NCT ID NCT04142632
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study followed 10 males who had surgery for hypospadias (a birth defect where the urine opening is on the underside of the penis) to see how they fared long after puberty. Researchers performed physical exams, bladder and testicle ultrasounds, and blood tests to check for complications, urinary symptoms, and sexual function. The goal is to learn whether common surgical techniques hold up over time.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this could help doctors understand how well different hypospadias surgeries work long-term, guiding better treatment choices for future patients.
- What could go wrong
- This is a very small study (10 people) that only observes outcomes—it does not test a new treatment. Results may not apply to everyone with hypospadias.
