Prophylactic Antibiotics for Hypospadias
(PROPHY Trial)
What You Need to Know Before You Apply
What is the purpose of this trial?
The trial aims to determine if preventive antibiotics after surgery for mid-to-distal hypospadias (a condition where the urethra's opening is not at the tip of the penis) are beneficial. Participants will receive either a placebo (a harmless pill with no active drug) or trimethoprim-sulfamethoxazole (an antibiotic) to assess any differences. Individuals who have undergone a single-stage repair for this type of hypospadias and meet specific criteria, such as having a urethral repair of 20 mm or less, may qualify to participate. As an unphased trial, this study provides participants the chance to contribute to significant research that could enhance post-surgical care for future patients.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop all current medications, but you cannot use antibiotics within seven days before the hypospadias repair or take oral antibiotics other than the study medication during the trial.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that the antibiotic trimethoprim-sulfamethoxazole, tested in this trial, has been used safely in past studies. In these studies, patients taking this antibiotic experienced fewer cases of pus in their urine, a sign of infection, compared to those who did not take it. This suggests the antibiotic is effective and generally well-tolerated.
Furthermore, trimethoprim-sulfamethoxazole is widely used for various conditions, enhancing its safety profile. No serious side effects were reported in these studies, indicating that the treatment is generally safe.12345Why are researchers excited about this trial?
Trimethoprim-sulfamethoxazole is unique because it combines two antibiotics to prevent infections following hypospadias surgery. Unlike the standard practice, which might not routinely use prophylactic antibiotics post-surgery, this treatment aims to reduce infection risk with a specific dosage regimen over just 10 days. Researchers are excited about this approach because it could offer a targeted, efficient way to protect against infections, potentially improving recovery outcomes for patients.
What evidence suggests that this trial's treatments could be effective for hypospadias?
This trial will compare the effects of trimethoprim-sulfamethoxazole with a placebo in preventing urinary tract infections after hypospadias surgery. Research has shown that the antibiotic trimethoprim-sulfamethoxazole might help lower the risk of such infections. In one study, patients who took this antibiotic had less pus in their urine, indicating reduced infection. However, another study found no significant reduction in infection rates or complications after surgery compared to a placebo. This mixed evidence suggests that while there may be some benefits, the treatment's effectiveness remains uncertain.12367

Are You a Good Fit for This Trial?
This trial is for boys with mid-to-distal shaft hypospadias who are getting a single-stage repair and an open-drainage urethral stent for 5-10 days. It's not for those who've had previous repairs, have allergies to trimethoprim-sulfamethoxazole, take conflicting meds, or have conditions like HIV/AIDS that increase infection risk.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- Placebo
- Trimethoprim-sulfamethoxazole
Trial Overview
The study is testing if giving preventive antibiotics (trimethoprim-sulfamethoxazole) after hypospadias surgery helps more than a placebo. Boys will be randomly given either the antibiotic or placebo to see which works better at preventing complications.
