2. Figure 1
Urine cystine excretion by Type I/I cystinuria probands in relation to the theoretic threshold of solubility. Urine cystine (µmol cystine/liter) of individual morning urine samples between age 1 to 7years is plotted versus urine pH in relation to the theoretic threshold of cystine solubility.

3. Figure 2
Urine cystine excretion by four Type I/I stone forming cystinuria probands at various times of the day. Urine cystine (µmol cystine/liter) is plotted versus urinary pH: 5 to 7 a.m. (▪), 11 a.m. to 12 p.m. (X), 3 to 4 p.m. (•), and 8 to 10 p.m. (▵) in relation to the theoretic threshold of cystine solubility.

4. Figure 3
Urine cystine excretion by Type I/III cystinuria probands in relation to the theoretic threshold of solubility. Urine cystine (µmol cystine/liter) of individual morning urine samples between ages 1 to 7years is plotted versus urine pH in relation to the theoretic threshold of cystine solubility.

5. Figure 4
Urine cystine excretion by Type II/Normal cystinuria patients in relation to the theoretic threshold of solubility. Urine cystine concentration (µmol cystine/liter) of individual morning urine samples between ages 1 to 7years is plotted versus urine pH in relation to the theoretic threshold of cystine solubility.
