Abstract

Introduction: The concept of voiding patterns in neonates had not been completely understood. The voiding pattern in neonates was physiologically different from that in older children. The brain's development affects voiding patterns in frequency, bladder volume, and post-void residual bladder volume, as the child keeps growing. This study aims to understand the physiological neonates' voiding system in Indonesian newborns.

Materials and methods: We evaluate ten normal-born and 12 perinatology-hospitalized aterm neonates without anatomical or physiological urologic abnormalities at RSUP Haji Adam Malik from October to November 2019. We used an observational study, assessing the voiding physiology in newborns, including voiding frequency and urine volume. Infants with a history of urinary tract infection or present bacteriuria confirmed by urine culture were excluded. Voiding volume, frequency, bladder capacity, and residual volume were measured.

Results: We collected a total of 22 patients, with 12 patients were perinatology-hospitalized and ten patients were healthy neonates with ten subjects were male, and 12 subjects were female. There was no correlation between voiding frequency and total voiding volume with perinatology-hospitalized, healthy neonates, and sex. (p>0.05). Independent T-test was performed with a p-value for volume, frequency, bladder capacity, and residual volume of 0.225, 0.112, 0.031, and 0.663. We got a significant difference in bladder capacity between healthy neonates and perinatology-hospitalized. No significant differences were noted in other variables. Pearson correlation analysis was performed to determine the correlation between total voiding volume and age of gestation, body weight, length, head circumference, abdominal circumference, and chest circumference. The correlation coefficients were 0.772, 0.869, 0.623, 0.698, 0.079, 0.523 in order, with significant p-value in the age of gestation, body weight, length, head circumference, and chest circumference. There were correlations between total voiding volume and age of gestation, body weight, length, head circumference, and chest circumference. 

Conclusion: In conclusion, we found there was a significant difference in bladder capacity between healthy neonates and perinatology-hospitalized.
