Study design, materials and methods
A total of 388 patients who presented with LUTS in urology OPD were included in the final analysis. IPSS was calculated for all the patients and categorized into mild (0-7), moderate (8-19) and severe (20-35). Patients underwent uroflowmetry and voided volume, maximum flow rate and average flow rates were calculated and considered. Coefficient of correlation was calculated for maximum and average flow rate with respect to IPSS.
Interpretation of results
The correlation coefficient between average flow rate and IPSS scores was 0.632 which was significantly higher (p value <0.001) in comparison to correlation coefficient between Q-max and IPSS score (r -0.603).
