Summary
This study introduces coagulating intermittent cutting, an improved high-frequency technology for prostate surgery. This method significantly reduces blood loss and complications, leading to shorter hospital stays and earlier catheter removal.
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.
