“…The above authors also reported that sudden change of habitus cause severe psychological stress on the person and evacuation may not be complete in the new position. 24 Similar to various other reports [6][7][8][9]22 we also found that accustomed voiding position conferred highest flow rates. So it may be suggested that it is the natural voiding habitus and learned behavior of an individual, which influences the uroflowmetric parameters.…”

“…Riehmann et al 6 investigated the effect of voiding positions on uroflowmetry in healthy men and nursing home residents in standing and recumbent positions. They demonstrated a decrease in Q max without any effect on PVR in the recumbent position relative to standing in both nursing home residents and healthy men.…”

“…[5][6][7][8][9][10][11][12][13][14][15] Uroflow and PVR have been reported to be affected by voiding position in institutionalized elderly and patients of BPH and cause increased risk of bacteruria. The study was planned to evaluate the effect of posture on uroflow.…”

“…7 Riehmann and colleagues reported that standing is better than the recumbent position. 8 Yamanishi and colleagues compared uroflowmetry in standing, sitting, lateral, supine, prone positions in men between the ages of 24 and 40; they found the highest Qmax rate with the prone position. The Qmax rate decreased in the standing, sitting, supine and lateral positions.…”

Introduction:We assessed the effect of different voiding positions on uroflowmetric parameters and post-void residual (PVR) urine volume in symptomatic benign prostatic hyperplasia (BPH) patients. We also evaluated the effect of alpha blockers on PVR in different voiding positions. Methods:The study was performed with 110 BPH patients over 50 years old. In total, 4 uroflowmetries were performed in all patients: 2 patients in the sitting position and 2 in the standing position. PVR was measured with transabdominal ultrasonography. Also, patients were divided into two groups according to the alpha adrenergic blocker treatment; the effect of this treatment on their uroflowmetric parameters in different positions was evaluated. Results: Maximum flow rate (Qmax) and average flow rate (Qave) were significantly higher in patients in the sitting position, but there were no differences in other uroflowmetric parameters and PVR volume (Qmax: 15.5±5.9 mL/s vs. 13.7±5.2 mL/s, Qave: 11.4±4.6 mL/s vs. 10.7± 3.9 mL/s, respectively; p < 0.05). The Qmax and Qave were significantly higher in sitting position, compared to the standing position, in both alpha adrenergic treatment and non-treated groups; again, there were no differences in other uroflowmetric parameters and PVR volume. Conclusion: Qmax and Qave values were significantly higher in the sitting position. Alpha blockers did not affect any change.
