Abstract: | Introduction: We studied the effect of dutasteride on bone mineral density (BMD) in aging male patients with lower urinary tract symptoms (LUTS) and prostatic enlargement.Methods: We prospectively studied 17 patients with LUTS and prostatic enlargement. Before and 1 year after dutasteride (0.5?mg daily), we assessed International Prostate Symptom Score (IPSS), prostatic volume (PV), serum prostatic-specific antigen (PSA) and testosterone. BMD in the lumbar and femur was measured by DEXA method.Results: Dutasteride significantly reduced PV (from 51?±?24 to 34?±?17?ml, p?0.001) and improved IPSS (from 15.1?±?9.8 to 11.7?±?10.3, p?0.05). Serum PSA was significantly decreased (from 3.2?±?2.6 to 1.0?±?0.8?ng/ml, p?0.001), while serum testosterone “was not changed” significantly. BMD of the lumbar “was not changed” significantly after dutasteride. BMD of the femur was significantly improved (from 0.75?±?0.14 to 0.82?±?0.16?g/cm2, p?0.01). In nine patients whose testosterone was increased after dutasteride, BMD of the lumbar (from 1.18?±?0.26 to 1.22?±?0.25?g/cm2, p?0.05) and femur (from 0.76?±?0.12 to 0.84?±?0.16?g/cm2, p?0.05) was significantly improved.Conclusions: Dutasteride has a potential to improve BMD with elevation of serum testosterone in aging male patients with LUTS and prostatic enlargement. |
