The correlation between preoperative renal scintigraphy and postoperative renal function in upper urinary tract urothelial carcinoma patients following radical nephroureterectomy

We developed an equation to predict postnephroureterectomy 1 year eGFR before surgery based on preoperative MAG3 renal scintigraphy results and preoperative eGFR. The equation could be more accurate in the situation if the diseased kidney is not hydronephrotic.
