About

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

Full 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.

116 participants in 2 patient groups

Ultrasound-guided obturator nerve block group

Active Comparator group

Description:

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.

Treatment:

Procedure: obturator nerve block

obtutaror nerve block with anatomical landmarks

Active Comparator group

Description:

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.

Treatment:

Procedure: obturator nerve block
