Cystinuria Diagnosis & Tests
Symptoms may indicate kidney stones. The physical examination is nonspecific.
Straining the urine may capture urinary tract stones when they are excreted. An analysis of the stones shows cystine. A urinalysis may show sediment and cystine crystals. A 24-hour urine collection shows an excess of cystine.
An abdominal CT scan, abdominal MRI, or abdominal ultrasound may show a presence of stones in the urinary tract. An IVP may show stones in the urinary tract.
