Insights
Determining infant bladder capacity is crucial for diagnosing voiding dysfunction. A case study found the Kaefer formula, based on nonanesthetized infants, best matched a healthy infant's first morning void volume.
Area of Science:
- Pediatric Urology
- Infant Development
- Voiding Dysfunction
Background:
- Accurate bladder capacity assessment is vital for children with voiding dysfunction.
- Current benchmark formulas for infant bladder capacity lack consensus.
- Various formulas exist, but their reliability in infants is debated.
Background:
Bladder capacity is essential in assessing children with voiding dysfunction, yet it is currently unclear how best to determine a benchmark bladder capacity; various formulas have been proposed.
Case Presentation:
This report details the unique case of an elimination communication Caucasian infant (< 2 years old) who achieved nighttime and daytime dryness by 6 months of age. His first morning voids were measured from 8 to 20 months of age and compared with three formulas: (1) the Koff formula, a widely used formula based on fill volumes in anesthetized infants; (2) the Kaefer formula, a formula based on fill volume in nonanesthetized infants; and (3) the Holmdahl formula, a formula based on frequency-volume charts in normal infants.
Conclusion:
This infant's first morning void was found to be most consistent with Kaefer's formula. Further research is required to determine if formulas based on fill volume in nonanesthetized infants provide the more accurate benchmark bladder capacity in infants.
