Effect
|
|
1) Transurethral (TU) endoscopic beam from a "bare" fibre. TU endoscopic beam KTP or Holmium laser |
Deep coagulation + some vaporisation. Vaporisation + some coagulation. |
| 2) TU endoscopic fibre with a specialised "tip". | Superficial vaporissation or cutting. Some coagulation. |
| 3) Interstitial application of laser energy endoscopically or percutaneously using a "bare" or modified fibre. | Deep localised coagulation with variable immediate tissue disruption (minimal with diffusor tips, more marked with bare fibres). |
|
4) TU endoscopic fibre with various beam deflecting devices. a) TU balloons in combination with deflector. b) Low power density (PD) c) High PD Narrow beam, 60-80W, Contact or near contact. e.g. Nd-YAG of Holmium laser. |
Deep coagulatoins with minimal immediate tissue disruption. Deep coagulation and some immediate tissue disruption. Variable degree of tissue disruption, some vaporisation with underlying coagulation. |
