Correlation between intravesical prostatic protrusion and maximum flow rate among Nigerian men with Benign Prostatic Hyperplasia

Objective: To determine the correlation between intravesical prostatic protrusion and maximum flow rate in benign prostatic hyperplasia among Nigerian men. Materials and Methods: A cross-sectional prospective study that included patients who presented to the Urology clinic of Jos University Teaching Hospital with clinical features of BPE. Each had IPSS, Qmax and IPP measured in addition to clinical evaluation. Statistical analysis was done using SPSS(R) version 20 (SPSS, IBM, Chicago, IL, USA). Appropriate test statistics were used with p-value < 0.05 considered as significant. Results: Eighty-seven patients aged 40 - 86 years were enrolled in the study period. The means of age, IPSS, Qmax, IPP and PV - were 64.6±10.2 years, 16.7±7.6, 8.2± 3.8 ml/s, 12.9±7.0 mm and 70.1±50.3 mis respectively. IPP correlated negatively with Qmax (r=-0.519, p=0.000). Conclusion: Intravesical prostatic protrusion measurement is non-invasive, easily accessible, reproducible and more cost effective. It showed a significant correlation with Qmax. Therefore, it is a valuable parameter - for evaluation of patients with BPH.
