OBJECTIVES: Urine collection from neonates and infants remains challenging. Non-invasive urine collection methods (UCMs) are preferred, but they are often associated with drawbacks, such as feces contamination, discomfort, and/or inaccurate urinary analysis. This study aimed to demonstrate the measurement accuracy and clinical usability of the Specturi urine collector device.
METHODS: 25 different urines were incubated in the Specturi urine collector device and three non-invasive UCMs, namely gauzes, urine collection bag, and PeeSpot, for 3 h at 37 °C. Albumin, calcium, chloride, creatinine, glucose, magnesium, phosphate, potassium, protein, sodium, and urea concentrations as well as osmolality and pH were measured in the extracted urines and compared to a control. The measurements were also compared between the different UCMs. In addition, a clinical pilot study was performed with the Specturi urine collector device to assess the usability and safety as indicated by nurses and parents.
RESULTS: The novel Specturi urine collector device offered accurate measurements of the various urinary analytes. Its measurement accuracy was comparable to the urine collection bag and PeeSpot and more accurate than gauzes. Nurses indicated that the Specturi urine collector device was easy to use, noting the ease of application and removal. Both nurses and parents indicated that the participants experienced no discomfort while wearing the Specturi urine collector device and no significant skin reactions were observed, unlike for other UCMs.
CONCLUSIONS: The Specturi urine collector device is a novel non-invasive UCM, offering accurate urinary analysis, ensuring patient safety and comfort, and providing easy usage by nurses.
