• The Fakel-7 plasma surgical complex was utilized as the plasma flow device.

Main Results:

• Plasma flow demonstrated effectiveness in acute bladder tissue ablation.
• Chronic experiments showed wound healing completed by day 20 with thin connective tissue scar formation.
• Plasma flow induced a less inflammatory reaction in the initial 7 days compared to laser radiation.
• The Fakel-7 plasma surgical complex showed potential for operative removal of abnormal bladder wall tissues.

Conclusions:

• Plasma flow is a promising tool for urinary bladder surgery, offering efficient tissue removal.
• The healing process following plasma flow exposure is comparable to laser treatment, with reduced early inflammation.
• The Fakel-7 plasma surgical complex holds potential for clinical application in treating bladder wall abnormalities.
