Aim: To investigate the voiding pattern in < 4 week old newborns by 12h daytime observation periods. Methods: Twenty-one healthy 1-28 d old newborns were included (10 full-term, 11 pre-term). The 12h free voiding parameters, including voiding frequency (VF), voiding volume (VV), post-voiding residual volumes (PRV) and status at voiding (awake/sleep) were recorded at day 1, 4, 7, 14 and 28 after birth. Results: Voiding was recorded 778 times. VF increased in the full-term and pre-term newborns between day 4 and 7, decreased in pre-terms between day 14 and 28 but remained higher than in the full-terms. VV increased twice in full-terms and once in pre-terms during 28 days and PRV fluctuated. In contrast, VV was higher in the full-term than the pre-terms at days 4, 7, 14, and 28. PRV was higher at days 4 and 28. Interrupted voiding was less frequent in the full- than pre-terms. Conclusion: Voiding pattern in the pre-terms differed in many ways from that of the full-term newborns. Frequent interrupted and incomplete voiding pattern in the preterm newborns indicates a disrupted coordination of the detrusor-sphincter and a delayed maturation of the neural micturition center. |
