Area of Science:

  • Urology
  • Minimally Invasive Surgery
  • Medical Technology

Background:

  • Transurethral resection of the prostate (TURP) offers good long-term outcomes but involves significant intraoperative blood loss and TUR syndrome risks.
  • Minimally invasive alternatives are sought to mitigate the morbidity associated with traditional TURP.

Purpose of the Study:

  • To present an improved high-frequency technology designed to minimize bleeding during prostate tissue resection.
  • To enhance surgical outcomes by reducing the invasiveness of TURP.

Main Methods:

  • Modulation of output signals from commercial high-frequency generators to create efficient coagulation zones.
  • Development of a technique termed "coagulating intermittent cutting" for precise tissue resection.

Main Results:

  • Laboratory, in vitro, and clinical studies demonstrated excellent cutting characteristics with reduced bleeding.
  • Significant reduction in the need for blood transfusions and lower incidence of TUR syndrome.
  • Earlier indwelling catheter removal and decreased hospitalization duration were observed.

Conclusions:

  • Coagulating intermittent cutting, an advanced high-frequency technology, enables blood-sparing tissue resection.
  • This technique effectively reduces patient morbidity associated with prostate surgery.
