Summary
Surgeon experience and proximal meatal position increase hypospadias repair complications. The complication rate decreases with experience, stabilizing after 50-75 tubularized incised plate urethroplasty (TIPU) cases.
Area of Science:
- Pediatric Urology
- Surgical Outcomes
- Hypospadias Repair
Background:
- Hypospadias repair is a common pediatric urology procedure.
- The tubularized incised plate urethroplasty (TIPU) is a widely used technique.
- Factors influencing TIPU success require further investigation.
Purpose of the Study:
- To evaluate the impact of surgeon experience and clinical factors on primary hypospadias repair outcomes using TIPU.
- To identify predictors of complications in pediatric hypospadias surgery.
Main Methods:
- Retrospective review of pediatric primary hypospadias repairs using TIPU.
- Analysis of complication rates based on patient age, stent use, meatal position, and surgeon experience.
- Multivariable logistic regression and non-linear modeling to assess influencing factors and learning curve.
Main Results:
- A total of 303 pediatric patients were included, with a median age of 1.4 years.
- The overall complication rate was 31.7% (133 complications in 96 patients).
- Proximal meatal position was the only significant factor increasing complication rates; a learning curve was observed, with decreasing complication rates over time.
Conclusions:
- Proximal meatal position significantly increases complication rates in TIPU hypospadias repair.
- Surgeon proficiency improves, with complication rates stabilizing after approximately 50-75 cases.
- TIPU is an effective technique, but careful patient selection and surgical experience are crucial for optimal outcomes.
