NIBED pilotRandomized, Controlled, Cross-over, First-in-man Safety and Efficacy Trial of a Novel Non-invasive Bladder Emptying Device: The NIBED Study

The non-invasive bladder emptying device (NIBED) is a handheld medical device that is applied to the penis during urinating to aid bladder emptying in urinary retention patients with increased residual urine volume. This pilot study primarily seeks to determine the safety of the NIBED. Secondary objectives are to assess the efficacy of the NIBED, which is defined as the ability of the medical device to aid or improve bladder emptying, i.e. leads to less residual urine compared to not using the NIBED. During the intervention, the study participant will urinate with and without the NIBED. Safety variables such as penile pain, penile lesions and hematuria will be recorded. Efficacy will be assessed by measuring voided volume, residual volume, voiding time and urine flow rate.
