Note : Detection times vary depending on analytical method used , drug metabolism , tolerance , patient 's condition , fluid intake and method and frequency of ingestion . If his or her ability to produce urine is declining , fluid intake needs to be limited . Fluid and sodium intake was standardized for all children , based on their weight , to eliminate the possibility that enuretic episodes were related either to excess sodium or fluid intake . Increased fluid intake increases the urinary output , thereby lowering the concentration of the substances involved in stone formation . Prevention is by maintaining an adequate fluid intake to ensure the continued passage of clear and copious urine , especially during physical exertion .
