Warm  welcome to Healthcaremagic.com
I have evaluated your query for  daughter in details  .
*  This indicates mild  
cystitis  probably .
*  Guidelines for better  recovery 
Allow her to  drink plenty of liquids .
Cranberry half sachet once daily in a glass of  drinking water , organic citrus  fruits , 
vitamin C  supplements  help a lot .
Necessary antibiotics , urinary alkalisers , anti inflammatory  medications  
require  prescription of your doctor  ( who may decide depending upon your 
evaluation with required blood and  urine  tests .
Keep the genitals clean with antiseptic  liquids , dry .
Wear loose , clean , cotton inner wears .
Avoid  exposure  to  excess heat .
*  Answer for second question about her normal urine output  is
    1 - 2 ml / kg / hr  that  is  20 - 40 ml  / hr and  480 - 960 ml  /  day
    depending upon the oral intake  and  other  factors .
