Effcacy and safety of ND:YAG laser energy in the treatment of non-muscle-invasive bladder cancer of diffcult-to-access localization: A case report

Background . Bladder cancer is the 10th most common cancer worldwide and the most common malignancy of the urinary tract. Non-muscle invasive bladder cancer accounts for approximately 80 % of cases. Tumors localized in the anterior bladder wall may be challenging to resect completely due to diffcult visual access. Here we present a case of non-muscle invasive bladder cancer localized in a diffcult-to-access area. Case report . A 67-year-old patient with a mass on the anterior wall of the bladder underwent Nd:YAG laser ablation of non-muscle-invasive bladder cancer of diffcult localization in the urological hospital of the Russian Railways-Medicine Central Clinical Hospital. The previous histological examination of the biopsy specimen of the bladder mass reveled bladder cancer. The superfcial tumor growth was confrmed by preoperative MRI fndings. The Nd:YAG laser with a wavelength of 1064 nm, a power of 40 W and an energy density of 100 J/cm 2 was used. The laser beam was delivered through a side fre light guide. After surgery, a two-way catheter was inserted into the bladder for 12 hours. No intraoperative and postoperative complications were detected. Endoscopic evaluation of the effectiveness of the surgical stage was carried out at intervals of 3, 6 and 12 months from the date of surgery. Control cystoscopy revealed no cancer recurrence. Conclusion . Our clinical case demonstrated the high effcacy and safety of Nd:YAG laser ablation in the treatment of a patient with non-invasive bladder cancer located on the anterior wall of the bladder.
