Increased Plasma Ignition Distance Practice may Prevent the Obturator Reflex Occurrences and Compare of its...

Area of Science:

• Urology
• Surgical Techniques
• Anesthesiology

Background:

• Obturator nerve reflex (ONR) is a common complication during bipolar transurethral resection of the bladder (B-TURB).
• Effective inhibition of ONR is crucial for successful B-TURB, particularly for tumors located on the lateral bladder wall.

Purpose of the Study:

• To compare the efficacy of obturator nerve block (ONB) and increased plasma ignition distance practice (IPDP) in inhibiting ONR during B-TURB.
• To evaluate the impact of these techniques on surgical outcomes, including tumor resection and patient safety.

Main Methods:

• A randomized study of 60 patients with bladder tumors requiring B-TURB.
• Patients were assigned to either ONB or IPIDP groups.
• ONR severity was graded, and primary endpoints included ONR occurrence and surgical completion; secondary endpoints were bleeding and perforation.

Main Results:

• A significant difference in ONR occurrence was observed between the ONB and IPIDP groups (P = 0.0011).
• No significant difference was found in tumor resection success or surgical completion rates between the groups (P = 0.764).
• No correlation was identified between ONR severity and tumor size (P = 0.478).

Conclusions:

• Both ONB and IPIDP demonstrate comparable effectiveness in achieving successful B-TURB.
• IPIDP presents potential advantages over ONB, including reduced operative time, lower costs, and less stringent personnel training requirements.
