Table 2 Changes in mean renal parenchymal width and glomerular filtration rate before and after indwelling ureteral stents. Mean length of stay in unilateral, isolated kidney and bilateral groups: 67.29 ± 4.47 months, 73.40 ± 60.35 months, 50.22 ± 29.65 months; all using paired t-test; PW renal parenchymal width, eGFR estimated glomerular filtration rate.
