Objective: The objective of this study was to evaluate the uroflowmetry test results performed for normal and urgent desire to void and their correlation with International Prostate Symptom Score (IPSS) values in adult male patients having lower urinary tract symptoms (LUTS) complaints.

Material and methods: In this prospective study, a total of 83 patients were included. With a normal desire to void, maximum flowrate (Qmax)-normal, average flowrate (Qaverage)-normal, and void volume (VV)-normal values were obtained. Residual urine volume was examined by suprapubic ultrasound within 5 minutes following uroflowmetry, and  calculated. The maximum bladder volume (MBV)-normal value was calculated by adding the residual-normal volume and VV-normal values. The same procedures were repeated the next day with the sensation of urgency, Qmax-urgency, Qaverage-urgency, VV-urgency, residue-urgency,  MBV-urgency values were obtained.

Results: Statistically significant difference was determined for all parameters, and higher values were obtained in the urgency group for all parameters (p<0.05). A correlation analysis was performed for the Qmax-normal and Qmax-urgency values and the IPSS. Both parameters were not statistically significantly correlated with IPSS, but the correlation coefficient of Qmax-urgency was found to be higher than Qmax-normal (p=0.85, Correlation Coefficient=-0.022 for Qmax-normal and IPSS; and p=0.069, Correlation Coefficient=-0.214 for Qmax-urgency and IPSS, respectively).

Conclusion: Our study is the first study examining the effect of bladder sensitivity on uroflowmetry parameters in male patients having LUTS. More reliable results might be obtained in adult male patients with LUTS complaints when the uroflowmetry test is performed with a feeling of urgency to void. Our results need to be supported by more objective criteria, rather than subjective criteria such as IPSS.
