Abstract

Urolithiasis is an uncommon renal problem in paediatrics. Once identified, however, a thorough investigation should be performed to look for the underlying cause. Children with renal stone may present as haematuria, recurrent abdominal pain and urinary tract infection. Since abdominal colic is a common reason for medical consultation, rare cause like renal stone can be easily overlooked. We reported an infant presented as recurrent abdominal pain and positive urine culture. Subsequent work up revealed the diagnosis of Type A cystinuria.

尿路結石並非兒科腎臟疾病的常見原因。而一旦被診斷，就要進行全面的檢查以尋找潛在的病因。兒童腎結石可出現血尿、反覆腹痛發作和尿路感染。由於急腹症是臨床會診的常見原因，所以諸如腎結石這些罕見原因很容易被忽略。我們報導一例嬰兒，其表現為反覆腹痛和尿培養陽性，最終診斷是甲型胱氨酸尿症。
