Renal outcomes of patients according to asymptomatic pyuria. There was no significant difference between group A and group B in initial eGFR (92.5 ± 27.1 vs. 88.7 ± 32.5 ml/min/1.73m²; P=0.35). However, the final eGFR was significantly lower in group B than in group A (63.3 ± 37.0 vs. 85.5 ± 31.7 ml/min/1.73m²; P<0.001). Moreover, ΔeGFR was larger in group B than in group A (-2.7 ± 4.56 vs. -1.17 ± 5.8 ml/min/1.73m² per year, respectively; P=0.01). The incidence of ESRD was also significantly higher in group B than in group A (n = 15, 16.0% vs. n=7, 4.3%; P=0.001). eGFR, estimated glomerular filtration rate; ESRD, end-stage renal disease.
