A 2-year-old girl presented with intermittent dysuria. Following triage in paediatric A+E, the nursing staff became concerned with the large sample of colourless urine she produced, which tested positive for leucocytes. She was described as a 'big drinker' to the SHO, raising concerns about diabetes insipidus. On detailed questioning it emerged that she had recently drunk a herbal tea preparation (buchu, couchgrass, marshmallow and plantain) to help 'flush out' her urinary system. She was advised to stop the tea. She had localised genital irritation and was discharged home with hygiene/barrier advice, pending urine culture results. She represented 2 days later with worsening dysuria and fever. Her urine was of normal colour and tested positive for leucocytes, nitrites and blood, hence she started antibiotics (urine cultures subsequently grew coliforms). Herbal use in children is not uncommon and should be considered as a cause of polyuria.
一名2岁女童出现间歇性排尿困难。在儿科急诊室分诊后，护理人员对她排出的大量无色尿液感到担忧，尿液白细胞检测呈阳性。她被向住院医生描述为“饮水量大”，这引发了对尿崩症的担忧。经过详细询问，发现她最近喝了一种草药茶制剂（布枯、茅草、锦葵和车前草）来帮助“冲洗”泌尿系统。建议她停止喝茶。她有局部生殖器刺激症状，在等待尿液培养结果期间，带着卫生/屏障方面的建议出院回家。两天后她再次就诊，排尿困难加重并伴有发热。她的尿液颜色正常，白细胞、亚硝酸盐和血液检测呈阳性，因此开始使用抗生素（尿液培养随后培养出大肠菌群）。儿童使用草药并不罕见，应考虑其为多尿的一个原因。
