A bladder scanner is a non-invasive medical device that measures the volume of urine in the bladder. This technology can be safely and effectively used on babies to assess bladder function. Its non-invasive nature is a significant advantage, especially for infants.
Understanding Bladder Scanners
A bladder scanner operates using ultrasound technology, which involves transmitting harmless high-frequency sound waves into the body. These sound waves travel through tissues and liquids, echoing back when they encounter the bladder. The device then captures these echoes and uses them to create an image of the bladder. Algorithms within the scanner analyze these reflected sound waves to precisely calculate the amount of urine present in the bladder. This process provides a quick and accurate measurement of bladder volume without requiring any internal procedures.
Clinical Applications for Infants
Bladder scanners serve various purposes in the assessment of infant urinary health. They are frequently used to check for urinary retention, a condition where a baby cannot fully empty their bladder. Monitoring for post-void residual (PVR) volume – the amount of urine remaining in the bladder after urination – is another common application, especially in cases of frequent urinary tract infections (UTIs). This helps healthcare providers evaluate the efficiency of bladder emptying and can guide decisions regarding further intervention. While a valuable tool for assessment and monitoring, it functions as an aid in understanding bladder function rather than a definitive diagnostic tool for complex underlying conditions.
Advantages and Considerations for Pediatric Use
Using a bladder scanner for infants offers several benefits. It is non-invasive, eliminating uncomfortable procedures like catheterization and reducing the risk of infection. The scan does not involve radiation exposure, making it a safer alternative compared to imaging techniques that use X-rays. Results are typically quick, allowing for immediate clinical decisions. However, while bladder scanners are excellent for measuring volume, they do not provide detailed anatomical information about the bladder or kidneys. Accuracy can be influenced by factors such as the baby’s movement or the technique used during the scan, and studies suggest accuracy may be lower in very young children.
What to Expect During a Bladder Scan
During a bladder scan, the baby will typically lie comfortably on their back. A small amount of ultrasound gel, which may feel cool, will be applied to their lower abdomen. A healthcare professional will then gently place a handheld probe on the skin over the gel. The scan itself is very quick, usually lasting only a few seconds, and is a painless procedure for the baby. The results, showing the bladder volume, are often displayed immediately on a screen, allowing the healthcare team to interpret the findings without delay.
