Overview Symptoms Treatment Prevention

Cystinuria

• Flank pain or pain in the side or back
  • On one side only (unilateral) or -- rarely, both sides
  • Often severe
  • May be progressive, getting increasingly worse over days
  • May travel or radiate to lower flank, pelvis, groin, genitals
• Blood in the urine

Symptoms may indicate kidney stones. The doctor will not be able to determine the presence orcause of the stones with only aphysical examination.

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 (intravenous pyelogram) may show stones in the urinary tract.
