How do I know if I have cystinuria?

Signs & Symptoms

The initial symptom of cystinuria is usually sharp pain in the lower back or side of the abdomen (renal colic). Other symptoms may include blood in the urine (hematuria), obstruction of the urinary tract, and/or infections of the urinary tract. Frequent recurrences ultimately may lead to kidney damage.

Do cystine stones show up on CT scan?

Unlike calcium-containing stones, cystine stones do not show up well on plain x-rays. Tests that may be done to detect these stones and diagnose the condition include: 24-hour urine collection. Abdominal CT scan, or ultrasound.
