- Bladder scans in a standing position may be used to assess bladder volumes in children, shortening exam times and increasing efficiency vs supine scans.
Why this matters
- "Despite its widespread use in pediatric urology clinics, portable bladder scanning is an insufficiently studied tool that lacks standardized protocols," say researchers.
- Researchers examined pediatric patients diagnosed with daytime wetting, nocturnal enuresis, or nonfebrile urinary tract infection (n=60; mean age, 9.2 years; age range, 3-18 years; 85% girls).
- Each patient received a formal supine renal/bladder ultrasound and prevoid and/or postvoid bladder scans in both standing and supine positions; researchers compared these methods using repeated measures 1-way ANOVA.
- Funding: None.
- With the exception of postvoid supine scans, all bladder scanning estimates significantly correlated with ultrasound volume, with prevoid standing having the strongest correlation (r = 0.83).
- Prevoid scans in both positions significantly underestimated volume in children aged
- Both standing and supine scans overestimated postvoid volumes by 29 and 18 mL, respectively (P<.001>
- Sample size was small.
