Ureteral replacement with appendix in pediatric renal transplantation

Area of Science:

• Urology
• Pediatric Surgery
• Radiation Oncology

Background:

• Ureteral necrosis is an infrequent yet significant complication after radiation therapy (RT), potentially compromising patient outcomes.
• Preservation of the native ureter is generally preferred, but ureteral substitution becomes necessary when graft function is at risk.
• Limited literature exists regarding appendiceal use for left ureteral replacement in pediatric cases.

Observation:

• This report details two pediatric cases where the appendix was utilized for left ureteral substitution.
• The study focuses on evaluating the functional evolution of the appendiceal graft in these patients.

Findings:

• The appendix served as a viable conduit for left ureteral replacement in the presented pediatric cases.
• Assessment of graft function over time is crucial for understanding long-term outcomes.

Implications:

• Appendiceal ureteral substitution presents a potential solution for managing ureteral necrosis in children post-RT.
• Further research is warranted to establish the efficacy and long-term safety of this technique in pediatric urology.
