  • Title: Urinary transforming growth factor-beta1 levels correlate with bladder outlet obstruction.
    Author: Monga M, Gabal-Shehab LL, Stein P.
    Journal: Int J Urol; 2001 Sep; 8(9):487-9. PubMed ID: 11683968.
    Abstract:
    BACKGROUND: Urinary transforming growth factor-beta1 (TGF-beta1) levels have been shown to correlate with elevated intrapelvic pressure associated with ureteropelvic junction obstruction. Other studies have evaluated urinary TGF-beta1 levels in prostate cancer. This study tests the hypothesis that urinary TGF-beta1 levels might correlate with objective measures of bladder outlet obstruction (BOO). METHODS: Twenty-three men (age: 46-85 years) with lower urinary tract symptoms underwent urodynamic studies consisting of non-invasive uroflowmetry, cystometrogram and voiding pressure flow studies. Patients were classified as obstructed (n = 17) or not obstructed (n = 6) based on Abrams-Griffith nomograms. Urinary TGF-beta1 was extracted from an aliquot of urine obtained at the time of bladder catheterization for urodynamic studies. Urinary TGF-beta1 levels were then determined by enzyme-linked immunosorbent assay (ELISA). RESULTS: There was a strong correlation between urinary TGF-beta1 levels and the presence of obstruction by Abrams-Griffith nomogram criteria (P = 0.025). Urinary TGF-beta1 levels were significantly higher in men with obstruction (0.039 +/- 0.011 pg/mL) than in men without obstruction (0.029 +/- 0.009 pg/mL; P = 0.036). CONCLUSION: Urinary TGF-beta1 levels correlate with objective measures of BOO. Further study is needed to test the utility of urinary TGF-beta1 as a non-invasive diagnostic tool for BOO.
