Interventional treatment: Diode laser

Show Summary Details

Preview

• Due to considerable optical penetration depth at 800 to 1100 nm, diode lasers and lasers near the Nd:YAG wavelengths of 1064nm, produce profound tissue coagulation of up to 10 mm, which increases with increased power (W) • Due to profound tissue coagulation depth at 800–1100 nm diode lasers are not suitable to treat larger prostates since the tissue ablation effect decreases with time and the side effects such as sloughing, incontinence and reoperation rates increase significantly • At certain wavelengths such as 1300–1500 nm, enucleation and bladder neck incision are feasible with diode lasers • Current data are inadequate for assessment and for recommendation of diode lasers in the clinical routine. Modulating the pulsing rhythm only seems to be not the suitable option to overcome the wavelength-based disadvantages (deep optical penetration depth).
