PREDICT-H: Improving prediction of complications after hypospadias surgery

PREDICT-H Study: Prospective Research on Essential Determinants Influencing Complication Trends in Hypospadias - a Landmark Prospective Multicenter Cohort Study Aimed at Improving Outcome Prediction in Hypospadias Surgery

Observational Sidra Medicine · NCT07017842

See if measurements of penis anatomy before surgery can predict which boys aged 1–12 will have complications after their first hypospadias repair.

What this trial studies

This is a prospective observational cohort that will record standardized preoperative anatomical measurements (urethral plate width and length, glans size, chordee severity, meatal position, and related features) in boys undergoing primary hypospadias repair. Surgeons will use a common measurement protocol and postoperative complications will be tracked during follow-up. Statistical modeling will be used to derive and validate an objective nomogram linking preoperative anatomy to complication risk. The goal is to create a reproducible risk tool to support individualized surgical planning and family counseling.

Who should consider this trial

Good fit: Boys aged 1 to 12 years with primary distal, midpenile, or proximal hypospadias who are scheduled for initial surgical repair and whose parent or guardian provides consent.

Not a fit: Patients with prior hypospadias or penile surgery, major associated genital anomalies (e.g., ambiguous genitalia, severe DSD), or those unable to complete follow-up are excluded and unlikely to benefit from the prediction tool.

Why it matters

Potential benefit: If successful, the nomogram could help surgeons tailor surgical approaches and give families clearer, individualized information about risk of complications.

How similar studies have performed: Previous retrospective studies and meta-analyses have identified candidate anatomical risk factors, but large prospective multicenter validation of an objective prediction nomogram is limited.
