Bar graphs showing water intake, 24-hour urine volume, urine osmolality and urine pH in <i>PRR</i>^UB−/− and <i>PRR</i>^UB+/+ mice on postnatal day P30.

<p>Despite no difference in water intake (A), <i>PRR</i>^UB−/− mice have increased urine volume (B), decreased urine osmolality (C) and increased urine pH after acidic load compared to <i>PRR</i>^UB+/+ mice.
