A frequency/volume chart or bladder diary is helpful in the evaluation of pediatric OAB symptoms. Ideally, these charts should encompass a 3-day period. This will allow assessment of the child’s functional bladder capacity.

A frequency/volume chart is used to record the volumes voided and the time of each micturition, day and night, for at least 24 hours. A bladder diary is used to record the times of micturitions and voided volumes, incontinence episodes, pad usage, and other such information as fluid intake, the degree of urgency, and the degree of incontinence. A record of the bowel frequency and any fecal soiling is also helpful.
