B. Djavan et al., Transurethral radiofrequency therapy for benign prostatic hyperplasia using a novel saline-liquid conductor: The virtual electrode, UROLOGY, 55(1), 2000, pp. 13-16
Radiofrequency (RF) energy has been introduced as a promising energy source
for treatment of benign and malignant tumors in animal models, as well as
in humans.(1-3) In urology, minimally invasive heat-based treatment options
, including microwave and RF energy, have been used to treat benign prostat
ic hyperplasia (BPH) with much enthusiasm. The clinical utility of microwav
e-based treatments has been reviewed elsewhere.(4) This update focusses on
the physics, applicability, and advantages of a novel saline-liquid conduct
or electrode for delivery of heat-based therapy to prostatic tissue. In con
trast with other heat-based treatment modalities, such as microwave (dielec
tric beating) and high-intensity focused ultrasound (mechanical distortion)
, RF energy generates interstitial heat by inducing translational molecular
motion.
