Deceased Kidney Donation Interpretation
While the 103,000 people waiting for a kidney transplant represent a staggering demand, the sobering reality is that our supply, pieced together from a consenting fraction of the population, is an impressively engineered but insufficient mosaic of standard, extended, perfused, and paired donations that still sees seventeen people die each day.

Living Kidney Donation Interpretation

Transplant Outcomes Interpretation
While kidney transplantation offers a profound second chance—with pediatric patients thriving at near-universal survival rates and living donors providing gifts that can last over two decades—the journey remains a high-stakes balance sheet where immunosuppression adherence, long-term graft attrition, and disparities in outcomes remind us that even a 96% success story still demands a vigilant, lifelong partnership between medicine and the patient.
