In collaboration with the department of urology, LUMC.
Objective: To end the worldwide discussion on the optimal voiding posture for men.
Design: Systematic review and meta-analysis.
Methods: Studies comparing urodynamic parameters in standing versus sitting voiding position were eligible for inclusion. Potentially relevant articles were retrieved from fifteen electronic databases and through chain-referral sampling. Studies were stratified according to health status of included participants: healthy individuals and patients with Lower Urinary Tract Symptoms (LUTS).
Main outcome measures: Difference in maximum urinary flow rate (ml/s, Qmax), voiding time (sec, TQ) and post-void residual volume (ml, PVR). Standardized mean differences were pooled in a random effects model.
