Feasibility of approximate measurement of bladder volume in male patients using the Lilium α-200 portable ultrasound bladder scanner.

Bladder volumes measured periodically by the Lilium α-200 during cystometry were strongly correlated with actual PVR or instilled volumes. However, they showed considerable variation and may not predict actual volume accurately. The Lilium α-200 is feasible for obtaining an approximate measure of bladder volume.
