Comparison of Obturator Nerve Block With Ultrasound Guidance and Anatomical Signs

Comparison of Obturator Nerve Block With Ultrasound Guidance and Anatomical Signs in Patients Undergoing Transurethral Resection

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

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.

Inclusion Criteria:

• ASA I-II patients

Exclusion Criteria:

• Tumors that disrupt the integrity of the bladder,
• bladder floor tumors,
• coagulation disorders,
• motor in the lower limbs
• with sensory disturbances,
• uncooperative patients,
