Application of lasers in bladder cancer

Area of Science:

• Urology
• Oncology
• Laser Medicine

Background:

• Endoscopic tumor destruction is crucial for bladder cancer management.
• Transurethral resection (TUR) has limitations, including higher local recurrence rates.
• Minimally invasive techniques are sought to improve treatment efficacy and reduce morbidity.

Purpose of the Study:

• To evaluate the efficacy of Neodymium-doped Yttrium Aluminum Garnet (Nd:YAG) laser in endoscopic bladder tumor destruction.
• To compare the local relapse rate of Nd:YAG laser treatment with Transurethral Resection (TUR).
• To assess the impact of Nd:YAG laser therapy on reducing the rate of cystectomy.

Main Methods:

• Endoscopic application of Nd:YAG laser for bladder tumor ablation.
• Induction of homogeneous necroses with simultaneous vascular occlusion.
• Combination therapy with or without pelvic lymphadenectomy.

Main Results:

• Nd:YAG laser enables precise tumor destruction under excellent visualization.
• Achieved homogeneous necrosis with effective occlusion of blood and lymphatic vessels.
• Demonstrated a remarkably low local relapse rate compared to TUR.
• Significantly reduced the rate of cystectomy in recent years through combined treatment approaches.

Conclusions:

• Nd:YAG laser therapy is a highly effective endoscopic treatment for bladder tumors.
• The technique offers superior local control and reduces the need for radical surgery.
• Nd:YAG laser application presents a valuable alternative for bladder cancer management.
