Abstract
AbstractIntroductionUroflowmetry is a noninvasive measurement of the volume of urine excreted over time. Conventional uroflowmetry has become the main modality of urine flow measurement within time. However, this method requires the patient to be present in the hospital or healthcare setting, thus sometimes making the patients feel uncomfortable to undergo the examination. This led to multiple measurements which are inconvenient for the patients. Mobile acoustic uroflowmetry (sono‐uroflowmetry) has been proposed as an alternative method of urine flow measurement due to its portability. This study aimed to evaluate the accuracy and reliability of sono‐uroflowmetry as compared to conventional uroflowmetry.MethodsElectronic databases searching were done using prespecified search strategy to retrieve articles related with uroflowmetry. In addition, hand‐search strategy was used to identify additional articles. Studies with participants who had undergone sono‐uroflowmetry were included. Voided volume, voiding duration, maximum flow rate, and average flow rate were identified and used to determine the outcomes of measurement. The quality of included articles was conducted using checklist for Diagnostic Test Accuracy Studies by JBI.ResultsInitial search yielded 335 articles with four additional papers identified through hand‐searching process. Six papers were retrieved and further used in the narrative synthesis. Five studies enrolled male participants, while only one of the papers enrolled female participants as additional subgroup analysis. Therefore, the meta‐analysis was performed by using only male participants. Based on the meta‐analysis results, there were strong to very strong positive correlation in voided volume, voiding time, average flow, average flow rate, and maximum flow rate between sono and conventional uroflowmetry.ConclusionSonouroflowmetry showed significant positive correlations to conventional uroflowmetry, signifying its use as an alternative of conventional uroflowmetry.
