Clinical Trial Summary

Comparison of the obturator nerve block in patients undergoing transurethral resection due to bladder tumor, technically using ultrasound guided or blinded with anatomical signs.

Description:

The primary aim of this study is to compare the success rates of ONB techniques performed with ultrasound guided or blind technique. Its secondary purpose is to compare the effect of peroperative bleeding and control cystoscopy performed in the postoperative 3rd month on the presence of recurrent tumor.

Intervention

Procedure:
• obturator nerve block
The ultrasound probe will be placed in the middle of the tuberculum pubis and femoral artery, 5-6 cm below the inguinal ligament, and 5 mL of 0.5% bupivacaine will be injected into the anterior and posterior branches of the ON with a needle. In the second group, after the patient is placed in the lithotomy position, 1.5 cm lateral tuberculum pubis and 1.5 cm caudal will be marked and needle entry will be made and 0.5% bupivacaine will be injected with 10 mL. The time elapsed until the first needle insertion and local anesthetic injection is completed will be recorded as the application time.
