In this article, the influence of body position during micturition on maximum urinary flow rate (Qmax), voiding time (TQ) and post-void residual volume (PVR) in healthy males and patients with LUTS is analyzed by means of a systematic review and meta-analysis.\\n\\nEVIDENCE ACQUISITION: A systematic search was conducted in 14 medical databases. Studies comparing urodynamic parameters in standing versus sitting position were eligible for inclusion. Studies were stratified according to health status of included male participants: healthy individuals and patients with LUTS. Standardized mean differences for Qmax, TQ and PVR were pooled in a random effects model.\\n\\nRESULTS: Eleven articles were included. In men with LUTS, a significantly lower PVR (-24.96 ml; 95%CI -48.70 to -1.23) was shown in sitting position compared to standing. In accordance, Qmax was increased (1.23 ml/s; 95%CI -1.02 to 3.48), and TQ was decreased (-0.62 s; 95%CI -1.66 to 0.42) in sitting position, although these differences did not reach statistical significance. In healthy men, Qmax (0.18 ml/s; 95% CI -1.67 to 2.02), TQ (0.49 s; 95%CI -3.30 to 4.27) and PVR (0.43 ml; 95%CI -0.79 to 1,65) were similar in sitting and standing position.\\n\\nCONCLUSION: For healthy men, no difference is found in any of the urodynamic parameters.
