Ultrasound-guided reversed dorsal penile nerve block versus standard dorsal penile nerve block for pediatric circumcision
Official title: A Comparison of Reversed-Ultrasound-Guided Dorsal Penile Nerve Block (RUS-DPBP) and DPNB in Circumcisions for Pediatric Patients
Run by Centre Hospitalier Universitaire Vaudois · NCT06706375 · Data updated 2026-11-12
This trial will test whether an ultrasound-guided reversed dorsal penile nerve block gives better pain control and reduces opioid use compared with the standard landmark-based block in boys having circumcision.

Is this trial a fit for you?
✓Likely a good fit
Male patients under 18 scheduled for circumcision who can provide informed consent via a parent or guardian and who have no contraindication to local anesthesia or allergy to bupivacaine are eligible.
✕Probably not a fit
Patients with contraindications to local anesthesia, allergy to bupivacaine, chronic opioid treatment, or those having additional simultaneous surgeries are unlikely to benefit from this comparison.

What this trial studies
This interventional trial compares an ultrasound-guided reversed dorsal penile nerve block (RUSDPNB) with the standard landmark-based dorsal penile nerve block (DPNB) in males younger than 18 undergoing circumcision. Participants receive general anesthesia plus one of the two nerve block techniques before surgery. Investigators will record intraoperative and postoperative opioid consumption, pain scores in the immediate postoperative period, and local complications such as hematoma or injection-related injury. The goal is to determine whether ultrasound guidance improves analgesia and lowers opioid requirements and complication rates versus the traditional technique.
Why it matters
Potential benefit: If successful, the ultrasound-guided approach could reduce postoperative pain, lower opioid use, and decrease injection-related complications for boys undergoing circumcision.
How similar studies have gone: Prior pediatric studies of ultrasound-guided penile blocks have reported improved pain control and fewer local complications in some reports, but results across studies have been mixed and not uniformly conclusive.
