Summary
This trial is testing if using a skin patch to deliver oxybutynin is better than taking it by mouth for children after bladder surgery. The goal is to reduce pain and urgency with fewer side effects. The skin patch method is expected to be more effective because it avoids processing by the liver. Oxybutynin has been used to treat bladder dysfunction in both adults and children, with various formulations showing effectiveness but also significant side effects.
Who is the study for?
This trial is for children aged 4 to 8 who are about to have bladder surgery and will need a catheter afterwards. It's not for kids under 4, those with previous bladder surgeries, neurologic diseases affecting the bladder, or on certain meds like antispasmodics or CNS-affecting drugs.
What is being tested?
The study is testing if an Oxybutynin patch (applied to the skin) is better than oral Oxybutynin pills at reducing post-surgery bladder pain and urgency in young patients following their procedure.
What are the potential side effects?
Oxybutynin may cause dry mouth, constipation, dizziness, blurred vision, and difficulty urinating. The patch might also irritate the skin where it's applied.

Trial Design
2Treatment groups
Experimental Treatment
Active Control
Group I: Transdermal administrationExperimental Treatment1 Intervention
Guardian will be given the transdermal patch (3.9mg oxybutynin) at the preoperative appointment with instructions to apply the day prior to surgery. While in the hospital no oral oxybutynin will be prescribed.
Group II: Oral administrationActive Control1 Intervention
Oral oxybutynin (5mg) is administered in the preoperative area prior to surgery. The current regimen is to mix the oxybutynin with the standard preoperative Versed so children do not have to take two dosages.
Post-operatively oral oxybutynin (5mg) is administered every 8 hours in the hospital.

Side Effect Profile
Prior Approvals
Other Research
The most common treatments for Overactive Bladder (OAB) include anticholinergic medications and beta3-adrenoceptor agonists. Anticholinergics block muscarinic receptors in the bladder, reducing involuntary contractions and increasing bladder capacity.
Beta3-adrenoceptor agonists, such as mirabegron, relax bladder muscles by activating beta3 receptors, enhancing storage capacity. Transdermal administration, like oxybutynin patches, delivers medication through the skin, potentially minimizing systemic side effects such as dry mouth and constipation.
This method is beneficial for OAB patients who are sensitive to these side effects, improving treatment adherence and quality of life.
