Urinary retention in pediatrics is defined as the inability to void for more than 12 hours in the presence of a palpable bladder or a urine volume greater than expected for age.

Maximum urine volume calculation for age:  (age in years + 2) x 30ml.

Causes of urinary retention include mechanical obstruction, infection, fecal impaction, neurological disorders, gynecological disorders and behavioral problems.

The distribution is bimodal occurring between 3 and 5 years and 10 to 13 years.
