- Abstract
Introduction: To evaluate the effect of voiding positions on voiding parameters in healthy adult men. Methods: A total of 55 men without lower urinary tract symptoms were included in the study. Each participant was asked to void into a digital weight transduction uroflowmeter in each of the three voiding positions, standing, sitting and squatting, 2 times in each position. Each act of voiding was performed once the bladder was comfortably full to normal desire. Postvoid residue was measured after each void using ultrasonography. Maximal flow rate (Qmax), average flow rate Qave), voided volume (V), voiding time (Tv100) and time to Qmax (TQmax) were recorded and compared. Results: mean age of the participants was 26.58±7.04yrs and body mass index 21.66±3.09kg/m2. Qmax correlated positively with voided volume and negatively with age. Qmax and Qave were significantly lower and Tv100 & TQmax higher in sitting position compared to the other two positions. These were not different between standing and squatting positions. There was no significant difference in voided volume and postvoid residue in any of the positions. Conclusions: flow rates are significantly lower and voiding time significantly prolonged in sitting position compared to standing/squatting positions. Standing and squatting positions are similar regards to voiding characteristics. These observations emphasize the role of correct positioning and careful interpretation of urodynamic voiding results in various positions.
