About this trial
This prospective observational study aims to investigate the relationship between anatomical parameters-specifically the distance from the anus to the needle insertion point and the depth required to reach the pudendal nerve-during neurostimulation-guided pudendal nerve block and patients' age, height, and weight in children undergoing penile surgery.

Disqualifiers
Patients with incomplete measurement data
Cases where successful nerve block cannot be performed or nerve stimulation is not detectable at currents ≥1.5 mA
Patients or parents/legal guardians who refuse pudendal nerve block
Patients with pelvic deformities or neuromuscular disorders
