Objective: The purpose of this study was to investigate the relationship between the prostatic urethral angle (PUA) and the peak urinary flow rate (Qmax), as well as the severity of lower urinary tract symptoms (LUTS) in men with benign prostate hyperplasia. Materials and methods: The records of first-visit male patients with LUTS in the outpatient department of our institution were obtained. A transrectal ultrasound was performed on these patients after a detailed physical examination and medical history taking were performed. The International Prostate Symptom Score (IPSS) of the patients, the prostate size, the length of intravesical prostatic protrusion (IPP), and the PUA were evaluated. The patients also underwent uroflowmetry and bladder scan for residual urine. Results: A total of 227 patients were included in this study. The mean PUA was 44.58 ± 12.87°. The mean prostate volume was 39.39 ± 19.79 mL, and the mean IPP was 4.82 ± 6.82 mm. After utilizing multivariate linear regression analysis, PUA was independently associated with IPSS (p < 0.001) and Qmax (p < 0.001). However, prostate volume and IPP were not associated with the above clinical items. None of the prostatic parameters were associated with the amount of postvoiding residual urine. Conclusion: PUA has a remarkable correlation with Qmax and IPSS in men with LUTS. As PUA increased, IPSS also increased, and urinary flow rate decreased, exhibiting an inverse relationship.
