  1. The Shapiro–Wilk normality test was used to investigate the normal distribution of continuous variables. Continuous and normally distributed variables are presented as mean ± standard deviations.
  2. eGFR is expressed in mL/min/1.73 m2.
  3. eGFR estimated glomerular filtration rate, SU segmental ureterectomy, RNU radical nephroureterectomy.
  4. aVersus preoperative eGFR.
  5. bPostoperative eGFR values at 12 months were available for 34 (85%) patients who underwent SU.
