Transurethral partial cystectomy with continuous wave laser for bladder carcinoma.

Area of Science:

• Urology
• Surgical Oncology
• Laser Technology

Background:

• Bladder carcinoma presents a significant oncological challenge.
• Current treatment modalities for bladder cancer have limitations.
• Precise surgical techniques are crucial for effective tumor removal and patient outcomes.

Purpose of the Study:

• To introduce and evaluate a new technique for bladder carcinoma treatment using a 2-micrometer continuous wave laser.
• To assess the feasibility of vaporizing and incising the full-thickness bladder wall and peeling muscular layers with the laser.
• To determine the efficacy and safety of this laser-based partial cystectomy.

Main Methods:

• Nine patients with bladder carcinoma underwent transurethral treatment with a 2-micrometer laser under sacral block.
• The laser was utilized to incise the full-thickness bladder wall around tumors and peel the detrusor muscle layers.
• Tumor specimens were pathologically examined, and patients were monitored for complications and recurrence.

Main Results:

• All nine operations were successfully completed with an average operative time of 8.7 minutes.
• Minimal blood loss and no intraoperative hemorrhage or obturator nerve reflection were observed.
• Postoperative follow-up (6-9 months) revealed no recurrence at the resection site, although one case of bladder perforation occurred.

Conclusions:

• This study reports the first use of a 2-micrometer laser for bladder carcinoma treatment.
• The technique allows for precise vaporization and incision of the full-thickness bladder wall, facilitating partial cystectomy.
• The 2-micrometer laser offers a promising minimally invasive option for select bladder cancer cases.
