A 9-year-old boy is brought to the
pediatrician's office for
bed-wetting. His mother states
that he has never been dry at
night. Occasionally, he has
problems controlling his bladder
during the day. On physical
examination, his blood pressure is
98/56 mm Hg. Both his weight and
height are below the 5th
percentile for his age. His
bladder is enlarged and palpable
above the symphysis pubis. Which
of the following is the most
likely cause of his problem?
A.
Obstructive uropathy

Primary polydipsia

Obstructive uropathy is uncommon in children. Unstable bladder will not present filled upto above the symphisis. By exclusion i would like to pick up Primary (psychogenic) Polydipsia.
