The effect of bladder sensation on uroflowmetry parameters in healthy young men.

AIMS: To investigate the effect of the bladder sensation grade on uroflowmetry parameters.

METHODS: Fifty healthy volunteering young men were enrolled in the present study. In total, three uroflowmetry evaluations were made. Qmax , Qave , VV, and PVR urine was obtained three times in three described bladder sensation grades, nearly at the same time of the day.

RESULTS: The mean age of the participants in the present study is 29.08 ± 3.8 years. The mean Qmax values of the volunteers were 17.4 ± 4.8 ml/s, 24.1 ± 6.0 ml/s, and 29.6 ± 6.5 ml/s in the first, second, and third, voiding desire grades, respectively. The mean Qave values were 9.9 ± 2.1 ml/s, 12.9 ± 2.9 ml/s, and 15.9 ± 4.0 ml/s for each of the voiding desire grades mentioned. A statistically significant difference was obvious for all three bladder sensation grades in terms of Qmax and Qave values (P = 0.000). However, no statistically significant difference was seen regarding the PVR urine volumes. The mean voided volume in the first, second and third uroflowmetry were 140 ± 42 ml, 245 ± 64 ml, and 449 ± 105 ml, respectively. The highest Qmax and Qave values were obtained when the desire to void was urgent.

CONCLUSIONS: The findings of the study show that, uroflowmetry evaluations are to be made if the patients have a strong desire to void. Only thus the highest Qmax values can be obtained; yet, the degree of perceived bladder sensation does not have a statistically significant impact on PVR quantity. Neurourol.
