Challenges and outcomes in pediatric and adult kidney transplantation.

The preoperative evaluation and postoperative management of kidney transplantation are fundamentally tailored to the distinct needs of adult and pediatric populations. The pediatric assessment prioritizes growth, congenital anomalies (like CAKUT), neurodevelopmental progress, and achieving pre-emptive transplantation. In contrast, adult evaluation focuses on comprehensive cardiovascular screening, malignancy risk, and managing accumulated comorbidities, with a growing emphasis on frailty assessment. Surgical technique in children is adapted for size, requiring meticulous microvascular anastomosis and specific urinary reconstruction strategies, especially in the context of complex urological histories. Postoperatively, complication profiles differ adults face higher rates of delayed graft function and cardio metabolic sequelae, while children's unique vascular technical risks and the critical challenge of adolescent non-adherence prevail in children. For both groups of patients, urinary tract infections are a major concern, necessitating structured prophylaxis and management. Looking ahead, pediatric transplantation is exploring minimally invasive robotic techniques. Ultimately, successful long-term outcomes depend on a multidisciplinary, life-stage-specific approach that balances immunological risks with the distinct developmental or chronic disease trajectories of each patient to optimize graft survival and quality of life.
