Abstract Objective: The prevalence of benign prostatic hyperplasia (BPH) rapidly increases after the 4th decade of life. The combination of tamsulosin and dutasteride is a well established therapy for BPH of≥40 g. Non-invasive urodynamic parameters can predict the outcome of medical therapy in patients with BPH. We aimed to correlate these parameters with treatment responses in BPH patients under medical management. Methods: A prospective study was conducted in the Department of Urology in our hospital from May 2014 to April 2015. A total of 100 patients with BPH≥40 g who fulfilled our inclusion criteria were included. Treatment responses were determined by the International Prostate Symptom Score (IPSS) and uroflowmetry. Transabdominal ultrasonography with Doppler was performed to measure prostate volume, intravesical prostatic protrusion (IPP), detrusor wall thickness (DWT), the prostatic capsular artery resistive index (RI) and prostatic urethral angle (PUA) before and 3 months after combination therapy of tamsulosin and dutasteride. Treatment responses were correlated with non-invasive urodynamic parameters. Results: The IPSS, uroflow, age, prostate volume, RI, IPP, DWT and PUA were correlated before and after treatment. Of the 100 patients, 70 (70%) showed significant improvement and 30 (30%) showed no improvement with therapy. Conclusion: Ultrasound bladder parameters are useful tools for measuring the treatment response in BPH patients. Our study shows that RI and DWT significantly correlate with the treatment response in BPH patients. More importantly, pretreatment values of increased IPP and PUA determines the non-improvement of symptoms in BPH patients. Our study suggests the importance of transabdominal ultrasonography (KUB-P) with Doppler for evaluating treatment responses to medical management.
