2 Clinical Trials for Various Conditions
The goal of this clinical trial is to compare the Kosmos Automatic Bladder Volume to the manual annotated bladder volume in participants across gender (male and female), age (children ages 7-17 and adults 18-89), and BMI strata (low to normal and high BMI). The hypothesis it aims to evaluate is: The Pearson correlation coefficient between Kosmos estimated bladder volume and manually annotated bladder volume will yield more than 0.90. Participants will: * Have their full bladders scanned and bladder volume calculated using the Kosmos Ultrasound Diagnositic System by both a nurse and sonographer. * Participants will void and measure their urine volume. * Participants empty bladders will be scanned and bladder volume calculated using the Kosmos Ultrasound Diagnositic System again by both a nurse and sonographer. * Three sonographers will manually annotate the pre- and post-void exam images for each patient to calculate the manually annotated bladder volume.
ICU patients are at risk for catheter associated urinary tract infection. Frequently patients can't tell clinicians if they need to void if the catheter is removed. If clinicians know that an accurate volume measurement s of urine volume in the bladder can be obtained when the catheter is removed, catheters could be removed earlier and more frequently and thus possibly avoid an infection. For this study, measures with ultrasound (directly visualizing the bladder to measure), bladder scanner (partially blind measure with placement of scanner over the expected bladder location on the skin) and urine catheterized volume will be obtained. The investigators also want to know if the technology is user dependent. The study will include 2 levels of nurses RN and advanced practice RN (APRN) perform the bladder scanner. An APRN and MD will conduct the ultrasound. Ultrasound is technology primarily used by physicians but APRNs are using the technology technology more frequently. After these 4 measurements, the patient's nurse will perform an intermittent straight catheterization (catheter inserted, urine drained, and catheter removed) as the gold standard comparison.
