Study population: Male patients aged 1 to 12 years with diagnosed distal, midpenile, or proximal hypospadias scheduled for primary surgical repair will be enrolled. Exclusion criteria include prior hypospadias or penile surgery, major genital anomalies (e.g., ambiguous genitalia, severe DSD), inability or refusal to consent, or incomplete follow-up. Patients will be recruited from multiple tertiary pediatric urology centers. Informed consent will be obtained from parents or legal guardians. All participants will be followed for a minimum of 6 months postoperatively to assess surgical outcomes and complications.

Brief summary: Hypospadias is a common congenital anomaly with complex anatomy that influences surgical outcomes. Despite numerous surgical techniques, a lack of standardized preoperative assessment protocols and consensus on anatomical risk factors limits prediction of complications. This study aims to systematically evaluate key anatomical features identified in previous meta-analyses-such as urethral plate width and length, glans size, chordee severity, meatal position, and others-in a large, prospective multicenter cohort. The ultimate goal is to develop and validate an objective nomogram predicting the risk of postoperative complications, enabling individualized surgical planning and improved patient counseling.
