Changes in urinary expression of chemokine and matrix proteins. (a) Urinary CXCR4 (40Â kDa) levels were significantly higher in stone patients before ESWL compared to controls. Following ESWL, CXCR4 levels significantly increased compared to pre-ESWL levels in stone patients and dropped below pre-ESWL level at 4 week (b) MMP2 (Matrix Metalloproteinases 2, 72Â kDa) showed no significant different in stone patients before ESWL compared to controls. MMP2 elevated significantly at 2 weeks following ESWL and returned to control level at four weeks. (c) MMP9 (Matrix Metalloproteinases 9, 92Â kDa) showed no significant different in stone patients before ESWL compared to controls. MMP2 elevated significantly at 2 weeks following ESWL and returned to control level at four weeks
