[Capacitive effects during transurethral resections with high-frequency currents (author's transl)].
The cutting probe of transurethral resection devices has to be fed through a line inside of the shaft. The capacitive high-frequency currents between this feeder and the shaft flow through the urethra and may cause destructive heat within the urethra if a metallic shaft is used. This paper shows that no danger is caused from these capacitive currents as long as the capacity between feeder and shaft is less than 120 pF.
