Implementation of a pediatric kidney transplantation program in Uzbekistan: Feasibility and early outcomes

Figure 2 Trends in kidney function markers and urine output before and during the first postoperative week. A: Median serum creatinine and urea levels on postoperative days 1, 3, 5, and 7. Both markers demonstrated a progressive decline, reflecting early recovery of graft function; B: Median daily urine output over the same period. Urine output peaked on day 3, consistent with the expected polyuric phase, and gradually decreased by day 7 while remaining above the normal range.
