Linear ultrasound probe and the sacral hiatus at the sacral cornu level was visualized using an out-of-plane transverse view at 5-10 megahertz . The linear probe was then rotated 90 degrees and placed longitudinally in the midline to evaluate the sacral cornus, sacrococcygeal ligament and sacral bone.

Ultrasound (US) guided dorsal penile nerve block with in plane technique was done. Half of the total 0.2 ml/kg dose of 0.25% bupivacaine was administered while observing its distribution with US. The same procedure was then repeated on the other side of the penis.

A 22 Gauge 50 mm insulated needle was then introduced in the anterior-posterior direction at the middle of the ultrasound probe's superior edge with an out-of-plane approach and using an inclination of 15° in the sagittal plane. The needle tip's position was identified by direct visualization using the movement of adjacent anatomical structures.

It was assessed six times after the operation with Children's Hospital Eastern Ontario Pain Scale. The lowest scale score is 4 points and the highest 13 points. Significant pain behavior for Children's Hospital Eastern Ontario Pain Scale has been identified as 7 points or more. Following transfer from the recovery unit to the ward, the 1st, 2nd, 6th, 12th and 24th hour pain levels were evaluated by the ward nurse. Paracetamol was administered IV at a dose of 10 mg/kg if the scale score was 7 or higher.
