ABSTRACT
OBJECTIVE: To assess the role of transforming growth factor-β1 (TGF-β1) in congenital ureteropelvic junction obstruction at diagnosis and during postoperative follow-up. MATERIAL AND METHODS: We conducted a case-control study including 19 patients with a mean age of 6.7 years and 19 matched controls. All patients presented negative voiding cystourethrography, obstructive diuretic renogram and underwent dismembered pyeloplasty. Urinary TGF-β1 and other markers were measured pre-, intra- and postoperatively. RESULTS: The mean bladder urine TGF-β1 concentration in obstructed patients prior to pyeloplasty was higher than in controls (92.5 pg/mL ± 16.8 vs. 35.8 pg/mL ± 16.2; p = 0.0001). The mean renal pelvic urine TGF-β1 concentration in the hydronephrotic kidney was higher than in the preoperative bladder urine sample (122.3 pg/mL ± 43.9 vs. 92.5 pg/mL ± 16.8; p = 0.036). Postoperative mean TGF-β1 concentration was significantly lower than preoperative TGF-β1 (48.7 pg/mL ± 13.1 vs. 92.5 pg/mL ± 16.8; p = 0.0001). CONCLUSION: TGF-β1 is a cytokine leading to renal fibrosis. The measurement of urinary TGF-β1 could become a useful tool for the diagnosis of obstructive hydronephrosis and the evaluation of the parenchyma function status, pre and postoperatively.
