One thousand consecutive full-term healthy Nigerian babies delivered at Ahmadu Bello University Teaching Hospital Zaria, were studied for the time of passage of the first urine and stool. By 6 hours of postnatal age 42%, 12 hours 76%, 24 hours 95% and 48 hours 99.8% of babies had passed their first urine. Similarly 56%, 81%, 96% and 99.8% of babies had passed meconium by 6, 12, 24 and 48 hours respectively. It is suggested that apparently healthy neonates who have not passed urine and meconium by the age of 12 hours should be closely observed and those who have not done so after 24 hours should be investigated for congenital abnormalities of the lower gastrointestinal and urinary tracts.
对在扎里亚阿哈穆杜·贝洛大学教学医院分娩的1000名连续足月健康尼日利亚婴儿，研究其首次排尿和排便的时间。出生后6小时，42%的婴儿排尿；12小时，76%；24小时，95%；48小时，99.8%。同样，分别在6、12、24和48小时，56%、81%、96%和99.8%的婴儿排出胎粪。建议对12小时龄仍未排尿和排便的看似健康的新生儿进行密切观察，而24小时后仍未排尿和排便者，应检查是否存在下消化道和泌尿道先天性异常。
